16. So … How does this work with VMware? Confidential

17. Backing Up VMware to Data Domain Confidential

18. “…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 Confidential

19. Retention/ Restore Backup Replication DR Data Domain: Dedupe Simplified Backup/mediaserver • High-speed, inline deduplication storage; disk target for nearline applications • Any leading backup software, archive apps, or custom nearline use • All data types: structured and file • Any fabric: NFS / CIFS / NDMP via Ethernet, or VTL via Fibre Channel • Disk storage: Internal, or gateway to SAN array • One dedupe infrastructure: remote office, datacenter with inline replication Archive to tape As required Offsite Disaster Recovery Storage ‘Drag&Drop’ Archiving Offsite Disaster Recovery Storage WAN Onsite Retention Storage Onsite Retention Storage Clients Server Primary storage Archive Application Server Data Domain Archive Confidential

20. 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 Confidential

21. 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 Confidential
