BACKUP-TO-DISK AND RECOVERY WITH DEDUPLICATION

Backup and recovery of company data at primary sites typically places high demands on the
resources of a company’s IT department. The result is that data protection is neglected at
the smaller, remote sites even though information at these regional oces or branch oces
may be as important as that found at the primary data center. A lack of technical resources at
remote sites further complicates the problem. Even if standard backup-to-to-disk technologies
are implemented at remote sites, the data continues to sit there unless a tape DR strategy
is implemented because there is simply too much data to reasonably replicate back to a
centralized site for DR purposes.
The combination of backup-to-disk, data deduplication and remote replication solves this
problem, oering a great deal of value by dramatically reducing bandwidth requirements to
move data over the WAN from remote sites to a centralized data center. Utilizing deduplication,
bandwidth costs are significantly reduced because less data is sent over the WAN. Data is
protected much quicker than if all of the backup data was to be sent over the WAN (this could
take several hours, even several days).
Because the CommVault Simpana platform comes standard with the DL2100 , combining
CommVault Simpana Replication with the DL2100 is simply a matter of add a simple add-
on module. All replication features are administered through the same interface. CommVault
Simpana Replication supports all industry-leading applications, including Microsoft Exchange,
Microsoft SQL and Oracle. As a result, backup data can be reduced in size with deduplication so
that network-based replication can be used as an alternative to tape-based o-site archival.
For branches that require quick recovery time objectives, the PV DL2100 powered by
CommVault may be paired across geographically distributed sites to eciently replicate the
deduplicated backup pools. Each remote backup pool will oer rapid recovery at the branch
oce, while ensuring you are doubly protected with a replica copy at your central site. The
replica pool provides a constant availability copy to service DR restore needs or support the
creation of tape copies.
Unlike other disk-to-disk appliances that require their own proprietary solutions at the
centralized location, CommVault Simpana Replication supports any disk hardware. Data stored
on a DL2100 in a remote oce can be replicated back to a any centralized disk array (e.g. an
additional DL2100 is not required at the centralized site).
