2 Agenda Today’s data protection reality The usual answers Avamar overviewHow it worksFlexible deploymentAvamar solves customer challengesSummaryLet’s start by reviewing today’s data protection realities and some traditional answers. Then I'll provide an overview of Avamar technology, how it works, and how it solves backup and recovery challenges in new ways. Along the way, I'll provide you with real customer examples and, at the end of the presentation, I'll summarize what we've talked about and answer any questions you may have.
3 Today’s Data Protection Reality Pressure to meet the changing needs of the businessData growth is immenseCompanies want more data protectedTime required for backup is expandingBackup hampered by tape’s unreliability and poor performanceVirtual machines pose unique backup challengesIncreasing volume of data at remote officesMore data stored locally on desktops and laptopsLet’s take a look at the reality of providing quality data protection today.Data continues to grow at double-digit rates, and the time necessary to back up that data is growing proportionally, while available backup windows continue to shrink. As companies want to protect more data across more sites, the task becomes even more challenging.If you’re like most companies, tape continues to have a place in your backup environment, despite its well- documented reliability and performance issues. Perhaps you want to reduce your reliance on tape—or eliminate it—especially at remote or distributed sites.Virtual machine backups and remote office data growth are becoming more critical to enterprises of all sizes. There has been a sharp increase in the deployment of virtual machines in production environments. Virtual machines bestow great benefits by consolidating physical servers, but they create an immediate backup challenge because of all the consolidated—and in many cases, duplicated—data that needs to be backed up through physical hardware and networks. In addition, there has been a significant increase in the amount of data residing at remote offices and on desktop/laptop systems, where data protection practices tend to be manual, inconsistent, and decentralized.
4 The Usual Answers Traditional backup and recovery Backup to tape, or stage to disk, and then archive to tapeManually move tapes offsite for disaster recoveryTraditional backup and recoveryInefficient and slow, ~200% of primary data moved across the network weeklyTedious, multi-step recovery processRisks the loss or theft of unencrypted tapes in transitData is difficult to recover and leverageWhat are most companies doing today?Most companies still rely on traditional backup software to back up to tape. They may stage to disk first—in the form of virtual tapes, or do disk-to-disk backup—before moving data off to tape for long-term archive. Typically, tapes are still manually shipped offsite with trucks for disaster-recovery purposes. You have two issues: the first is the limitations of the traditional approach and the second is a heavy reliance on tape.The problem with traditional backup is that it’s extremely inefficient and slow, especially for remote sites and virtual systems. Many users implement a weekly full backup along with daily incrementals using traditional backup software. The result is that approximately 200 percent of the production data is moved across the network and stored every week. And this doesn’t even take into account the amount of redundant data that exists across multiple locations and servers.And when it comes time to recover data, the traditional process is tedious and unreliable, usually involving the layering of incremental backups onto the last full backup to reach the desired recovery point. In addition, in many cases, the tape-based backup data can’t be recovered, but this isn’t discovered until it’s too late.Needless to say, whenever tapes are manually shipped there is an inherent risk of loss or theft. There have been many unfortunate and highly publicized examples of large corporations and financial institutions exposing confidential financial and customer information due to lost or stolen tapes. Regulations now require that the information be made public when that happens.Finally, for all the effort of conducting traditional backup, the result is little more than disaster insurance. Data is locked on tape in chunks that often can’t be immediately leveraged.
5 Avamar Virtual Edition for VMware Avamar OverviewAvamar SoftwareAvamar Data StoreAvamar Virtual Edition for VMwareAvamar server deployed as a virtual applianceAgent-only or deployed on qualified, industry- standard serversFully integrated software/hardware offeringBackup and recovery software with integrated global, source data deduplicationReduces the size of backup data at the source— before it is transferred across the networkDelivers fast, daily full backups using existing infrastructureReduces network bandwidth for backup by up to 500 timesDeduplicates across sites and servers, reducing total backup disk storage by up to 50 timesCost-effectively stores daily full backups on disk—reducing or eliminating the need for tapeIdeal for protecting VMware environments, remote offices, LAN/NAS servers, and desktop/laptop systemsAvamar's backup and recovery software has an important difference—Avamar’s unique global, source data deduplication technology eliminates the unnecessary transmission of redundant backup data that is sent over the network and stored. This defuses the enormous amount of data growth both in core data centers and out at remote offices. Avamar deduplicates at the source and across sites and servers. As a result, Avamar technology can dramatically reduce the amount of time required for backups and reduce the impact on the network. This data reduction also alters the fundamental economics of disk versus tape, allowing companies to cost-effectively backup data to disk at a cost that is equal to, or less than, tape.Avamar delivers fast, daily full backups and one-step recovery—including point-in-time recovery for Oracle, DB2, and SQL Server databases—eliminating the hassle of restoring your last good full, plus subsequent incremental backups. Avamar stops the avalanche of full and incremental backup data before it forms— reducing backup times, client resource consumption, and network impact. Avamar delivers far better data reduction than other approaches to deduplication on the market.Note to Presenter: For additional information on Avamar's data reduction ratios of up to 500:1, refer to the "Frequently Asked Questions: EMC Avamar" on Powerlink at this path: Products > Software A-B > Avamar > FAQs.
6 Avamar: How it Works Global, sub-file data deduplication Break data into atom (sub-file, variable-length segments of data)Send and store each atom only onceAvamarbackup repositoryOHOGlobal data deduplication at the source is the unique technology that drives all of Avamar’s advantages and is the real reason Avamar is able to solve key enterprise data protection challenges.Enterprise data is highly redundant, with identical files and sub-file data segments stored within systems and across systems company-wide. Traditional backup software magnifies the problem by storing redundant data over and over again. Avamar solves this problem by viewing primary data in chunks called data segments. The software generates and assigns each data segment a unique ID, based on its content, which is used to compare it with other data segments that have already been backed up. Only new, unique data segments are transferred during a backup operation, ensuring that only a single instance of each segment is stored in a central location. Avamar eliminates redundant backup data at the source—before that data is sent across the network. It also deduplicates across sites and servers, hence the term “global.”How does it work? If you think about the entire world we live in today, realize that it could be reconstructed from 117 elements. If you stored one atom for each of those 117 elements, and then reused those atoms again and again, all you would need was the map that would rebuild all of the objects that make up our world today. That’s an extreme example, but that is basically what the concept is.So that’s essentially what Avamar is doing. It breaks data down into its elemental components, which EMC calls variable-length sub-file data segments. These are unique patterns of zeros and ones—and each of these unique segments is stored just once across the entire enterprise environment—across sites and servers.As shown, data is deduplicated at the source through an Avamar software agent, which allows for that dramatic reduction in network consumption during daily full backups.Deduplication also happens on the Avamar server, so that only new, unique sub-file variable length data segments are stored to disk across sites and servers, reducing the total back-end disk storage by up to 50 times.Finally, Avamar uses extremely efficient deduplication technology. Each sub-file variable-length data segment is just 12 KB on average. As a result, Avamar dramatically reduces backup times, the impact on the backup network, and the required back-end disk storage for cost-effective retention on disk and fast, single-step recovery.HHOHOHOHHOHAt the source—Deduplication before data is transported across the networkAt the target—Assures coordinated deduplication across sites, servers, and over timeGranular—Small, variable-length sub-file segments guarantee most effective deduplication
7 Avamar: How it Works Simple example of global, sub-file deduplication DataCenterRemote Site 1Duplicate InstanceData already backed up,so only unique IDs stored (20 byte pointers)RemoteSite 2Modified InstanceFirst InstanceLet’s bring it up a level and look at a specific example of global data deduplication at the source. Let’s say you have a PowerPoint presentation.In the first step, Avamar software breaks the PowerPoint presentation into sub-file variable-length data segments—A, B, C, and D. Let’s assume this is a new presentation that has never been backed up before. Because each data segment is new, all segments are backed up to the Avamar server.Note to Presenter: Click now in Slide Show mode for animation.In Step 2, there is a duplicate instance of the same PowerPoint presentation—perhaps as a result of someone ing the presentation to a co-worker. In this case, Avamar software on the client side recognizes that data segments A, B, C, and D have already been backed up to the central Avamar server. As a result, only a unique ID pointer, which is a very small 20-byte file, is sent and stored.In Step 3, someone has edited a portion of the PowerPoint presentation. During the next backup operation, the client checks both its local cache and the Avamar server to see which segments have already been backed up. Only the new, unique sub-file variable-length data segments associated with the changes to the file will be sent to the Avamar server. In this case, data segment E is new, so only this data segment is transferred during the backup.What’s really important about Avamar’s deduplication is that it doesn’t matter if the change is at the beginning of the file, at the end of the file, or in the middle… the software will find and identify the changed data segments and only back up the changes.Note to Presenter: Here’s some background information…ABCDEOnly unique data segments are backed upNew data segment identified and backed upDeduplication server(stored backup data)ABCDETraditional backup:2 MB for original file+2 MB for duplicate file+2 MB for changed file6 MB totalAvamar backup:+0 for duplicate file+200 KB for changed file 2.2 MB totalDifference:MB less data- Repeated hundreds or thousands of times across the enterprise- Data is backup up only once for full backups

