5 Data protection paradigms and architectures (especially backup and recovery) must change in order to adapt to virtualized environments. IDC s Worldwide Storage for the Virtualized Environment Taxonomy, 2009 (Doc #221325), Benjamin Woo, Laura DuBois, Noemi Greyzdorf, December

6 The VMware Backup Must Have List Must address today s issues Relieve resource contention Contain backup storage growth Enable more-effective disaster recovery Must provide business value Lower backup infrastructure costs Improve operations Reduce risk Must integrate with VMware infrastructure VMware vstorage API for Data Protection VMware vcenter Server 6

7 Deduplication Is the Key Relieve resource contention Contain backup storage growth Enable more effective disaster recovery 7

8 Client-Side Deduplication Moves Less Data VMware ESX Network B A D A C A B C B D C B 1. Divides data into sub-file variable length segments 2. Determines if segments are unique or duplicate 3. Backs up only data that is unique 4. Sends data compressed and encrypted Avamar Data Store 8

9 Avamar Deduplication backup software and system Avamar VM End-to-end, software/hardware solution Improves backup window, less network load Client-side deduplication Integrated high availability and reliability Flexible deployment options Standalone Integrated with Data Domain and NetWorker Full backups every time and one-step recovery Higher backup success rate and reliability Increased ROI, lower TCO, less risk 9

10 Avamar Is Optimized for VMware Guest-level backup Provides application consistency Image-level backup Integrated with VMware vstorage API for Data Protection and vcenter Server One-step file-level recovery from image backup Tight VMware vcenter Server integration Qualified on VCE Vblock Infrastructure Platforms in EMC test labs Deployable as a virtual appliance Avamar Virtual Edition 10

11 VMware Guest-Level Backup Avamar agents ensure application consistency Avamar agents VMware ESX Application-specific agent within each VM ensures consistent state for hot backup Deduplicates within and across virtual machines Reduces resource contention and speeds backups Provides file-level restore for Windows, Linux, and Solaris Control cost with zero-dollar agents 12

18 Integration with Data Domain High-speed, scalable Avamar backups to Data Domain systems Selectively back up and restore specific data types to a Data Domain system VMware image backup Oracle and Microsoft SQL Server, Exchange, SharePoint Easy to manage Associate Data Domain system(s) with Avamar Select the destination of backup data via policy Manage backups, restores, and replication through Avamar GUI 19

19 Solution Sizing: Variables to Consider Number of virtual machines Data size of each virtual machine Aggregate daily change rate Backup window Initial full backup and subsequent Underlying storage read performance Connectivity, drive type and I/O 20

20 Account for Process Overhead Virtual proxy server performance limits Proxy can scan rate GB/hr A proxy will only process one VM at a time VMware process Approximately 2 minutes per VM Creating snaps of a VM related to I/O of VM SCSI hot-add Enable change block tracking Additional 10% storage needed Virtual machines VMware Virtualization Layer x86 Architecture Resource Pool Physical server Proxy VM Avamar software agent Mount Storage Physical server 21

21 Example Environment Production storage volume ~ 50TB Number of VMs ~ 1000 VMs (50GB/ea) Aggregate daily change rate ~5% Multiple DRS clusters Assume an 8 hour backup window First full backup Subsequent backup 22

24 Customer Case Study: Global IT Services Firm 2 DATA CENTERS 600+ VIRTUAL MACHINES 60 NEW SERVERS PER MONTH Discovered operational issues with tape backup VM/ESX server sprawl was bloating costs and complexity Traditional backup did not align with IT strategy VMware deployment slowed until backup redesign was completed Company standardized on Avamar for VMware Saved $9M over three years = more than $3M used to fund more VMware purchases 98 percent reduction in backup data 30 percent increase in VM-to-ESX server ratio Reduced operator staff from 60 to 10 U S E C A S E 25

25 Customer Case Study: Health Quest 12+ hour backups 2 DATA CENTERS 210 VIRTUAL MACHINES BACKUP EXEC + TAPE Our weekly full backups for our virtual environment were bringing our VMware servers to a crawl. With Avamar, we don t even notice when backups run. From a TCO and management perspective, Avamar was an absolute home run. Michael Close, Sr. DBA and backup administrator, Health Quest Frequent backup failures and downtime Long and inconsistent restores Placed the VMware deployment on hold until backup issues were resolved Only Avamar could deliver Eliminated tape and saved $1M over three years 96 percent reduction in backup data Increased VM-to-ESX server ratio Improved service level agreements for backup and recovery U S E C A S E 26

26 Avamar for VMware Unlike anything else in the industry Maximize virtualization investments Support for latest VMware vstorage APIs for Data Protection Tight VMware vcenter Server integration Deduplicated guest and image level, daily full backups Shorten backup and recovery time One-step full recovery Improve bandwidth efficiency Simplify data protection management Shrink storage requirements Lower costs Scalability, high availability, and reliability Replication and disaster recovery EMC s backup and recovery solution portfolio 27
