Purpose: Grabber – no one is satisfied with their backup. Dell’s contention: Match backup to business is the answer
Today, backup and recovery is a suboptimized activity. Despite numerous technological advances, data protection remains a daunting, often error-prone activity. Much of this can be blamed on the state of the current tools for backup. The challenges are many: Cumbersome include/exclude lists; onerous setup, configuration and ongoing management challenges; poor visibility into what data is actually changed and in need of backup versus a portion of a file or application that has been modified, moved, renamed or copied; numerous point products and even discrete backup techniques within a single product. While backup/recovery solutions certainly have a great deal of room for improvement, it is also the case that organizations have yet to fully embrace and deploy available data protection approaches and techniques that, in some instances, have been available for years. Incremental forever, synthetic and virtual full backups are now offered by several vendors and are robust enough for use. Disk-to-disk-to-tape backup (D2D2T), while a marketing slogan for years, is now a reality for most products, and is deployed by many companies. Client- and target-side data de-duplication solutions are offered by over a dozen providers. The ability to do image-based snapshots with individual file-level cataloging and restoration has been possible for quite some time, as well. New capabilities take time, often three to five years, to gain widespread adoption, as most organizations are risk-averse.

How much is your data growing while your backup window shrinks?
Are your RPO/RTO objectives being met?
Has your data protection strategy adapted to your virtualization strategy?
What is your legacy data protection solution costing; dollars and man hours?
How long would it take you to recover from a large failure?
Is it time for a change?

4. The Dell backup & recovery design tenets
Match requirements to the value of your data
Flexible, application aware solutions for physical and virtual
Backup in minutes, restore in seconds
Backup and business continuity from one vendor
Optimize storage capacity and utilization
Dell’s data protection mission is to protect all of a company’s data assets and applications, Simply put:
Everything; Every Time; On Time.
This means our products are designed to protect all types of information assets, from unstructured data residing on networked storage devices; to mission critical applications that are essential to daily operations regardless of the environment- physical, virtual or in the cloud.
With many companies running 24 by 7 operations; our products help administrators reduce or even eliminate their backup windows. In addition the ability to restore data quickly by providing access to that data in under a minute is often a requirement, especially for mission critical applications.
What this means to administrators is that Dell’s data protection solutions can help them reduce the costs associated with application downtime by providing the tools needed to manage their service level agreements in accordance with the company’s business objectives. Dell data protection solutions also help control the IT budget by optimizing storage utilization as a businesses storage capacity needs grow.
In IT- time is everything!
Reduce complexity, slash costs, and eliminate data loss

5. Data growth is the #1 data center infrastructure challenge today
With continued growth in unstructured data, file-based storage is one of the most critical drivers of storage1
Fueled by:
Newer applications
Virtualization
Electronic document stores
Document sharing
Web 2.0 technologies
Retention of digital records
Purpose of this slide: Explore customer storage and data management pain points
Talking points:
The data profile in today’s organizations is changing. While small, random access file and transaction data was the key component of storage within the organization in the past, over the last decade, given the rise of the web and more sophisticated high-performance applications, unstructured data in the form of large files is overtaking structured data. Why is this important? Structured means small bits of data have been organized into rows and columns so they can be retrieved by a user based upon a question, or query, that the user presents. Unstructured data is presented as whole based upon the organization of a file system or application.
Is your data an asset or a burden? With the explosion of data and the proliferation of devices that create, access, and store data, how do you find all of your data and how do you get control of it? Without knowing the importance of the data how do you decide what data to keep and where to keep it to meet your various needs? And, even assuming you can answer these questions, how do you provide data to key stakeholders so they can take decisive action? No wonder unstructured data growth was identified as a challenge for data storage in a recent IDC study (IDC – Structured Versus Unstructured Data: the Balance of Power Continues to Shift – Mary 2014).
The explosion of data in organizations – and its continued exponential growth – make storage a critical element that organizations must not fail to address in their IT strategy, while on the path to Efficient IT.