There’s a great deal of confusion about deduplication ratios. Keep in mind that an Avamar daily backup, which is what we’re looking at in this chart, amounts to a full backup so these numbers are in comparison to doing a daily full backup.Also, keep in mind that with any backup, including Avamar, you will store the initial full backup, plus the changes. Avamar does deduplicate within the initial full and can get you up to 70 percent reduction, depending on how much duplication exists. Still, when evaluating storage capacity, which EMC can help you do, you need to take into account primary data, plus retention policies. Avamar’s savings are dramatic here, too. In traditional backup scenarios, EMC has seen customers require storage that’s 10 times or even 25 times their primary data—to store several months’ worth of weekly full and daily incremental backups. Avamar might require one, two, or three times, and will deliver the same retention periods, plus much easier restores.Now, let’s look at the chart specifically…Avamar has industry-leading deduplication technology and the numbers in this chart are based on real-world customer examples. As you can see, depending on your data mix, you’ll get different levels of data deduplication.For Windows and UNIX file systems environments, where there is a lot of duplication of operating systems, applications, and at the file level, you will see the highest levels of data deduplication.When it comes to a mix of file systems and databases, deduplication levels are slightly lower, but still impressive.While the numbers are impressive overall, it’s really the benefits that companies achieve when using Avamar that’s exciting. You can achieve new levels of data protection in historically problematic areas for backup and recovery, while driving improved total cost of ownership.Note to Presenter: The most important point about deduplication ratios—both for competitive products and EMC’s—is that results may vary. The amount of deduplication achievable depends on a number of factors, including type of deduplication (file-based, sub-file, etc.), retention policies, data change rates, and data types.Source: EMCWhile results will vary by data type and mix, Avamar candramatically improve backup performance and efficiency

