“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 2009

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

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

Client-Side Deduplication Moves Less Data
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

VMware Image-Level Backup
• Deduplication within and across VMDK files
• Changed Block Tracking (CBT) reduces backup time and minimizes recovery time
• File-level recovery from image backup (Windows)
• Flexible restore to original, existing, or new virtual machine
• Proxy server load balancing for superior throughput

Integration with VMware vCenter Server • Manage data protection and contain
virtual machine sprawl
• Browse to VMware vCenter Server through the Avamar GUI
• Auto-discover virtual machines and their associated groups
• Monitor backup/restore operations in the Activity Monitor
• View VM protection status (guest/image/none)
Single point of management for VMware backup options

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

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

Customer Case Study: Health Quest • 12+ hour backups
• 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
“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.”
