Patches should be applied to production systems during a service window.
A backup of the File Fabric appliance should be made during the service window and prior to applying the patch.
If the database is external to the appliance then the database should also be backed up.
A confidence test of the patched system should be conducted within the service window.
If the confidence test exposes an issue and a rollback is required, the appliance backup should be restored.
If the database is external, the database backup should be restored.
