In the networker client.

Yes.

Here's the thing...  When you ask it to back up /vol/vol1, you're not
really backing up the live volume.  Instead, it makes a snapshot, and
it backs up that snapshot, then deletes the snapshot when complete.
You can see this in 'snap list' during the backup.  So it doesn't
descend to the other ones.

The Netapp snapshots are just different views to the data.  I imagine
that if you have 30 snapshots of a 2TB volume, that most customers
don't want a backup of the filesystem to require 60TB to capture all
the views.

No.  You're backing up one particular snapshot (even though it's named
/vol/vol1 to the backup server).  You can't view other snapshots from
within that view.  (If you cd into a particular snapshot, there's no
longer a .snapshot directory inside that view.)

Netapp dump (which is what NDMP uses) doesn't have any facility for
dumping multiple snapshots at a single time.
