If you no longer need a backup unit and its backups, you can delete them to save costs and space. Deleting a Backup Unit also deletes all backups it contains.
— When you delete a server and its storage devices or an entire data center, its backups are not automatically deleted. Only when you delete a backup unit are the backups it contains deleted.
— If you no longer need the backups of deleted VMs and want to save costs, you must delete them manually in the Backup Management Console.
1. In the DCD, go to Menu > Storage >Backup Unit Management under Backup Service.
2. Select the required backup unit to be deleted.
3. Click Delete.
3. In the dialog, confirm the delete action by entering your Password and clicking OK.
Result: The selected backup unit and the backups it contains are successfully deleted. Once deleted, the backup unit cannot be restored.
