Well, yes and no.  Remember that some platforms are still supported with
clients that are based on pre-V6 code.  It doesn't matter if you're using
a 7.1.3 or 7.2.1 server if your client software is still pre-V6.  That
was the case for NetWare until just a few weeks ago, when a true V7 client
was released for that platform.  There may be other platforms that have
the same limitations.

You're right, though, that whether savesets can be larger than 2 GB (or
whether they're "chunked" into continuation savesets, as was done with
pre-V6 clients) or not has nothing to do with Teresa's question.

I don't have any experience yet with advanced file type devices, but I
would be pretty shocked if NetWorker on Solaris 9 (whether or not its
the 64 bit server) couldn't use adv_file devices in the TB size range.

Interestingly enough, when writing to tape, NetWorker never makes a single
file *on tape* larger than 2 GB.  If you have a saveset that consists of
one file that's 5 GB in size, when NetWorker writes it to tape it will
have one saveset id but (at least) three file numbers (mediafile, in
mminfo parlance) on tape.  I don't know if it does the same thing when
writing to an adv_file devices.  I wouldn't be surprised if it did.

Hopefully I'm not making the situation worse.  :-)
