I tried backing up to a file instead of the tape drive in order to see if
I could narrow down where the problem is located. It completed the full
backup of 27GB in 1618 seconds (27 minutes). I used xfsdump to do it. This
would indicate to me that there isn't anything wrong with the file system or
any problems with large sparse files as others suggested I check. Since that
worked with out problems, it would seem to me that the real problem is with
the tape drive connection. I've already tried a couple of different tapes
with out any luck. Could it be the drive itself? Anyone have any other ideas
for me to check out? Thanks.