6. This growth creates data management challenges
What customer are experiencing
Backup
Inability to meet RPO (Recovery Point Objectives)
Increasing exposure to risk of data loss
Slow backups impact production systems
Multiple backup systems to support physical and virtual servers
Tape management
Expensive maintenance of media and environment
Backing up redundant data continuously increases storage costs
Disk management
Growth of backup data outstripping backup storage capacity
Not enough personnel to coordinate management of backup applications with backup storage systems
Restore
Speed and reliability of meeting RTO (Recovery Time Objectives)
Restore failures resulting in production downtime
Disaster recovery
Data replication requirements outstripping available bandwidth
Need to protect data at remote and branch offices
Management of tape media getting expensive
Not economical to replicate full copies of data offsite
Administration
Track failed backups
Monitor health of the system/media
The growth of all data – both structured and unstructured creates multiple challenges for companies of all sizes – from Small-Medium Businesses to Large Enterprises and Public organizations:
Backup – failing to meet backup windows or the inability to meet Recovery Point Objectives (desire to recover data to a specific point – i.e. last incremental update or change) will put businesses at risk. Slow backups that aren’t complete within allocated time periods also run the risk of depleting CPU resources needed to be at peak performance when production systems are active. And finally, the rise of virtualization has made backups of multiple VMs as well as physical servers a complex task.
Tape management – for those firms still backing up to tape systems, the inability to maintain the media and recover data in a timely fashion is stressful. Also, although tape systems are cheaper than disk, the increase in data volumes finds continual spending for tape media to backup the same information over and over again an expensive proposition.
Disk management - here simply put, growth adversely affects overall backup disk capacity and IT resources…. Companies are increasingly turning to technologies such as deduplication to help keep the growth of disk media in check with the rise in backup data volumes. In addition, companies don’t want to have to constantly monitor their backup environment to see application version levels are in synch and if backup jobs aren’t exceeding the capacities of their storage systems.
Restore – backup is no good without the ability to restore data within the time period expected by the business. However, all too often data isn’t recoverable quickly enough to meet the demands of business. And often, IT staff don’t have the proper time to test data recoverability until disaster strikes.
For a disaster recovery plan to succeed their needs to be enough bandwidth to replicate data back to the central site from the recovery site. But bandwidth is expensive so it makes sense to keep the amount of data replicated to a DR site to a minimum. In addition, protecting data at remote or branch offices becomes an expensive burden as data volumes grow.

During this training we’ll cover why and how the use of the Dell DR series can help alleviate these data protection challenges. Many of Dell’s DR customers continue to use tape – just now they’re using it as an archive for long-term retention of data. And disk to disk to tape type environments can certainly utilize the DR Appliance as a disk staging area also. You can store recent backups – typically 2 or 3 months on the DR Appliance so that you have the advantage of rapid restores and the increased protection of the deduplicated and compressed environment. Whenever you need to backup to tape, you simply use the backup server to read the data from the DR6000 and write out to tape to meet long-term data retention requirements.

Data protection is more than just backups. It involves all aspects of information technology working together to deliver the right service levels that account for system availability, recovery point and recovery time objectives, as well as disaster recovery plans. A “one size fits all” approach will result in some applications being over-protected while others are under-protected. This is not efficient and could even lead to data loss. Dell has a complete portfolio of data protection solutions including primary storage, backup servers, tape and disk backup targets, software and services that can help our customers balance the cost of protection with the risk of data loss and service interruption.
Specifically, the growth rate of data and the need to recover data quickly has meant that most companies must use more than one set of products to protect information. After taking the time to classify data based on its criticality to the organization including recovery time and point objectives, IT administrators can match the technology required to meet the data protection and budget objectives with different tiers of data at different stages of the data lifecycle. For example, to meet the need to protect mission critical applications where recovery times are measured in seconds, the replication and snapshots features of Dell’s EqualLogic and Compellent storage product families maintain continuous access to data.
And although host-based snapshots are useful, they don’t provide a long-term disaster recovery solution. Therefore, Dell offers solutions to balance cost with availability that include AppAssure software and DL4000 backup appliance that use a variety of recovery techniques and continuous image-level snapshots to provide near Continuous Data Protection (CDP). The Dell data protection portfolio also includes software solutions, NetVault Backup and vRanger, protecting physical and virtual servers, PowerVault MD1200 expansion shelves for backup storage capacity, the DR Series of Purpose Built Backup Appliances and the PowerVault tape systems used to protect data for long-term retention.
In this presentation we’ll cover the DR series in depth and explain how it fits into the larger set of products offered by Dell to protect and recover data as well as how the deduplication functionality of the DR series is one of the cornerstones of our strategy to help our customers manage their information.

