I'm starting to dig though and look. An initial hunch is access dbs. I
know there are several living on this server, and many are for daily
use. If they grow much, that would account for a hunk. I've also done
a spot check that shows about what you would expect with changes on word
docs, etc. So, I'm leaning to a combination of largish access dbs and a
standard amount of other stuff.
I'm searching through the last backup now for a count and size of mdbs
to see if I can support my hunch.
Thanks all for your suggestions,
Jason
