FIGURE 14. DATA RETENTION POLICIES
ESG Lab next used the Auxiliary Copy function to manually create a tape copy of an existing disk backup of a
Microsoft file server. Once the copy was complete, the backup set was browsed from the tape and individual
files were selected and restored to an alternate location. ESG Lab then verified the validity of the files by
performing a ‗compare‘ and determined that the restored files were identical to the original source files.

Why This Matters
ESG research shows that 87% of organizations integrating disk-based systems into their backup strategy
still incorporate physical tape in their backup policies.

Tape copies are made for offsite DR, archival, and
compliance requirements. A disk-based backup solution ‘s integration with physical tape enables IT
managers to meet these requirements as they move an increasing amount of operational backup and
restore operations onto disk-based systems.
ESG Lab validated that the Dell PowerVault DL2000 Powered by CommVault integrates tape seamlessly
using Simpana‘s built-in media management functions. ESG Lab controlled the process using the Simpana
GUI, which provided fully independent control of disk and tape tiers. This allowed different expiration policies
for the same data in different locations, all under the same single point of management. These capabilities
provide offsite and archive capability to small and medium-size enterprises at low cost and minimal
management overhead.