Companies require high availability solutions and guaranteed recoverability of data, and Avamar delivers with a valuable set of patented technologies.Avamar uses patented Redundant Array of Independent Nodes, or RAIN technology, to deliver high availability. RAIN works in a very similar way to RAID. If you lose an Avamar server node, Avamar can read/write around that, which means backups and restores can continue without interruption.Avamar uses a grid architecture, which makes it easy to increase performance or disk capacity in a very granular fashion, and data is automatically load-balanced across all the available resources in the grid.The Avamar server automatically checks itself twice daily using internal checkpoints. If a problem is detected, the server will roll back to a previous checkpoint. Also, Avamar verifies that backup data is fully recoverable, automatically every day—so there are no surprises when a recovery is needed.And of course, there is also RAID protection in each of Avamar’s servers.These high-availability features ensure that Avamar provides the reliability that companies of all sizes require.Parity across storage nodesUtility andspare node

In order to facilitate the management of these distributed Avamar deployments, Avamar delivers the ability within a single interface to monitor and manage multiple Avamar systems. Avamar’s at-a-glance dashboard allows Backup Administrators to quickly assess both the status of backups across the enterprise as well as the status of all Avamar systems in a distributed Avamar deployment. The dashboard also enables users to quickly drill down into a particular Avamar system to manage that system or to review granular system and backup status.Data protection for desktop/laptops is available with Avamar 5.0 and higher, which comes with a specialized management module designed to manage thousands of workstations.

12 Avamar’s Flexible Deployment Now let’s review some of Avamar’s flexible deployment options.Lightweight, efficient Avamar agents are always deployed on systems to be backed up. They deduplicate at the source and then send any new, unique sub-file data segments to an Avamar server that can be local or connected through a WAN. When it comes to remote offices, Avamar give you flexible deployment options. For small remote sites, you can simply place Avamar software agents on the primary systems to be protected with no additional local hardware needed, and back them up directly across the network to a main data center or disaster recovery site.For larger sites, you may choose to back up locally to an Avamar server for fast local backup and recovery. Then that Avamar server can be replicated to a disaster recovery site, hub site, or data center, if required.There are also areas in the data center where Avamar can deliver substantial value for protecting LAN-attached servers. VMware is a great example of this, that I’ll cover in more detail later, as are LAN-attached file servers with larger amounts of Windows or UNIX data. All data can then be encrypted and replicated, if desired, through another Avamar server at a remote site.The Avamar server at the remote site can periodically write data to tape in deduplicated format using Avamar Data Transport for cost-effective retention on tape.Avamar is complementary to other EMC products, including NetWorker, Data Domain, and Centera.

The multi- node Avamar Data Store is ideal for deployment in the data center where backup data is being consolidated from multiple remote locations or to protect VMware environments and LAN-attached servers. Avamar Data Store's single-node model is ideal for remote offices or small data center environments that require faster recovery performance. Both models have similar functionality, differing only in capacity, upgradeability, and high availability options. In addition, both models support replication, either from the remote office to the data center for consolidation or between data centers for disaster-recovery purposes.The multi-node Avamar Data Store configuration starts at 4 TB and scales to support up to 52.8 TB of licensable deduplicated backup capacity (which, under a typical backup schedule, could require up to several petabytes of traditional disk or tape storage, depending on the backup method and retention period). With RAID-protected storage, redundant power distribution, and RAIN, the multi-node Avamar Data Store delivers this protection with high availability.The single-node Avamar Data Store is available in 1 TB, 2 TB, and 3.3 TB of licensed deduplicated backup capacity configurations and provides the ability to retain the equivalent of up to 114 TB of daily full backups on non-deduplicated disk or tape storage.**Equivalent traditional backup capacity assumptions:100 percent Microsoft Office file data, weekly full and daily incremental backups, no compression, 10 percent daily change rate, 90-day retentionFor Avamar, we are assuming daily full backups (Avamar always provides daily full backups), RAIN for high availability, and that the backups occur to system capacity