11. Customers increasing their use of deduplication appliances
In light of the factors mentioned in the previous slide, it’s no wonder that increasingly companies are turning to data deduplication target appliances and software-based deduplication to help cut down on the volume of data backed up and replicated as seen in this set of responses to an Information Week 2013 Backup survey of 502 technology professionals.

12. Growth in the deduplication appliance market reflects this growing need to reduce data
PBBA Worldwide Capacity forecast (IDC); Revenue is forecast to be $5.7B by 2018
The growth of deduplication purpose built backup devices is reflected in this forecast from IDC’s March 2014 Market Tracker report. In fact in just the last quarter of 2013 more than 500K TB of PBBA capacity was shipped worldwide – a 8.0% Compound Annual Growth Rate.
The total worldwide PBBA market for the full year 2013 posted a 9.4% revenue increase totaling nearly $3.1 billion. Total worldwide PBBA capacity shipped for Q42013 reached 509,067 terabytes, growing 8.0% year over year.
According to Robert Amatruda of IDC, “(this PBBA market) growth outpaces the worldwide external disk array and the data protection and recovery software markets”

13. Deduplication eliminates redundant copies of data
What is deduplication?
Deduplication eliminates redundant copies of data
by leveraging pointers to point duplicate files or
blocks to a single object
Deduplication can decrease disk capacity requirements
by up to 98% and decrease bandwidth requirements for data transfer by up to 50 times.
Based on the Enterprise Server Group report “Deduplicated Backup for the Enterprise” published December Actual results will vary with data type, change rates, retention period and back-up methodologies.
What is de-duplication? As a technology de-duplication is about reducing and or eliminating redundant pieces of data.
So let’s take a look at the three different key types that we mentioned, source, server and target based deduplication.

14. Types of deduplicationB C D E

Most processor intensive
One way to do deduplication can be through single instancing – Single Instance Storage. An example of single instance de-duplication is when you have an ,– that might go to 50 people and it might has a PowerPoint attachment. A single instance dedupe engine can maintain only one copy of that attachment or one of that instance. These are typically done at the source or the application level of de-duplication.
You can also do de-duplication at a backup server. Many backup applications that we support have the ability to do this file level type de-duplication. This has the advantage of reducing the data that flows from the backup server and its backup appliance, however this is very CPU intensive.
What the DR Series does is it deduplicates data at the target. We believe this is the most efficient place to process the data because it does not put a workload either on the application server or on the backup server. It allows for the deduplication to happen inline as the data is flowing directly into the DR appliance. Additionally this tremendously affects replication by reducing the chunks of data that you’re transmitting across a LAN or a WAN for a Disaster Recovery solution.. This can truly reduce the bandwidth requirements by up to 98 percent without having to send the same thing over and over as may occur for multiple servers and multiple types of backup.

Archive older data to disk or tape for long-term retention
The rise of virtualization has been a major factor convincing companies of all sizes to consider the use of deduplication. As the quantity of data – particularly files that are less than 90 days old – grows larger and more and more VMs need backing up, deduplication is being deployed in both software and hardware to help manage the growth. As you can see from the graph on the left, the longer deduplication is in use the greater the results – esp. since most production data stores have duplicate data.
Deduplication also benefits the overall IT environment since it helps to relieve the congestion in a network when trying to replicate backup jobs – only the changed blocks of data are replication from one site to the DR site.

Performing backup’s of a companies file and application servers represents the ideal set of use cases for a Dell DR data deduplication appliance. This is true for two reasons:
First the DR appliance has been optimized for large sequential write operations such as those performed during routine backups, and:
Secondly, backup data consists of a lot of repetitive sets of data. If you think about it the operating system and application system files do not change very often. And as the amount of data you protect continues the grow there are always sets of static files that while they need to be protected, just do not get changed frequently or even at all.
For these reasons, the more often you back up the same set of machines and the longer you retain the data from those backups, the better your storage savings will be when using the DR appliance as a backup to disk target. Now let’s look at a few of the most common data protection use cases.

