Using D2D in VMWare Environments with ESX4 and VMWare Consolidated Backup

Company requirements: Mid-size VMWare environment, wants VMWare based snapshot backup
with individual windows file based recovery using VMWare consolidated backup (VCB) in ESX4.
This is the backup solution promoted by VMWare themselves. The main idea behind VCB is to offload
the workload for backup from the ESX server onto a separate proxy server giving potentially better
performance.
Solution: HP D2D with VTL FC interface and separate VCB proxy server.
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: VCB in ESX4 takes snapshots of the VMWare machines which are then presented to the proxy
server for backup so most backup applications will work when they are installed on the Proxy server.
HP has tested Data Protector and Symantec Netbackup to great depth in this area.
Device configuration highlights: Consider creating one virtual library per virtual machine (best
throughput) or one large library for all machines to share (best deduplication ratio). Consider
configuring multiple virtual libraries for different data types (office files, MSExchange Databases)
across multiple host servers to get best possible performance and deduplication ratio.
Backup application configuration highlights: Backup several streams concurrently for best performance.
Backup is a combination of VCB doing the snapshots and backup applications writing the snapshots
to a backup device. VCB is hardware independent hence can accommodate snapshots with all array
types.
