Burak,

You can automate the return of volumes using AutoVault. (See
www.coderelief.com and search the adsm.org archives for detailed
information regarding AutoVault's capabilities.)  In comparison to
AutoVault, DRM is missing some capabilities, such as automated vaulting of
backupsets and automated generation of tape rotation reports to email and
printer.

We have been using AutoVault extensively, and are very happy with what it
enables us to do.