Data Integrity Features
Backups are typically used when all available means to recover data on the production systems have failed or are not feasible. Backups are not verified by users on a daily basis, so it is essential that backup systems treat
data protection as the most important task.
The DR Series has several hardware and software features that together deliver unsurpassed levels of data protection. These features are:
 Software
o Continuous data verification: Existing data is read back periodically and checksums compared to verify data integrity.
 Hardware
o NVRAM (non-volatile RAM): Ensures data is protected in case of power loss.
o Surface Scans: These are triggered in the event of hardware faults to report and/or correct data inconsistencies.
o RAID6: All data on the DR series is protected by disks using RAID6 with a hot spare disk. This RAID level protects data against as many as two simultaneous drive failures.
Continuous data verification and surface scans are performed in the background so as to not disrupt core backup and deduplication activities.
DR Series has built in data protection safeguards in both hardware and software to verify backup integrity
Early Write Verify: Data is read back after ingest to check against silent corruption of both data and metadata
Surface scans trigger off corruption due to faulty hardware
Continuous Data Verification: Existing data is read back periodically and checksums compared to verify data integrity

Some of the featured highlights of the DR6000 are:
It’s built on the Dell 12G hardware platform featuring a PowerEdge R720 server with dual Intel Xeon processors and 48GBs of memory installed to ensure high performance.
Like the DR4100, the DR6000 has built in inline deduplication and data compression technology that dramatically reduces the overall cost of storing backup data.
DR appliances can replicate backup data in a deduped, compressed, and optionally encrypted format. This helps to protect against major disasters by enabling a reliable, secure, and efficient way of storing a copy of backup sets in a remote site.
A hallmark feature of the DR appliance line has always been its all-inclusive software licensing model. There is no need to buy additional licenses to use advanced features such as replication and data compression.
The DR6000 boosts Rapid Data Access ingest performance to an impressive 22TB per hour which helps reduce the size of backup windows when using Dell NetVault Backup and vRanger backup solutions.
The DR6000 is certified with all the major backup software applications in the market including Dell’s NetVault Backup, AppAssure and vRanger. Support is also provided for most popular third party solutions including Backup Exec, NetBackup, CommVault, Networker, and Veeam, to name just a few.
The DR6000 includes Advanced Data Protection safeguards in both the software and hardware layer’s to ensure data integrity. Software modules scrub the data periodically and compare it with checksums stored as data was written to detect any data corruption and the 12 data drives in the controller and each expansion shelf are configured in a RAID6 configuration allowing the system to remain operational after multiple drive failures. There is also a NVRAM card in the system which protects in flight data in the event of a power loss.
And now the same high 22TB performance provided when using a DR6000 with Dell branded solutions that support Rapid Data Access is available for a wider range of backup applications that support OST, or the more widely used NFS and CIFS standard network protocols for accessing their disk backup targets.
The DR6000 base controller module is available in four flexible capacity points– from 9TB up to 36TB.

Here we see the maximum configuration supported by the DR6000 appliance. While we already discussed most of this information and how it compares to the DR4100 appliance, this image reviews the DR6000’s key performance, scaling and capacity improvements in a concise snapshot that makes it easier to recall these metrics during discussions with customers.
In addition to more than a 2x improvement in total usable capacity; the DR6000 doubles the number of simultaneous replication streams and containers supported as well as how many clients and connections can be made to a single appliance. Another metric you should become familiar with is the maximum number of files supported.
As you can see this is dependent on the capacity of the drives used with 64 million files being supported on all drive types except the 1TB drives that support 32 million. It should be noted that a file on a DR appliance does not necessarily equate to a single file from a source machine being protected. This is totally dependent on the backup software in use and the streams from most backup jobs will contain many end user files within the stream.

The DR6000 base modules are available in four capacity points from 9TBs up to 36TBs. The capacity of a single appliance can be configured to meet varied customer needs by adding additional storage shelves.
With the DR6000 customers can add from one to four PowerVault MD1200 storage enclosures with different capacity drives to provide-
Flexible expansion options to meet varied customer requirements. Each MD1200 enclosure contains 12 drives in a RAID 6 configuration for improved resiliency plus a global hot spare. The drives used in each expansion shelf must be of the same type and capacity as the drives in the base unit. Like the base models, external expansion shelves start at 9TB after RAID reserves using the 1TB drives and capacity increases to 36TBs using the available 4 TB drives.
More importantly, just like with the DR4100 expansion shelves can be added at anytime allowing customers to defer buying additional capacity until their requirements grow.
With the DR6000 all models including the 9TB base version support the ability to add additional capacity. This allows customers the freedom to start with the model that best fits their current needs and grow their DR6000 capacity as and when needed to support future data growth.
Note that as before a capacity license is required to add expansion shelves to a DR6000 appliance.

