NDMP backup fails with "Backup of non-local Volume...not supported"

Applies to

• Clustered Data ONTAP 8.2 - 9.x
• NDMP Node-Scope mode is enabled

Issue

• When attempting to perform a backup, the job fails before any data is transferred, reporting:

Operation terminated: Backup of non-local Volume '/vserver name/volume name/path' not supported (for /vserver name/volume name/path)

• The backup that is now failing may have worked in the past.
• Clients are still able to access the data via NAS protocols (NFS,CIFS,) but backup via NDMP protocol fails.
