The Vault Capacity Has Been Used Up

Backup stops once the usage of the vault exceeds the upper limit. Take the following measures when the storage capacity of your vault is not enough:

• Log in to the CBR console, locate the target vault, and delete unwanted backups by following instructions in "Deleting a Backup".
• If you want to retain the generated backups, expand the vault capacity..
• If a backup policy has been applied to the vault, disable the backup policy or remove the policy from the vault.. Then, automatic backup is disabled, and the storage capacity of the vault will not change. You can also modify the backup policy or dissociate resources from the vault.

Other Operations Are Being Performed on the Resource to Be Backed Up

Automatic backup may fail when other operations, such as backup and restoration, are being performed on the target resource.

1. Log in to the CBR console and check whether the status of the target resource is Available or Running.

2. If yes, perform the backup again. If no, wait until the status of the target resource becomes Available or Running.
