1 1EMC CONFIDENTIALINTERNAL USE ONLY EMC EMEA TC Conference 2010 Supporting Our Customers Journey to the Private Cloud BRS Solutions for VMware

2 2EMC CONFIDENTIALINTERNAL USE ONLY Image vs Guest Level Backup Guest level backup: traditional backup type by using backup software agent inside VM to read and transfer data just like on physical system. Image level backup: backup is performed from ESX host by freezing VM and backing up its image. ImageGuest Backup application compatibility Limited, but increasingRequires only qualification VM system compatibility Limited to specific guest OS types and disk formats Transparent VM application compatibility LimitedTransparent, standard backup application modules can be used. Performance High to very highLow to medium Resource usage Low to mediumHigh

3 3EMC CONFIDENTIALINTERNAL USE ONLY Application vs Crash Consistency Typical image backup provides so-called crash-consistent backup. In case of restore, VM is restored to a state equal of unplanned shutdown. It does not provide application-awareness To provide application-consistent backup, application itself must be informed of backup Possible on Microsoft platform via VSS framework Generally up to backup software vendor to provide VSS integration Limited VSS integration provided by VMware starting with vSphere 4.1 Supported only for VMs running Windows 2008 Supported for limited set of applications With VSS integration, backup level reached is application-consistent, but not application-integrated For full application-integration and advanced capabilities, must use in-guest backups with appropriate application module.

4 4EMC CONFIDENTIALINTERNAL USE ONLY VCB: VMware Consolidated Backup Introduced with VMware ESX server 3.0 and still present in vSphere 4.0 Leverages VMFS snapshot technology Not stable before VCB 1.5 introduced in ESX 3.5 Latest version is VCB 1.5 Update 2 from March 2010 VMware discontinued development of VCB and existing customers are encouraged to upgrade to VADP based solution VCB is no longer present on vSphere 4.1 VCB is still supported for restore purposes even on latest vSphere versions VCB requires a separate HW proxy host VCB requires presence of VMware vCenter Converter (vConverter) vConverter version must match supported version from backup application.

5 5EMC CONFIDENTIALINTERNAL USE ONLY VADP: VMware Storage APIs for Data Protection Introduced with VMware vSphere 4.0 Leverages VMFS snapshot technology Backup flow is based on more integrated API Supports VMs based on VMware vStorage VMFS VADP cannot be used to protect pass-through disks (RDM: raw device mapped disks in physical compatibility mode) VADP cannot be used to protect network mounts (CIFS or NFS) within guest Backup solution can optionally have deeper integrated with storage arrays via VAAI: VMware vStorage APIs for Array Integration This offloads VM snapshot creation from ESX host to array itself Introduces limited application-awareness starting with vSphere 4.1 Proxy host is a VM itself. Need a separate VM proxy for each OS type (Linux or Windows)

6 6EMC CONFIDENTIALINTERNAL USE ONLY VADP vs VCB Quick Compare Unlike VCB, which requires customers to download and install a separate VADPVCB Requires additional download & install No, built into the data protection softwareYes Full virtual machine image backup Yes, single step copy – source to target Yes, with two step copy – source to VCB proxy and VCB proxy to the target Incremental virtual machine image backup Yes – using change block trackingNo File level backup Yes, both Windows and LinuxYes, Windows only Full virtual machine image restore YesYes, by using VMware Converter Incremental virtual machine image restore YesNo File level restore Yes, using restore agents CLI for image backup NoYes CLI for file backup Yes

7 7EMC CONFIDENTIALINTERNAL USE ONLY CBT: VMware VADP Change Block Tracking VADP supports optional usage of CBT CBT is disabled by default and must be enabled per VM CBT requires that VM version is 7 or higher. Environments upgrading from ESX 3.x to ESX 4.x need to upgrade each VM CBT does introduce small performance penalty on production system Not recommended for VMs with very high change rate