Market research found that, of respondents currently using data deduplication technology, around 30% said they have experienced a less than 10 X reduction in capacity requirements; around 50% report a 10 X to 20 X reduction, and around 20% report reductions ranging from 21 X to 90X. Factors affecting dedupe ratio are – Data type, Change rate, Backup schedule (Full vs Incremental), and Retention period
A question that comes up quite frequently from customers is “what will be my data deduplication savings”?
The simple answer is, it depends on a variety of factors. The most important considerations being:
The data type, for example databases, Microsoft Office files, image based graphic files or entire virtual machines. Each type of data typically dedupes differently than the others, backups of machines with databases or unstructured data like MS Office files will deduplicate better than backups containing scientific data or a patient’s x-ray images.
The rate of change in the environment in addition to the type and frequency of each backup is another important consideration. For example, a full backup often contains more duplicate data than an incremental that only backs up data that has been changed since a prior backup was taken.
The frequency of the backup runs also influences the effective ratio especially with full backup jobs. Depending on the rate of data change, a full backup will contain a high percentage of redundant data as the same information is backed up over and over again such as the operating system’s files which do not get updated all that frequently.
The retention periods used for each backup operation is one of the greatest factors influencing the deduplication ratio observed by a customer. In general dedupe ratios improve over time as illustrated in this graphic. Note how the estimated deduplication ratio increases month over month. This is because as old backup data is retained and the source machines are backed up over and over again, the chances of finding duplicate data segments on the target DR appliance increases.
To get the best possible rate of data reduction, it’s important that customers retain backup data for at least one month, preferably longer, and use the same DR appliance target for each client when running multiple backup jobs and more than one DR device target is available. The ability to store backup data on disk for longer periods of time is a key benefit of DR appliances because longer retention periods increase the chance of a faster recovery when needed if the data is being restored from disk instead of tape.

Now when these physical or virtual servers need to act in a disaster recovery scenario, all the same interactions occur. In this example, we see two different DR appliances being used to store the local backups at two different locations.
To provide a redundant copy for use if one location is completely down, container based replication has been set up to replicate data between the two appliances. The DR appliances provide all of the replication processes transparently to the backup and application servers. It's key to note that the replicated data is sent in its deduped state and the files don't have to be rehydrated for replication. The data is also compressed and optionally encrypted.

When you extend the disaster recovery solutions to include remote or branch office protection, the DR Appliance provides some very excellent advantages.
You have bidirectional 1:1 or many to 1 replication. With the new release of the DR6000 we now support 64:1 fan in replication. Each unit replicates only the changed blocks and again in a compressed and optimized manner. Replication is asynchronous and can be configured on a container basis to be scheduled or throttled or paused depending on particular WAN conditions that might exist in this distributed environment
Deduplicated replication is cool, and disks might be getting cheaper, but bandwidth isn’t. This configuration also enables tapeless backup of remote offices where there is no IT staff to maintain the overhead of traditional tape backup environments

One of the key benefits of using a RDA device interface that is enabled to provide native replication is the ability to minimize network traffic and reduce the number of hops required for both the initial backup and subsequent backup saveset data copy operations.
As shown here, the NetVault Backup Server will initiate the backup job and provide a connection handle for the target DR Appliance to the client where the job is to run. The control path is used to setup the backup operation, monitor progress and catalogue the results of the backup job.
Depending on the client platforms supported by the RDA interface, the backup data will generally flow directly between each client and the primary DR target instance. When using RDA enabled DR Appliance device targets, direct data paths are only supported from clients running supported RDA interface operating systems so in some cases the data may need to be routed through a NVBU Server or SmartClient that is running on a supported operating platform. Check the NVBU documentation for RDA interface support details.
Once the backups have completed, secondary copies of the savesets can be created using the replication functions provided by the RDA enabled DR Appliance. In this case, the RAS service on the NV Backup Server will manage the replication of the backup saveset but the data path will be directly between the primary and target DR Appliance devices. This moves the overhead off of NetVault Backup and the client machines directly to the appliances.

