Limitations

CommunityEnterprise

• Only full level backups are possible. This is a Kubernetes limitation.

• The standard backup is not compatible with PVC with block volume.

• You can restore etcd only by using a local restore.

• The restart command has limitations with plugins, as it initiates the Job from scratch rather than continuing it. Bacula determines whether a Job is restarted or continued, but using the restart command will result in a new Job.

• PersistentVolumeClaims intended to be backed up via snapshot mode must belong to a StorageClass that uses the same type of filesystem format. It is worth noting that the default filesystem in Kubernetes is ‘ext4’.

• Static PersistentVolumeClaims can only use the standard backup mode.

• The plugin uses certain prefixes in the name of the PersistentVolumeClaims(PVCs) to identify the PVCs it has created itself. It is recommended not to use any of these prefixes to avoid issues. The prefixes are:

  • bacula-pvcfs

  • bacula-pvcclone
