“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

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.”
