Delete backup copies

In addition to deleting backups after the retention period expires, 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 retention locking is not enabled, you can delete the backup copy prior to its expiration date. If retention locking is enabled, you must first override the retention lock of the backup copy from the Edit Retention wizard of the Infrastructure > Assets window.

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 differential backup copy, only the differential backup copy is deleted because there are no other dependent backup copies. 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, the full and differential backup copies are automatically excluded from deletion.

Regarding expired copy deletion for a backup chain, the full backup expires last. The differential and log backups that expire earlier than the full backup can be deleted when their retention time expires:

  • The full backup expires only when every other backup in the chain has expired.
  • A differential backup expires when its retention time expires.
  • A log backup expires only when all the log backups that depend on it have expired.

Steps

  1. From the PowerProtect Data Manager UI, select Infrastructure > Assets.
  2. 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.
  3. Select a protected asset from the table, and then click View Copies. The Copy Locations pane identifies where the backups are stored.
  4. Click Backup copies icon next to the asset type icon. The table in the right pane lists the backup copies.
  5. 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.
  6. 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.
  7. 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 that 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 are 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 are shown in the time zone used by the web browser. Go to Alerts > Audit Logs to view the audit log.

  8. Verify that the copies are deleted successfully from protection storage. If the deletion is successful, the deleted copies no longer appear in the table.
