backup02 itself is only doing 1 rsync at a time. ;)
I'm not sure what other virtual systems are being backed up that would
affect it. None of the other guests on ibiblio01 are backing up to
backup01. I guess they do run daily jobs at the same time, so that
could put stress on the host... but it's pretty weird.
I made the deadline change, we will see if that helps any.
