Considerations For Copying To Physical Tape Through The Backup Application; Copy To Tape Using Vls Automigration - HP StorageWorks 12000 - Virtual Library System EVA Gateway Manual

• Use the functionality of a backup application.
• Copy only the specific files you need onto physical tape.
• Not waste tape storage as physical tapes can be fully filled.
• Monitor and track copy jobs from the backup application.
• Use any tape library that is supported by the backup application.

Considerations for Copying to Physical Tape through the Backup Application

There are potential drawbacks to using a backup application instead of caching to copy data on the
VLS or D2D to physical tape. Consider the following when deciding which data migration method to
use:
• You must purchase additional backup application licenses for the physical library.
• You must configure a backup application with a scheduled copy job to perform the migration.
• If you have the media servers on different SAN switches from the libraries, copy bandwidth is
added to the SAN during data migration.

Copy to Tape using VLS Automigration

You can migrate data from virtual media in the VLS device to physical tape media using
automigration/tape-offload to perform transparent tape migration. The automigration echo copy
feature allows the VLS to act as a tape copy engine that transfers data from virtual cartridges on disk
to a physical tape library connected to the VLS device. See
Echo copy essentially acts as a transparent disk cache to the physical library so echo copy jobs can
be performed at times other than the peak backup window. Once automigration is set up, echo copy
operations are automatic and seamless to the user. Echo copy is managed through the automigration
software on the VLS instead of through the backup application.