Rapid NFS and Rapid CIFS are network file system accelerators that like Rapid Data Access, only send unique data over the wire which results in significant savings in terms of bandwidth consumed during the backup and a reduction in the time it takes for the backup to complete.
The Rapid NFS/Rapid CIFS plugins can be installed on either the application server itself for true client side dedupe or the backup software’s media server depending on where customers want to incur the deduplication overhead and the supported operating platforms. For example, in most cases the best results are obtained by installing the plug-in directly on the client. This ensures that only unique data blocks are sent over the wire to the DR6000 target.
When the application server is already overloaded or is running an unsupported operating platform, you can choose to have the data deduplication performed on a local media server that performs the data chunking and hash computations before sending the unique blocks on to the DR6000.
With the initial release of the DR6000, the Rapid NFS/Rapid CIFS network backup accelerator plug-ins are supported for installation on CommVault Simpana; EMC NetWorker; and IBM Tivoli Storage Manager (TSM) clients or media servers running on supported operating systems.
Also note that the DR6000 can service up to 64 multiple and concurrent CIFS/NFS backup streams from media servers.
Rapid NFS and CIFS features are only available on a DR6000 running DR OS version 3 and above. (A future release of DR OS is being planned to extend this capability to DR4100 appliances, as well.)
Once the data is safely stored on the initial DR6000 it may be replicated to another remote DR appliance for disaster protection using the appliances built-in container level replication function. Having the flexibility to control where the data deduplication algorithms are run is a key backup performance tuning parameter. With DR OS 3.0 you can control where this operation is performed- on the application server, backup software, media server or the DR6000 appliance. In some environments a combination of all of these locations may be required to satisfy the customer’s performance requirements without impacting production workloads during the backup window.

32. Global View – Multiple DR Management added in DR OS.30
Global View – is a new feature for the DR series added with the Operating System release. It lets customers manage multiple DRs with single GUI instance. It’s important to note that:
Maximum number of nodes that can be part of global view is 64
It only works with DR appliances connected to Active Directory
The browsers supported are:
Internet Explorer 9.0 and 10.0
Firefox 23 or higher
Chrome 29 or higher
Here is a screen shot from a Global View dashboard that is being used to manage multiple DR appliances. The left hand side navigation bar now includes a selection for Global View in addition to the normal individual unit specific management options. There is a Global View Summary across the top that provides key metrics for all appliances added to this instance of the Global View.
The main center window of the Global View dashboard will display rolled-up statistics for each participating member and will update them every 15 seconds using a fixed periodic refresh rate. From this dashboard is easy to check the status of every DR Appliance in the global view and then drill down into a specific appliance as needed to address critical alerts, check its configuration and add new work flows.

Dell AppAssure software provides for very granular recovery point selection by performing a series of snapshots on a regular basis.
Over time as new data is added to the AppAssure repository it will begin to require larger storage pools. However, since the most frequent data recoveries are performed within the first few months of the backup, it’s a good idea to groom the AppAssure repository by moving aged data to an alternate location freeing up space for new AppAssure snapshots.
Using a DR appliance as the archive target is an excellent choice as it able to further reduce the space needed to hold the data by applying its own deduplication and data compression algorithms to the AppAssure data as it is written to the appliance.
To archive aged data from the AppAssure core to the DR appliance
1. set up an archive policy that moves older point in time backup images from AppAssure to a DR container.
2. When the policies execute, data meeting the archive criteria will be assembled on each AppAssure Core and written to the DR appliance.
3. The DR appliance will then de-duplicate and compress the data as it is being stored in its data repository.
4. If another DR target is available, the archived snapshots can be replicated to that device to provide an additional copy for added protection and to address disaster recovery concerns.
AppAssure archive support is available on both DR4100’s and DR6000’s running DR OS version 3.0 or higher.

