I doubt that anyone here is going to be able to give you any help on
something as old as RH7.1. Even people who run OSes for years switched to
some version of RHEL years ago so the chances that someone reading this
group still has a running RH7.1 system is remote.

I think that you are making your life hard by trying to get a new piece of
equipment to work on that system, if it worked right out of the box then
it would have been fine but since it didn't I'd forget about it. There are
a lot of ways that you can accomplish your backup task. The simplest is to
just use rsync to copy your files from the old system to a new system.
