Backing Up VMware to Data Domain

Confidential22

“…is he still talking..?” - Summary Concepts

Data Domain enables NAS, (CIFS, NFS) NDMP & VTL backup targets for all virtualized applications

• Drops into existing enterprise backup architectures• Works with Virtualized and Non-Virtualized environments• In 80/20 data centers, centralized capacity optimization provides single

instance store across all applications and systems, virtual or actual

Back-up VMs to DDR with agent, or service console level• Choose to place an agent on critical VMs for file level restore• Choose to place an agent on the service console as well• Back-up all to same DDRs and watch compression happen

Consolidated back-ups sent from proxy to DDR• If you prefer an agent free virtual machine…

Global Rule: all data is compared to all other data in the DDR

Replicate all or some to anywhere, whenever, and back • DR, test, development, virtual application migration

Summary: Key Attributes

Easily Integrates with Existing Infrastructure No rip/replace

Retention: Deduplication for Nearline Applications Store more backups and archived data in smaller footprint

Recovery: Data Invulnerability Architecture Trust but verify – hope is not a strategy

Replication: WAN efficient True DR Lowers cost of WAN Improves SLAs

Confidential26

Summary: Simplifying Deduplication Storage

Lower TCO Much lower cost for disk-based retention Lower operational costs, smaller foot print Neutral to price of tape automation Low bandwidth for replication, DR

Faster Handles variable streams smoothly, unlike tape Better SLAs: Random access to restores and archives

Secure Designed as store of last resort No tapes on a truck

Simple Set it and forget it Any backup or archive software, any storage fabric, all data types
