To delete backups from a device

When you delete a backup, it is logically deleted and you can no longer access it. However, the amount of available storage will not immediately increase and might not increase at all. The backup’s physical blocks are removed when the system performs a periodic purge. For deduplicated systems, a given block might be referenced by several backups, and unless all of these backups are deleted, the block is not purged, and your available storage space does not increase.

Caution: This procedure permanently deletes backups from the system. Once you click Confirm, you cannot stop the process. Any selected backups and dependent backups are deleted from the system. For example, deleting a full backup deletes any associated incremental and differential backups in that group. If any backups that are set to legal hold are selected for deletion, a warning displays asking if you really want to delete those backups. An entry in the audit log is created any time a backup that was set to legal hold is deleted.