This means significant savings in tape media and in the total cost of offsite storage because fewer tapes are required.Here’s how it works…Avamar backs up clients as usual to the Avamar server.Then, backup data is replicated as defined by user policy to Avamar Data Transport replica nodes that reside as guests on VMware ESX servers. Note that having a VMware ESX server is a requirement for the solution.From there, Avamar Data Transport coordinates the export of these replicas, using either EMC NetWorker or Symantec NetBackup, to physical tape so that deduplicated data is stored on tape.Because of searchable metadata stored in a file-level catalog and a fully automated, policy-driven process for restoring the Avamar deduplicated data from tape, data can be quickly rehydrated and restored to production using the Avamar Data Transport user interface.Fewer tapes for lower costs— up to 50 times reduction in long-term storage costs

19 VMware Backup Challenges Virtualization changes server, application, and information paradigm…backup must evolve to deliver even greater consolidation and valueOld ParadigmPhysical environment: Low overall server utilization and plenty of bandwidth for backupNew ParadigmVirtual environment: High overall server utilization and little bandwidth for backupVMware changes your server and application IT environment.Server utilization has commonly run as low as 5 percent to 20 percent. Because virtualization can make a single physical server act like multiple logical servers, it can improve server utilization by combining numerous computing resources on a single server. VMware allows users to run 10 or more virtual machines on a single server, increasing server utilization to 60 percent to 80 percent. Maximizing your server utilization results in the reduced amount of hardware, power, cooling, and space costs.Virtual server backups can be accomplished using a traditional approach with conventional backup software. The backup software is simply installed and configured on each virtual machine, and backups will run normally to any conventional backup target, including tape drives, virtual tape libraries, or disk storage. However, applying traditional backup tactics to virtual server backups does have drawbacks. The most significant challenge is resource contention. Backups demand significant processing power, and the added resources needed to execute a backup may compromise the performance of that virtual machine and all virtual machines running on the system—constraining the VMware host server's CPU, memory, disk, and network components— and often making it impossible to back up within available windows.Backup processes must evolve to deliver greater efficiencies in your highly consolidated environment.

Avamar quickly and efficiently protects virtual machines by sending only the changed segments of data on a daily basis, providing up to 500 times daily reduction in network resource consumption compared to traditional full backups. Avamar also reduces the traditional backup load—from up to 200 percent weekly to as little as 2 percent weekly—dramatically reducing backup times. Avamar can either be used to back up at the guest level—an individual virtual machine—or at the VMware Consolidated Backup server. In addition, Avamar software negates the need for transporting tapes to offsite repositories for disaster-recovery purposes by providing remote replication services over standard WAN connections.Second, Avamar’s deduplication is sub-file and variable length. This is the optimal granularity to find changes anywhere within a virtual machine disk format (VMDK), and this is where fixed-length deduplication fails to deliver the amount of data deduplication that Avamar does with source-based, variable-length deduplication.

Avamar has universal support for guest-based backup support (where an Avamar agent is installed inside the virtual machine) and VMware Consolidated Backup (where an Avamar agent is installed on the VMware Consolidated Backup proxy server).Avamar is also fully integrated with the new vStorage API that comes as part of vSphere 4 and provides a more robust platform for VMware Consolidated Backup backups. This gives you more flexible backup policies (file or image level), incremental VM backup, and multiple restore options. To manage this new VMware Consolidated Backup environment, EMC has integrated the vCenter Server module into the Avamar management platform. This allows you to manage VMware Consolidated Backup throughout the Avamar user interface and provides a single point of management for all available backup options.Note that these new features and functionalities associated with image-level backup are byproducts of Avamar’s integration with the vStorage API for data protection. This API provides common functionality for all third-party backup software vendors who support it.That said, Avamar’s VMware backup differentiation remains, where deduplicating data prior to moving it across the network still remains its key value, enabling 90 percent faster VMware backups and 50 percent greater server consolidation.

