Backup Exec 20.2 Administrator's Guide

Allow Backup Exec to delete all expired backup sets

This global setting lets Backup Exec delete expired backup sets, even if they are the last remaining backup sets that you need to restore a server. Use this option when you want to delete backup data after a period of time. Alternatively, you can manually delete backup sets.

To access this option, click the Backup Exec button > Configuration and Settings > Backup Exec Settings > Storage.

See Editing global settings for storage.

Limit Backup Exec to read-only operations on a disk-based storage device if it has been detached for x number of days

This global setting prevents Backup Exec from deleting expired backup sets on any disk-based storage device as soon as you reattach it. When you limit Backup Exec to read-only operations, you have time to review any expired backup sets and determine if you want to keep them before data lifecycle management deletes them. To keep expired backup sets, you can retain them or change the expiration date.

See Retaining backup sets on disk-based storage to prevent them from expiring.

See Changing the expiration date of backup sets on disk-based storage.

Backup Exec is limited to read-only operations only on the disk-based storage devices that are detached from the Backup Exec server for the specified number of days.

To access this option, click the Backup Exec button > Configuration and Settings > Backup Exec Settings > Storage.

Limit Backup Exec to read-only operations on a disk cartridge if it has not been inserted for x number of days

This global setting prevents Backup Exec from deleting expired backup sets on any disk cartridge as soon as you insert it into a disk cartridge device. When you limit Backup Exec to read-only operations, you have time to review any expired backup sets and determine if you want to keep them before data lifecycle management deletes them. To keep expired backup sets, you can retain them or change the expiration date.

Backup Exec is limited to read-only operations only on the disk cartridges that are detached from the Backup Exec server for the specified number of days.

Limit Backup Exec to read-only operations

This device property prevents data lifecycle management from running on a specific disk-based or disk cartridge storage device that you reattach or reinsert it. This option applies only when the storage device has been absent from the Backup Exec server for the number of days that you specify in either of the two previous global settings described in this table.

To access this option, on the Storage tab, right-click the device, click Details, and then click Properties.

Low disk space

This device property is the first of three low disk space conditions. When the storage device's used capacity reaches this threshold, the data lifecycle management feature immediately searches the device for expired backup sets that it can delete.

Data lifecycle management also runs on a disk cartridge if the cartridge reaches capacity during a backup job. The backup may not need to span to another cartridge if data lifecycle management deletes enough expired backup sets. If a job does span and you insert a new disk cartridge that is full, data lifecycle management deletes expired backup sets on the new cartridge.

To access this option, on the Storage tab, right-click the device, click Details, and then click Properties.
