When restoring from a CIFS/NFS backup, you must restore to the original NAS device. When restoring from a CIFS/NFS backup, the original location of the backup is the default restore target. If you wish to restore to a location on the NAS other than the original path, you must specify the full path to the restore target location.
For example, if the original NAS backup was of this directory:
/mnt/NAS/folder/subFolder1
and you wish to restore to:
/mnt/NAS/folder/subFolder2
enter the full path in the Target Directory field under Restore Advanced Execution Options:
/mnt/NAS/folder/subFolder2
Note: If you enter /subFolder2 only, the restore is written to the root mount point on the backup appliance (/mnt in our example). This could fill the root mount point and crash the appliance.