The backup configuration for this method is no different than that for a physical server. Configuration beyond basic client setup might be needed to support a specific application, such as Microsoft SQL Server, Oracle, or Microsoft Exchange. The main advantages of this are:Highest level of data deduplicationSupport for backup of applications inside the virtual machinesSupport for partial restores or file-level restoresIdentical backup methods for physical and virtual machinesNo requirement for advanced scripting or VMware software knowledgeUnchanged day-to-day procedures for backup

25 Remote Office/Branch Office (ROBO) Backup challenges and Avamar solution The “Achilles’ heel” of data protectionMore than 4 million remote offices in the U.S.Remote office data growing at more than 50% per year*Most back up to tape and move unencrypted tapes offsiteOften unskilled, untrained IT staff at remote sitesAvamar remote office/branch office backup is simple, safe, and manageableExtend data center protection to the edgeFast, daily full backups and one-step recovery through existing WAN/LAN linksAvamar agent-only deployment for smaller offices (no extra local hardware)Eliminate distributed tape management/infrastructureMitigate risk involved with manually shipping tapesData encrypted in-flight and at-rest for securityThere are more than 4 million remote offices in the U.S. alone, and data stored in these locations is growing by more than 50 percent each year. Gartner Group also documented the fact that 60 percent or more of all enterprise data is stored at remote sites, outside of the data center.Why is this a problem? There really is no “standard” remote office, and most do not have skilled onsite IT staffs. Many do not encrypt their backups, and most still rely on manually moving tapes offsite for disaster recovery.Avamar’s capabilities let you extend your data center’s best practices to the remote office in an affordable manner, by minimizing the time, effort, and most importantly, the consumption of network bandwidth necessary to back up and protect the growing amount of data stored at remote offices.Avamar also eliminates the complexity and tape infrastructure needed to protect data at remote offices. Avamar is able to deliver secure, encrypted electronic backups. Avamar also has a true multi-site/single interface for management, which allows centralized, simple management of your remote office backups.As a result, the technology allows you to minimize the distributed backup infrastructure that you must maintain at remote offices—no more local tape drives, media servers, or tape management nightmares. And with fewer tapes in transit, clearly the risk of lost or stolen tapes is greatly reduced.Note to Presenter: For details on the Virginia Department of Motor Vehicles customer example, see slide 41.“Avamar enabled us to reduce administrative support requirements by 80%, reduce backup windows by 90%, and recover lost files and servers in minutes rather than hours.”Mike DePhillip, Backup Administrator, Virginia Department of Motor Vehicles*Source: Gartner
26 NAS Filer Backup and Recovery Challenges Limited backup windowsDaily full backups desired, but not feasibleLimited backup and recovery performanceSingle filer controllers have limited resources and can become a bottleneckIncomplete backups leave data at riskLimited network links and disk storageRedundant data limits performance of network/ infrastructure and requires more disk storageImpact on end usersWhen backups exceed allotted window, end users compete for the NAS resources (poor response, lower productivity)NDMP licensesTraditional NAS filers require expensive NDMP licenses to support backup and recoveryAs with many IP-based backup solutions, the network is often a weak link in the process, either because there isn’t enough bandwidth to meet the needs of the backup, or because the cost required to assure adequate bandwidth is high. And even when there is adequate bandwidth, streaming terabytes of data across the network on a regular basis for full backups can still be a burden to network resources.At the same time, recovering data from full and incremental backups is complex and time-consuming. A simpler solution would involve eliminating the use of incremental backups and doing only daily full backups of the NAS environment. But this isn’t practical when full filer backups can extend beyond available weekend backup windows.For many businesses, it is often the case that the NAS backup extends into the time of day when end-user productivity is dependent on the network and filer resources. Competing with a long-running backup for network and filer resources usually leads to poor network performance and lower end-user productivity.

The initial Avamar backup of the NAS environment is a full backup (level 0). From that point on, all of Avamar’s backups of the NAS environment are incremental (level 1) backups that take significantly less time to complete than a full backup. And just as important, since each Avamar incremental backup is stored as a full image backup, recovery becomes a simpler and less time consuming one-step process of restoring from the full backup image. With Avamar, there is never a need to restore from full and incremental backups to reach the desired recovery point.Avamar’s data deduplication at the source technology ensures that only non-redundant data is stored on the Avamar server. Moving less data means lower costs for backup media and backups that are up to 10-times faster than NDMP full backups.Once data has been backed up to the Avamar server, the backup can then be encrypted and replicated, if desired, to another Avamar server at a remote site using existing network bandwidth. Replication of encrypted data to a remote Avamar server provides a simple and secure disaster recovery solution offering numerous benefits including:Reduced or eliminated costs associated with transporting and storing tape media offsiteMitigation of the risk of backup tapes falling into the wrong handsElimination of failed restores because of unreliable tape mediaLastly, Avamar provides flexible options for recovery including the ability to restore the entire file system or just individual files. And the restore can be directed to any other Avamar supported client, including Linux, UNIX, and Windows servers. This restore flexibility is not possible with traditional backup solutions.After AvamarDailyFullDailyFullDailyFullDailyFullDailyFullDailyFullDailyFull

