Deleting a Backup

You can delete unwanted backups to reduce space usage and costs.

Deleting a backup from a hybrid cloud backup vault does not affect the corresponding backup on-premises, and vice versa.

If a backup has been used to create an image, the backup cannot be deleted. For details, see 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.

Backups are not stored on a server. Deleting backups has no impact on the server performance.
If a backup has been created and the next backup task is in progress, CBR will not allow you to delete the most recent backup created. You can delete the backup only after the backup task is complete.
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.

Prerequisites

There is at least one backup.
The backups to be deleted are in the Available or Error state.

Billing

You are billed for the storage space and the data traffic generated if backup replication is used. Pricing of the storage space varies with vault types. The vault capacity remains unchanged after backups are deleted, so the charges remain unchanged.
For details about billed items, see CBR Billing. For details about pricing, see CBR pricing details.

Procedure

Log in to the CBR console.
1. Log in to the management console.
2. Click in the upper left corner and select a region.
3. Click and choose Storage > Cloud Backup and Recovery. Select the corresponding backup type from the navigation pane.
Click the Backups tab and locate the desired backup. For details, see Viewing a Backup.
Choose More > Delete from the Operation column. Alternatively, select the backups you want to delete in a batch and click Delete in the upper left corner to delete them.

Click OK. Return to the backup list. If the target backup does not exist, the backup is deleted successfully.

Documents

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 vault space occupied. For details, see How Do I Reduce the Vault Space Occupied by Backups?
If the Delete button is unavailable or the deletion fails, rectify the fault by referring to Failed to Delete a Backup.
