Basesnapshotname
The basesnapshotname option specifies the snapshot to use as the base snapshot, when you perform a snapshot differential (snapdiff) backup of a NetApp filer volume. If you specify this option, you must also use the snapdiff option or an error occurs. If basesnapshotname is not specified, the useexistingbase option selects the most recent snapshot on the filer volume as the base snapshot.
If the specified snapshot cannot be found, an error is reported and the backup operation fails.