Similarly, with the help of a powerful search engine, they can restore their own files at anytime, from anywhere, without contacting their IT Help Desk.Customers gain all the benefits of Avamar for desktop/laptop protection as they do for their data center and remote office backups. It includes data deduplication, open-file backup, and CPU throttling—all in a small client footprint taking up only 5 MB. And since its Avamar technology, it requires little bandwidth by never backing up the same data twice, providing up to a 500-times reduction in network bandwidth used when compared to other backup solutions. It operates in the background, nondisruptively to the end user.Windows or Mac OS XAvamar Data Store
30 Avamar’s Unique Value Deduplicates data at the client (source) Fast, daily full backups through existing infrastructureDeduplicates data globallyReduces required backup disk storage by up to 50 timesFast, single-step recoveryEliminates hassle of recovering last good full and subsequent incrementals to reach desired recovery pointRecoverability verified dailyDaily server integrity checks; data recoverability verified dailyHigh availabilityRAIN architecture and replication—no single points of failureCentralized managementStreamlines administration and management of remote backupsFlexible deployment optionsComplete solution from EMCBackup, recovery, disaster recovery, and data deduplicationThere are many technologies on the market for backup and recovery, but Avamar has truly unique value.Traditional backup and recovery software may offer incremental backups, but those products don’t deliver deduplication that stores sub-file segments once and only once across the entire enterprise.Avamar’s innovative agents, in contrast, deduplicate at the source (client) before data is transferred across the network, providing the kinds of ratios described earlier—up to 500:1 reduction in network impact. Avamar also enables shorter backup windows; daily full backup are up to 10 times faster across existing network bandwidth because of that tremendous data reduction. In addition, those Avamar agents can be deployed on VMware virtual machines or on VMware proxy servers, delivering tremendous deduplication efficiency within and across virtual machines.Unlike other products on the market, Avamar also provides high availability at the server, enabling you to confidently and cost-effectively store years’ worth of backups on disk storage—and now, with Avamar Data Transport, to export Avamar deduplicated data to tape for long-term storage.And here’s an extremely important differentiator. Unlike traditional backup software (or traditional software plus a deduplicating virtual tape library), which requires you to restore your last good full and then all subsequent incremental backups, Avamar delivers immediate, single-step recovery. Thus there is no need to restore from full and incremental backups to reach the desired recovery point.Additionally, the Avamar Server Recovery option combines Avamar 5.0 with EMC HomeBase to provide tighter server-system backups and restores, as well as bare-metal recovery. A HomeBase client is installed with the Avamar client to enable Avamar to provide hardware independent server-level recoveries through the Avamar user interface.

This is why EMC has integrated the two products.Note to Presenter: Click now in Slide Show mode for animation.First, EMC has integrated the NetWorker and Avamar clients as well as communication between NetWorker Management Console and Avamar.This allows deduplication node resources to be presented in NetWorker Management Console, and the user can create, edit, or delete deduplication nodes in the manner similar to other resource types.New attributes were also added to the client resource to enable deduplication. Users can create new deduplication clients, or convert existing ones. You manage client resources following same workflows as before.Once the save process begins, it gathers the metadata to send to the NetWorker server, and deduplication data is sent to the deduplication node.Recovery is accomplished from the NetWorker recovery interface (GUI or CLI). Once the metadata associated with the data needing to be recovered is identified, the required deduplicated data is restored from the deduplication node and the data is rehydrated.DataClientsMetadataDataMetadataServerManagementConsoleNetWorkerNetWorkerDeduplicationnodeAvamarData StoreNetWorkerStoragenodeDisk, VTL,Tape

