Integration with Physical Tape
In most backup environments, physical tape is still used for long-term storage and offsite archiving. Backup to
disk users need to export backups to physical tapes for archiving with the knowledge that they will be able to
recover that data if necessary. With that need in mind, the Dell PowerVault DL2000 powered by CommVault is
available integrated with a Dell PowerVault TL2000, TL4000, or ML6000 tape library.
The PowerVault DL2000 manages tape as an integral part of the backup infrastructure. Physical tapes created
by the PowerVault DL2000 are managed natively by CommVault software. This allows administrators to restore
tapes without conversion. It also means that in a disaster situation, the tapes can be restored directly by the
backup application in an alternate location.

ESG Lab Testing
ESG Lab first looked at tape creation procedures. Figure 14 shows an example of disk to tape configuration in
operation. First, a retention policy was created to automatically move backups from disk to tape after 15 days
and then a policy was created to make second tape copy after 2 days for offsite use.
