If you are very low on space you can do this every time you finish copying a new volume to the NERC. If on the other hand you have plety of remaining space feel free to leave all of your Volume Backups as they are.

    $ openstack --os-cloud moc volume backup list
+---------------------+------+-------------+-----------+------+
| ID                  | Name | Description | Status    | Size |
+---------------------+------+-------------+-----------+------+
| <MOCVolumeBackupID> | None | None        | available |   10 |
