Enabling Enterprise Integration and Migration
Enterprise integration enables a backup management application (BMA) server to read and
write files to and from Virtual TapeServer (VTS). You can enable VTS to migrate virtual tapes
to physical tapes. To configure VTS to automatically migrate virtual tapes, you must install a
BMA client on the VTS server and configure the VTSPolicy command in conjunction with the
Event Management Service (EMS) on VTS. You can also manually initiate migration by
clicking the Migrate button on the Virtual Media - Operation page. A BMA client must be
installed on the VTS server to enable manual migration.
VTS supports the following BMAs for migration:
• IBM Tivoli Storage Manager
• Symantec Veritas NetBackup
• Syncsort Backup Express
• EMC Legato Networker
Migration allows for better use of the disk space on the storage array. For instance, if a virtual
tape needs to be saved for seven years for legal purposes, it is not fiscally prudent to keep that
data on disk. You could automatically migrate the virtual tape to physical tape. In the
unlikely event that the virtual tape is needed, VTS can automatically request that the BMA
server restore it from physical tape.
When a virtual tape is migrated to physical tape, all data on the virtual tape is written to
physical tape, including the header information (metadata). The data is then removed from
VTS, though the virtual tape’s metadata is retained. To restore a physical tape that was
automatically migrated by a BMA, the BMA must restore the tape to VTS. Host servers
cannot read physical tapes that were created through migration because the tape is formatted
for use by VTS only. After the data is restored as a virtual tape in VTS, the host server can
then restore the data.
Note You can export a virtual tape to physical tape, which does not require BMA
integration. See the Virtual TapeServer Operations and Administration Guide for
more information about exporting virtual tapes.
