Hi,

If you specify a save set like /vol/root, the Volume will be backed up
without the .snapshot Folder.
Even if you specify somthing liket this, /vol/root/.snapshot you'll run
into an error.
The snaps are "frozen views" of the active filesystem at a specific
time.
If you want backup a snapshot you have to configure the snapshot
explicitly as a save set: /vol/root/.snapshot/snap_to_tape
This will back up the snapshot, but be careful, if you backup a snapshot
like this, you will always do a full backup.
The NetApp snapshot technology will of course not transferred to tape,
this means you are not able to backup just the deltas, you see in the
snapshot on the volume. It's like a backup of the whole volume, at the
time the snapshot has been created.

Cheers

I am testing backing up our Netapp 2050 filer and was wondering how or
if I can recover the snapshot folder for each volume. I do not see it in
the Networker User so I wonder if they are not a part of the backup,
they are hidden and therefore I cannot see them, or do I need an enabler
to back them up. I am currently using NDMP backup to a non-NDMP device
connected via SCSI to my Networker server which is running 7.4sp1

Thanks
