This doesn't help you when your storage is all on NetApps, then you
need to goto NDMP at some point, though we're still NFS based due to
our concerns with restore limitations. We have LOTS of files and lots
of data and the old NDMP limitation of 10,240 file restores from DAR
backups was a killer.
I know the limit is now upto 1,000,000 files, but we're still worried,
since our users expect to be able to restore arbitrary amounts of data
at any time, and some areas have alot of files. So we'd hate to have
to break it up.
We should just jump into the water I guess...

We're looking at how to connect our NetApps to Networker to Disk to
Tape. Fibre Channel seems to be the right move, but we're not sure.
We do want to stage to disk first, then to tape, but that brings in a
whole lot of cost for disk which sits around alot, which the bean
counters don't like to see. :]
