Smart media copying using VLS

What is smart media copying?

In smart media copying, the data is first backed up to a virtual tape library (VTL)

configured on the Virtual Library System (VLS). Then, a copy of a virtual tape

containing a backup is made to the physical library attached to the VLS in a process

called automigration. Data Protector initiates the copy process, which is then

performed by the VLS. The data is transferred to a physical library in a smart copy

operation, which allows Data Protector to distinguish between the source and the

target media thus enabling media management. The smart copy media follow the

Data Protector format and can thus be inserted in any compatible tape drive and

read by Data Protector. The result of smart copying is two identical sets of media,

the source medium located on the VLS' virtual tape and the target medium (a smart

copy) located on a physical tape library attached to the VLS. Either of these copies

can be used for restore, thus increasing the security and availability of the backed

up data. You can also keep smart media copies for archiving or vaulting purposes.

Data Protector offers two types of smart media copying: automated smart media

copying and interactive smart media copying.

Automated smart media copying

You can create automated smart media copying of the following types:

• Post-backup smart media copying, which takes place after the completion of a

backup session and copies the media used in that particular session.

• Scheduled smart media copying, which takes place at a specific time or at regular

intervals.

Interactive smart media copying

Interactive smart media copying creates a copy of a medium containing the backed

up data and can be started on demand at any point in time.

What happens after the backup?

After the backup data has been moved to a physical tape, it is still available for the

Data Protector restore. However, since the destination library is not visible to Data

Protector, the restore cannot be performed directly from this library but from any tape

drive or library that is controlled by Data Protector.

For more information about VLS smart copies, see the online Help index: "smart

media copying" and the VLS documentation.
