Solution trade-offs: • Full snapshot-based recovery - single file recovery only on Windows file system backups. • Distinctly separate proxy server required at additional cost - requires additional storage for copy of snapshots. • Backup application integrations such as Oracle, SQL, Exchange, etc., cannot be used with VCB. • VLS cannot deduplicate NetBackup VCB with FlashBackup data type yet which is used for single file restore from a VM image backup. Other information: After snapshot has been copied to proxy and backed up , it is deleted from the primary storage array where it was first taken. Further enhancements possible by providing multi site disaster recovery by using low bandwidth replication on HP VLS devices. Larger VMWare Environment with ESX4 and HP Data Protector ZDB IR Integration with VMWare Consolidated Backup Company requirements: Large VMWare environment, high throughput required to meet backup window (Fibre Channel). High SLAs require "Instant Recovery." Requirement for online application backups using techniques such as HP Zero Downtime backup. Common backup solution required for VMWare and other SAN host in the company's infrastructure. Room for growth, and more backup data online (for SLA) dictates need for deduplication. Solution: HP VLS9000 with deduplication plus HP Data Protector ZDB implementation for SQL, Exchange and Oracle. Caveats: Limited to arrays that support DP ZDB IR - XP, EVA and LHN (future). ISVs: HP Data Protector and Symantec Netbackup only at this time fully tested by HP. Device configuration highlights: Configure different virtual libraries for SQL, Exchange, Oracle snapshot backups. Backup application configuration highlights: Configuring Zero Downtime Backup within Data Protector and Symantec Netbackup requires some additional scripting work.
