In addition to deleting backups upon expiration of the retention period,
PowerProtect Data Manager enables you to manually delete backup copies from
protection storage.
About this task
If you no longer require a backup copy and the retention lock is not enabled, you can delete backup copies prior to their expiration date.
Starting with
PowerProtect Data Manager version 19.6, you can perform a backup copy deletion that deletes only a specified part of a backup copy chain, without impacting the ability to restore other backup copies in the chain. When you select a specific backup copy for deletion, only that backup copy and the backup copies that depend on the selected backup copy are deleted:
When you select to delete a full backup copy, any other backup copies in the chain that depend on the full backup copy are also deleted.
When you select to delete a cumulative backup copy, any differential backup copies that depend on the selected cumulative backup copy are also deleted. The whole backup chain is not deleted.
When you select to delete a differential backup copy, any other differential backup copies that depend on the selected differential backup copy are also deleted. The whole backup chain is not deleted.
When you select to delete a log backup copy, any other log backup copies that depend on the selected log backup copy are also deleted. The whole backup chain is not deleted.
When you select to delete all log backup copies without selecting any full, cumulative, or differential backup copies, the log backup copies that the full, cumulative, and differential backup copies depend on are automatically excluded from deletion.
Regarding expired copy deletion for a backup chain, the full backup and its dependent log backups expire last. The other cumulative, differential, and non-dependent log backups can be expired and deleted earlier:
The full backup expires only when every other backup in the chain has expired.
A cumulative backup expires only when all the differential backups that depend on it have expired.
A differential backup expires when its retention time expires.
A non-dependent log backup expires only when all the log backups that depend on it have expired.
A dependent log backup expires only when all the full, cumulative, differential, and log backups that depend on it have expired.
Steps
From the
PowerProtect Data Manager UI, select
Infrastructure > Assets.
From the
Assets window, select the tab for the asset type for which you want to delete copies. If a policy has been assigned, the table lists the assets that have been discovered, along with the associated protection policy.
Select a protected asset from the table, and then click
View Copies. The
Copy Locations pane identifies where the backups are stored.
In the left pane, click the storage icon to the right of the icon for the asset, for example,
DD. The table in the right pane lists the backup copies.
Select one or more copies from the table that you want to delete from the DD system, and then click
Delete.
A preview window opens and displays the selected backup copies and all the backup copies that depend on the selected backup copies.
NOTE If you delete a backup copy,
PowerProtect Data Manager deletes the specified backup copy and all backup copies that depend on the specified backup copy.
For all asset types, you can choose to keep the latest backup copies or delete them. By default,
PowerProtect Data Manager keeps the latest backup copies. To delete the latest backup copies, clear the check box next to
Include latest copies.
To delete the backup copies, in the preview window, click
Delete.
NOTE The delete operation may take a few minutes and cannot be undone.
An informational dialog box opens to confirm the copies are being deleted. To monitor the progress of the operation, click
Go to Jobs. To view the list of backup copies and their status, click
OK.
When the job completes, the task summary provides details of each deleted backup copy, including the time that each copy was created, the backup level, and the retention time. The time of copy creation and the retention time is shown in UTC.
An audit log is also generated and provides details of each deleted backup copy, including the time that each copy was created, the backup level, and the retention time. The time of copy creation and the retention time is shown in UTC. Go to
Alerts > Audit Logs to view the audit log.
Verify that the copies are deleted successfully from
protection storage. If the deletion is successful, the deleted copies no longer appear in the table.