Problems meeting backup windows and rising administration costs for the backup process compelled St. Peter’s to find a faster, more reliable, and easily scaled backup solution. Driven by expansion and regulatory compliance requirements, the hospital also needed to ensure uninterrupted operations and integrity of its data during a move into a new data center. To secure the highest possible hospital ratings, St. Peter’s had to meet the standards set by the Joint Commission on Accreditation of Healthcare Organizations (JCAHO).To satisfy these requirements, the hospital initiated a search for a more robust disk-based backup and restore solution as well as a disaster recovery solution. Out of all the solutions evaluated, Avamar provided the best mix of reliability and economy. Avamar has enabled St. Peter’s to improve productivity by reducing data recovery time objectives because backups can now be performed during production hours—without impacting critical applications. In addition, Avamar’s policy-based management capabilities have allowed the hospital to efficiently and finely control various aspects of their backup operations.Note to Presenter: For additional information about St. Peter’s Health Care Services, refer to the complete customer profile on EMC.com: ldv.pdf.Note that as of 1/1/07, The Joint Commission on Accreditation of Healthcare Organizations (JCAHO) became The Joint Commission.“Avamar provides a huge time and cost savings for backup of multiple virtual machines.”With Avamar, we can centrally manage all of our backups, and we also gain the ability to rapidly restore data down to the file level.”Curtis Damhof, Network Manager, St. Peter’s Health Care Services
39 Before Avamar With Avamar USE CASE Global Industrial Manufacturer Backing up a VMware infrastructureBefore AvamarStruggling to meet backup, recovery, and reliability goals across extended enterpriseLengthy backup windows caused by increasing data volumes, threatening network performanceExpanding existing backup solution would require second master server, two additional tape silos, 16 new LTO tape drivesWith AvamarBackup for VMware (24 ESX servers, 332 virtual clients)Avamar agents installed in VM guestsEliminated physical tape managementReduced backup and recovery administrative burdenBackup performance increased ten-foldBackup network traffic reduced by 95%OPTIONAL SLIDEA data protection example of a VMware infrastructure with Avamar is this global industrial manufacturer. The company, operating in more than 100 manufacturing facilities and working with affiliates in more than 50 countries worldwide, was struggling to meet backup and recovery service levels across its extended enterprise. Its backup environment—which consisted of HP Data Protection, an HP server, and two HP tape silos—could no longer meet the demands being placed on it. Lengthy backup windows caused by increasing data volumes threatened network performance. Recovering lost data often took hours or even days.Expanding the existing backup solution would have required the purchase of a second master server, two additional tape silos, 16 new LTO (Linear Tape-Open) tape drives, as well as the reallocation of existing clients. It would have also significantly increased the administrative burden on the already taxed backup team.To meet its backup and recovery challenges, the company purchased two 13-node Avamar Data Stores, one located at headquarters and one at a disaster recovery site, backing up 14 TB of data and applications on Microsoft Windows, Microsoft Exchange, VMware, and Oracle servers at sites in North America. Not only did the company avoid the huge cost of purchasing additional servers and tape libraries, it has also reduced or eliminated ongoing tape-related expenses and freed up capital resources. Switching from tape backup to Avamar disk based backup also reduced the burdens on the company’s IT staff by dramatically reducing backup and recovery administration. With Avamar, backup of Windows files (75 percent of the company’s backup volume) is now 10 times faster than before and uses only 5 percent of the bandwidth previously required.“Avamar was much less expensive than our other backup and recovery options. But it also provides us faster data restores, more backup capacity, and scalability to meet future data protection needs.”Company spokesman, global industrial manufacturer
40 Before Avamar With Avamar USE CASE Fortune 20 Healthcare Supplier Backing up a VMware infrastructureBefore AvamarGrowing VMware environment struggles to meet backup windowDaily tape backup and offsite tape shipments—risky slow recoveryUnable to quickly replicate data through WAN for disaster recoveryWith AvamarGlobal deduplication effective within and across VMDK filesMore than 70% reduction in first backup and average of 99.7% thereafterCompared to traditional alternatives, testing showed:Avamar moved 20% of the data that Symantec PureDisk movedAvamar moved 190% less data than traditional tape backup softwareOPTIONAL SLIDEA data protection example of a VMware infrastructure with Avamar is this Fortune 20 healthcare supplier. In recent years, the company undertook a major effort to centralize IT operations and move to an enterprise-level, shared services model for managing its information infrastructure. The result was a configuration across 40 countries of 5,200 Windows and Linux servers running in a VMware virtual server environment. As the VMware environment grew, data backup and recovery became an increasingly critical issue. The company began having difficulty complying with recovery objectives and operational best practices, and was at increased risk of being unable to replicate critical information for legal inquiry or disaster recovery.Previously, the company was backing up its data to local tape once a day and transporting the tapes to an off- site location. However, this system did not support the company’s restore time objectives, as it was unable to complete a full data backup within its stated window. It was taking in excess of 22 hours to backup file and print servers, and with a success rate of only 60 percent. In addition, the prior system’s management and monitoring tools were insufficient, requiring personnel to manually scan data to determine which assets had been successfully backed up.With Avamar, a full system backup that once took 22 hours now requires about 20 minutes a day—with minimal network traffic. And the company went from a 60 percent success rate to 100 percent. According to the company, reductions and elimination in soft costs alone—including tape media and services, maintenance on the old tape area network, and required network bandwidth—have more than justified the purchase of the Avamar system.
41 Before Avamar With Avamar USE CASE Virginia Department of Motor Vehicles Remote-office/branch-office backupBefore Avamar73 remote offices, backup to local, direct-attached tape drivesNo local IT staffDaily backup required five hours per site; six hours to restore entire serverWith AvamarFour hours to back up all 73 offices through existing WAN (56k-T1) to central Avamar server45 minutes to restore entire servers; files restored in secondsCentralized management and controlOPTIONAL SLIDEAn example of remote-office data protection with Avamar is the Virginia Department of Motor Vehicles. The department had 73 remote sites and previously had local direct-attached tape drives to all the servers in all of its remote sites. The DMV had uneven IT management in all these sites and, in some cases, no local tape IT expertise. Backups took a long time to complete, and tape failures added to unreliable backup operations. Restore performance was not very good either—it took six hours to restore a server. For disaster recovery, the DMV was shipping the tapes offsite through a courier, which carried a tremendous risk of theft or loss. In this situation, Avamar was able to completely automate data protection across all 73 remote sites. By just putting Avamar software agents on the primary remote systems, the DMV was able to back up across existing WANs to the main data center. Today, backups occur within four hours for all of the 73 sites. So, Avamar delivered dramatic backup performance improvements, and centralized and automated backup management—with offsite copies instantaneously. Restore time is now 45 minutes for an entire server and just seconds for a file. Everything is centrally managed, and Avamar dramatically reduced the data protection cost and risk across the entire environment.Note to Presenter: For additional information about the Virginia Department of Motor Vehicles, refer to the complete customer profile on EMC.com: avamar-cp-ldv.pdf.“Avamar enabled us to reduce administrative support requirements by 80%, reduce backup windows by 90%, and recover lost files and servers in minutes rather than hours.”Mike DePhillip, Backup Administrator, Virginia DMV

