You can delete unwanted backups to reduce space usage and costs.
If a backup has been used to create an image, the backup cannot be deleted. In this case, delete the image first by following the instructions in Deleting Images.
CBR supports manual deletion of backups and automatic deletion of expired backups. The latter is executed based on the backup retention rule in the backup policy. For details, see Creating a Backup Policy.
Note
- Backups are not stored on a server. Deleting backups has no impact on the server performance.
- If a backup already exists while the next incremental backup task is in progress, any attempt to delete the existing backup will be blocked. You must wait until the incremental backup finishes before performing the deletion.
- CBR automatically creates snapshots during backup and retains the latest snapshot for each disk. If a disk already has a backup, after another backup, the old snapshot will be deleted and the latest one will be retained.

- When you use CBR to back up a disk, all disk data including any invisible data will be backed up. If you frequently add, delete, or modify data on the disk before each backup task, a large amount of vault space will still be occupied even after some backups are deleted. You can reduce the occupied vault space by deleting unnecessary backups. For details, see How Do I Reduce the Vault Space Occupied by Backups?
