Volume 'volname' cannot be backed up because 'nosnapdir=on' is set on the filer.
This message is issued when option 'nosnapdir=on' is in set for the volume indicated in the message. When this option is set, the volume snapshots are hidden and thus cannot be backed up.
The volume indicated in the message is not backed up. Processing continues with the next volume.
To back up the volume, change the volume on the filer: Set option 'nosnapdir=off'. Then try the backup operation for this volume again. If the volume is not backed up, remove it from the backup-archive client DOMAIN setting.
