If you're backing up a NetApp filer via the CIFS share and are not
specifically excluding the snapshots, you ARE backing them up, as they
are simply a subdirectory under the share (~snapshot).  Are you sure
you're excluding them?

As to your statement that you "did not purchase the tools required to
backup the snapshots," I'm not sure what tools that would be referring
to.  Perhaps you don't have the right tool to automatically create a
snapshot at the time of backup (NDMP would do that for you), but all
snapshots are available via the CIFS share (which is what allows users
to access and restore from them so easily), so all you have to do is
specify the snapshot directory in your include spec.  (Instead of
specifying N:\share, you specify N:\share\~snapshot\daily.0, which IFIRC
should be the most recent snapshot.)

Thanks, I'll check into the virus scan and memory.  As for the
snapshots, no we are not backing them up.  I think we may look into that
in the future but I was told we did not purchase the tools required to
backup the snapshots.

Sounds to me like the TSM Client, a Windows 2003 server needs to have
more
memory.
Or it's virus scanning the file share as it's backing it up.

Also look into the 'snapshots' that NetApp may be doing on the file
shares.
Are you also backing up them in addition to the current data?

That could easily quadruple the amount of data backed up with TSM of a
NetApp share.

Having TSM only backup the 'nightly.0' 'snapshot' or some such could
work
too, I think, for a nice consistant TSM backup of a NetApp
