Sounds good to me.  Yes, the data was coming from tape and since
mounting another volume took care of the problem and the backup was
successful after the Move&Rename volume was refreshed that way, I
wouldn't think it would be a server read error or corrupted data.
I doubt the backup would have continued so easily after just having
the folder refreshed if it was corrupted data.

Surprised me, all I knew about the Move&Rename folder before I got called
was internal Mac thing, ignore it. :)  Only thing I could think of was
that it had been written by a different system than the one the machine
was currently running (ie the floppy system not the one removed from the
hard drive) so create one from the current running system.  Hey, weak
I admit but, it solved the problem.

As always, good information and I appreciate the response.  Thanks.
