Managing Media

Using a Pre-Allocation List of Media for Backup

Using a Pre-Allocation List of Media for

Backup

You can specify the order in which media from a media pool will be used for backup. This order is called a pre-allocation list. You specify the pre-allocation list when configuring a backup. The purpose of a pre-allocation list is to control which media will be used for a backup session. You have to match the pre-allocation list with the available media before each backup.

Depending on the allocation policy of the media pool, Data Protector behaves in two different ways:

If the pre-allocation list is used in combination with the Strict media allocation policy, Data Protector expects the media in a backup device to be available in that order. If the media are not available, Data Protector issues a mount request. If the media mentioned in the pre-allocation list are loaded in a SCSI-II exchanger, Data Protector handles the media sequence automatically.

If the pre-allocation list is used in combination with the Loose media allocation policy, media in the pre-allocation list are used first. If the media are not available, any suitable media in the library are used.
