1. VM backup • Data Protector Integration with VMware VCB provides the first layer of protection • Provides snapshots that can be used for restoring VM • Needed only when VM configuration changes 2. Application backup • Provides the second layer that enables protection of application data • Can be performed using ZDB/IR feature of Data Protector by using HP Business Copy for EVA, XP (LHN to follow) Further enhancements possible by providing multi-site disaster recovery by using low bandwidth replication on HP VLS devices. Large Enterprise Cross-site Backup with Deduplication and Inbuilt Disaster Recovery Company requirements: Fully redundant system with automated offsite backup over extended SAN - getting data offsite immediately is the requirement. Manage data growth, keep more data online, regular archiving to tape using object copy. Solution: VLS9000 with deduplication over extended SAN. ESL library for high volume archiving. Caveats: CWDM bandwidth is the critical performance factor in this solution typically using HP Multi-Protocol Routers. ISVs: HP Data Protector, Symantec Netbackup and TSM (deduplication support) only at this time. Device configuration highlights: Normal VLS deduplication requirements - small cartridges, strict backup policy naming. Backup application configuration highlights: RMAN stream naming scripting required for best Oracle deduplication performance. Figure 33 Using VLS in Enterprise Cross Site Backup Scenarios Recovery options: Depending on retention time on the VLS, data can be recovered directly from VLS on the remote site or if that retention has expired then a copy should be archived on physical tape which is again directly available from the remote site over the extended SAN. 76 VLS Devices
