Nope, nothing that I can see.

Well, if I leave bbackupd service off, the problem goes away, so I think that
confirms the same thing.

It appears that (in this morning's case, at least) this was true. I got the
"Connection made, login successful" message at 8:54 and the user complained
about the lock at 8:59. I immediately shut down the service, the user logged in
ok, and I started the service again at 9:00. I'll keep an eye on it for the
next few days to see if this same timing continues.

Or maybe I'm just better off in snapshot mode. This one file is really the only
thing I need to backup on this server and it gets changed pretty much all day
long.
