A backup job for an Oracle Linux Virtualization Manager and Red Hat Virtualization VM could not enable incremental backup support. One of the following warnings may occur:
Unable to enable ovirt incremental backups for disk '':. Full scan backups will be performed. Please see KBxxxxx for more information
Unable to create incremental backup: Cannot backup VM. Incremental backup is not supported.
Unable to backup disks incrementally, using full scan backup.
This error specifically occurs when the disk is raw.
Here are the two most common causes of this issue and how to resolve them.
Incremental backup support may be disabled at the system level.
engine-config -s "IsIncrementalBackupSupported=true"
systemctl restart ovirt-engine
Copy
When creating a VM disk, if the option for ‘Enable Incremental Backup’ is not enabled, the disk will be created in RAW format and won’t support incremental backups. After the disk has been created, the ‘Enable Incremental Backup’ option will be greyed out and cannot be enabled.
There are two methods to resolve this limitation.
Note: The snapshot must remain in place. If it is removed, the Incremental Backup option will become disabled. In the long term, you should rebuild the VM/disk to have Incremental Backup enabled on the disk at the time of creation.