To accommodate its expanding business, Corporate Express had to continually install new physical servers. This increased administration costs and resource requirements, placed greater pressure on IT staff, and increased power and cooling requirements at the company’s data centers. In 2006, the company launched an initiative to further expand the virtualization of its server environment using VMware products. The company aimed to virtualize 80 percent of its servers to reduce costs and improve the efficiency and availability of resources. The company soon discovered its storage could not adequately match its virtualization platform. The traditional backup solution that was in place was causing pain in terms of storage management, infrastructure costs and wasted people time. And compounding these issues were escalating maintenance and licensing costs.Since employing Avamar, Corporate Express has reduced the amount of data backed up on a daily basis from 1.5 TB to 1.5 GB. Non-disk based data backups now take 30 minutes, compared to six hours in the past. Full backups can be completed in five hours instead of nine.Corporate Express has increased the number of Avamar nodes from four (two production and two disaster recovery) to 12 (six production and six disaster recovery), reflecting its confidence in the software’s capabilities.Note to Presenter: For additional information about Corporate Express, refer to the complete customer profile on EMC.com:“We were blown away by the simplicity of the management interface and the comprehensive capabilities offered by Avamar.

A highly decentralized organization, this global pharmaceutical company also has decentralized IT operations. With more than 250 sites and 100,000 employees scattered across the globe, developing and deploying a coherent IT strategy is a huge challenge. To help, the company classifies its IT customer base into two categories: enterprise-level data centers and smaller offices. In the smaller sites, one or two IT people do everything from troubleshooting computer problems to signing for FedEx packages. Adding cumbersome data backup and recovery on top of their regular tasks overextended them even further; and the lack of consistent IT infrastructure compounded the problem. For example, a typical local office might have seven to 10 servers hosting different types of applications. The company wanted to reduce the capital and operational costs association with hosting these applications.To increase operational efficiency and consistency and improve protection of critical data at its smaller offices, the company set out to create a standardized small office “virtual application pact” to be hosted on shared services and a common IT infrastructure. The virtual application pack is based on VMware technology and six applications: Microsoft Exchange, Active Directory, SMS, antivirus, file and print services, and Avamar Virtual Edition for VMware.Avamar stood out to the company because it had minimal impact on the company’s WAN and could be deployed on VMware as a virtual appliance. The company eliminated tape storage, reducing IT expenditures; it no longer needs to purchase tape libraries, tape drives, and backup software license, or pay fees to ship and store tapes off site. And local IT personnel save time because they no longer have to swap out tapes and upgrade backup software, not to mention deal with cumbersome data recovery from tape or tape failure. Backup of a typical site’s Microsoft Exchange environment that used to take one hour now takes 15 minutes—75 percent less time. Backup of file and print servers used to take five and a half hours, now the process takes only 11 minutes. Furthermore, in the past, backup was typically the biggest resource hog for these sites, but with Avamar, backup has minimal impact on the LAN.With Avamar, the time required for replicated data to be safely offsite for disaster recovery purposes has been reduced as well. Previously the total process took six and a half hours for a typical Exchange or file server backup. With Avamar, backup and WAN-based replication the file server data is safely offsite within 10 minutes of being backed up. Less data to backup also translates into dramatically reduced storage hardware requirements. For example, at one site, backing up 3.4 TB of data used to take close to 4 TB of space (including incremental and full backups), now it takes only 500 GB—an 85 percent reduction.Note to Presenter: For additional information about this global pharmaceutical company, refer to the complete customer profile on EMC.com:“When we compared the total cost of ownership of EMC Avamar to that of traditional backup, we found that Avamar cost less yet provides exponentially better data protection and service levels.”Head of Storage Services Global pharmceutical company
