Not that I'm aware of.  There appear to be two ways this could occur.
The NDMP host could dump all of them, or NBU could find them back them
up separately.

I don't see any way for the first to happen.  'dump' seems to work on
only one filesystem, and each of the snapshots act like independent
filesystems.  So you can't get it in a single restorable bunch.

The second also seems to not work.  I don't know any way to get NBU to
query the NDMP host and back up everything.

Nope.  Again, independent filesystems.  Because the NDMP server is just
passing this on to the Netapp dump, you can try this...

netapp> dump 0f null /vol/yourvol/.snapshot/*snap_lun0*

filer> dump 0f null /vol/vol0/.snapshot/*hourly*
DUMP: cannot open /vol/vol0/.snapshot/*hourly*. 
DUMP: Dump failed to initialize.
DUMP: DUMP IS ABORTED

That could match multiple filesystems, and dump can't handle multiple
filesystems.

Query the netapp for the list of snapshots.  Then put any matching
snapshots into your policy.

ssh <filer> snap list <volume> (or use snmpwalk on slVEntries)
bpplinclude <policy> [ -add | -delete | -modify ] <path...>