Dell DR6000 / DR4100 X
OST
DR Appliances have supported the Symantec Open Storage Technology or OST backup API since the series started with the DR4000 in order to provide high speed backup data ingest and recovery operations when a DR appliance is used with Symantec’s data protection solutions. When using the OST APIs Dell labs tests showed excellent ingest rates of 5.9TBs an hour on a DR4100 and up to 22TBs an hour on the new DR6000.
The OST API ensures that Symantec’s data management products are performing optimized deduplication of backup data on their clients or media servers and only transmitting unique data blocks to the DR. Through the OST interface the backup software is in control and fully aware of replication processes performed by the DR Appliances and again only unique data is replicated from one DR device to another.
Now with DR OS version 3, a new capability has been added to the DR appliances OST Plug-in- Virtual Synthetic Backup support. A virtual synthetic backup, also known as incremental forever or consolidated backup, is a Symantec NetBackup feature that creates periodic full backup copies without having to rescan and backup all data on the source machine. This is the way it works with Dell DR appliances:
First initial full backups are run on the client machine and the data is sent to the NetBackup Server (or one of its media servers) where the data deduplication is performed -- any unique data blocks not already in the DR repository are sent to the appliance to complete the operation.
Then nightly incremental backups are performed and the data follows the same processing path with the unique blocks from the incremental backups being sent to the DR appliance.
On a regular interval (i.e. weekly) the backup server sends a list of the data blocks required to create a new full backup copy using the block maps from the initial full and the subsequent incremental backups. The resultant backup copy represents a full backup copy of the client’s data as of the date and time of the last incremental backup.
The benefits of this approach are that after the last incremental backup has been performed, no data needs to be transferred from the client to the DR Appliance to create a new full backup copy for that client. The processing power of the Dell DR appliance is used to create these backups without having to move large amounts of data over the network or adding additional overhead to the client machine or one of the backup products media servers. The entire process takes place on the DR Appliance and once completed the new backup copy can serve as the baseline for future incremental backups. Virtual Synthetic Backup’s reduce the duration of the weekly full backup window and the network bandwidth utilized.

35. Key DR Series system differentiators
Total Cost of Ownership
Deduplication/compression can reduce backup storage costs to as low as $.17/GB
Inclusive licensing: replication and OST or RDA licenses included as well as future software upgrades
Reduce OPEX versus traditional disk and tape - power, cooling, management, etc.
More economical Disaster Recovery solution compared to standard disk and tape 1
Performance and Functionality
Fast backups and restores
Reduce backup storage footprint by 15X or more1
Reliable backup and restores compared to standard disk and tape
Increase Disaster Recovery readiness by reducing WAN traffic more than 20X 2
Here’s a summary of the DR Series highlights…. Including the TCO, peformance/funcationality and inclusive licensing aspects.
TCO: DR appliances help control customer costs by reducing the amount of space required to store a customer’s backup data on disk for longer retention periods. The all inclusive licensing model helps manage initial acquisition costs by providing advanced feature sets in the base price of every DR Appliance. Also, customer’s will enjoy lower operating expenses when compared to traditional disk and tape backup targets due to reduced power and cooling requirements.
The technical advantages of adding DR Appliances to their backup strategy are equally impressive. DR’s offer faster, more reliable backup and restore performance when compared to tape that is sure to get the attention of backup administrator’s. The data deduplication function in DR Appliance’s provide on average a 15x or better reduction in the storage footprint required for backup data and the optimized replication feature accounts for a 20x reduction in network traffic when replicating between appliances over a wide area network.
Performance and functionality: Much of the DR’s performance and reliability advantages can be attributed to two sets of technologies- increased performance and data throughput comes from the DR appliances extensive set of accelerators such as OST, RDA and the newly announced Rapid CIFS and Rapid NFS plug-ins we will discuss shortly. Improved data reliability is achieved through the advanced data protection features we just discussed when reviewing the DR appliances hardware and software specifications.
Licensing: Finally, Dell DR Appliances help protect the customer’s investment, long term, by including all future firmware updates and allowing additional storage capacity to be easily added as their backup storage requirements grow. In addition, DR appliances leverage the key Ocarina based data deduplication technology that will be used to drive storage optimization across the Dell Data Protection portfolio. This makes DR Appliances a cornerstone of Dell’s future data protection solution strategy regardless of the data protection solution in use by the customer but ensures the best returns when combined with other Dell branded hardware and software technologies.
