BACKUP-TO-DISK AND RECOVERY WITH DEDUPLICATION
INteGrateD taPe SuPPort For DISaSter reCoVery aND VaultING
Tape can still play a valuable role in your protection strategy when it is no longer the primary
data copy to service your recovery window. Demands for osite DR protection or selective
vaulting for compliance requirements can drive the need to seamlessly integrate tape copies
directly into your backup retention policies. The PowerVault DL2100 oers simple add-on
options to integrate the Dell PowerVault TL1000, TL4000, or ML6000 tape library directly into
the full solution. Storage policies take full advantage of backup to disk for rapid recovery, while
automatically transferring selective data copies to tape for osite protection.

The need to recover data will happen. Files are lost, viruses take down infrastructures, disk
drives fail and floods happen. Organizations that continue to rely on standard backup-to-tape
solutions as their first line of recovery are subject to lengthy and sub-standard restores. Data
may be lost for good as a result. Diskto-disk data protection combined with deduplication give
clear economic incentive to switch from tape to disk – from an acquisition cost and operational
expense perspective.
Data deduplication combined with disk-to-disk protection significantly increases the amount of
backups stored on disk, reducing the physical footprint of disk and the power and cooling costs
required to maintain the environment. In addition, having a larger number of backups on disk
greatly reduces the need to restore data from tape, saving IT departments a significant amount
of time managing, finding and loading tapes for simple restore requests. The DL2100 with
CommVault Simpana Data Protection oers a compelling disk-based data protection strategy
with built-in deduplication capabilities.
Save time and money with B2D combined with deduplication
• Reduced disk capacity for data protection
• Potentially fewer disk-to-disk backup storage systems over time
• Reduced power and cooling costs
• More available oor space
• More reliable data recoveries
• Faster data recoveries
• Less people-hours managing tape and disk administration
