• Online backup of File System and Application Data inside the VMs. Enable single object and application recovery (including point in time) • Single appliance solution for VMWare and non-VMWare hosts Solution trade-offs: Network Backups can only reach around 80 MB/sec best case. For high volumes of data this may not be fast enough to meet a fixed backup window, but VMWare backups tend to be a lot of small machines with not high volumes of application data. Other information: HP strongly recommends using the backup application to perform the copy from VLS to physical tape. Single management console for all activities and better utilization of physical media through object copy technology. Further enhancements possible by providing multi-site disaster recovery by using deduplication-enabled replication on VLS devices. VMWare Backup Environment with ESX4 and VCB-based Backups Company requirements: Mid-sized VMWare environment, wants VMWare-based snapshot backup with individual windows file-based recovery using VMWare consolidated backup (VCB) in ESX4. Company also wants single device for VMWare backups and other SAN host backups in their infrastructure. Solution: VLS9000 15 TB with deduplication (licensable feature) plus object copy to physical tape for disaster recovery. VCB snapshots created on VCB proxy server then backed up. Caveats: This is mainly a snapshot-based backup technology where complete images have to be restored. File level recovery from a file system backup is only possible with Windows. The proxy server has to have sufficient storage to store the snapshots if image-based backups are being used because the images are copied from the primary storage to the proxy server for these types of backup. ISVs: HP Data Protector and Netbackup only at this time. (Tested by HP enterprise backup solutions lab in depth.) Device configuration highlights: Separate virtual library created for each VMWare machine. Backup source is VCB proxy server with snapshot copied to it from the MSA2000 in this case. Backup application configuration highlights: Backup is a combination of VCB doing the snapshots and backup applications writing the snapshots to backup device. VCB is hardware independent hence can accommodate snapshots with all array types. 72 VLS Devices
