The backup and restore model for Unified Manager when installed on a virtual appliance is to capture and restore an image of the full virtual application.
If the datastore is not hosted on a system running ONTAP software, follow the storage vendor guidelines to create a backup of the VMware snapshot.
You should implement a backup schedule using these tasks to ensure that the Unified Manager virtual appliance is protected if issues arise.
To restore the VM, you can use the VMware snapshot you created to restore the VM to the backup point-in-time state.