8 8EMC CONFIDENTIALINTERNAL USE ONLY EMC BRS Solutions for VMware NetWorker Avamar DataDomain

9 9EMC CONFIDENTIALINTERNAL USE ONLY NetWorker and VMware Protection Support for vSphere (VCB support in all current versions) Deduplication support Granular and application consistent guest level backup Off-host snapshot-based backup Granular and full image recovery with single image backup Incremental and differential file backups based on full image Licensed per physical host. Not per VM. VDAP support coming in NW 7.6 SP2 OFF-HOST IN-GUEST

10 10EMC CONFIDENTIALINTERNAL USE ONLY VMware Auto-Discovery and Visualization Auto-discovery –Automatically discover VMs –Notification of unprotected VMs Visualization –Visual map of the environment –Interactive controls to filter display –Displays relationships between NetWorker and virtual environments –Helps determine load balancing –Configure VM backups from map easy, right-click-to-launch wizard

11 11EMC CONFIDENTIALINTERNAL USE ONLY NetWorker with Data Domain Use with existing disk-based or VTL capabilities Use with DD Boost –Improved performance –Clone-controlled replication –Automated configuration –Monitoring and reporting Primary data centerRemote site Replication WAN Data Domain FILE SYSTEMS AND APPLICATIONS

12 12EMC CONFIDENTIALINTERNAL USE ONLY Benefits of Data Domain Boost Deduplication distributed to backup servers –Increases backup speed –Reduces network traffic Clone-controlled replication –Schedules replication –Catalog awareness of replicated copies Ease of use –Automated configuration –Monitoring and reporting NetWorkerData Domain DD Boost

13 13EMC CONFIDENTIALINTERNAL USE ONLY NetWorker with Avamar Supports file systems and applications Physical and virtual Manage traditional and deduplication backup –Single client or application module –Common administration –Full indexing and browse –Common recovery Primary data centerRemote site WAN Avamar FILE SYSTEMS AND APPLICATIONS Replication

14 14EMC CONFIDENTIALINTERNAL USE ONLY Avamar VMware Guest Backup No-cost Avamar agents assure application consistency Agent resides in each virtual machine Deduplicates within and across virtual machines – as if they were physical servers Reduces resource contention and speeds backups Provides file-level restore for Windows, Linux and Solaris Avamar Agents VMware ESX

15 15EMC CONFIDENTIALINTERNAL USE ONLY Avamar VMware Image Backup Avamar integration with VMware vStorage API Deduplication within and across VMDK files –Load-balancing across proxy virtual machines Change-block-tracking minimizes recovery time File level recovery from image backup Replication provides DR for backed up VMDKs Resource Pool VMware Virtualization Layer x86 Architecture Physical server Virtual Machines SAN storage Avamar server Mount = Avamar Software Agent Physical server

16 16EMC CONFIDENTIALINTERNAL USE ONLY Proxy Server Load Balancing Avamar efficiently uses available resources How does this work? 1.Avamar automatically assigns VMs backup jobs to available proxy servers using a round robin protocol 2.Backups are distributed evenly across available virtual proxy servers Benefits Automatic and transparent More efficient backups Better use of available resources Simplifies the management of virtual proxy servers Applied either globally or in groups ESX SERVER CLUSTER Storage LUNs Virtual Machines Proxy Servers Pool Avamar DRS VMware

17 17EMC CONFIDENTIALINTERNAL USE ONLY Use Cases Clear Channel Protecting ~90TBs/1200+ VMs using Avamar and VADP&CBT image backups Backup time range 3 min to 1 hour/VM Without CBT some very large VMs (750GB in size) take upwards of 6-7 hours to backup. Bank of America Protecting up 350TBs+/6000 VMs using guest backup Average backup time 6 min/VM GSK Protecting ~50TBs/1000 VMs using guest backups Average backup time 6 min/VM USAA Protecting ~75TBs/1300 VMs using guest backups Backup time range from 2 minutes to 1 hour
