Not exactly, but if you want to continue with this course, I do have a
script which may serve as a starting point. This started life as a script to
write BackupPC archives to tape, and was thereafter modified to write the
archives to disk attached via USB, so it's a bit crufty. Also, I haven't
looked at it for many years and it hasn't been used for many years, but it
may give you some ideas on how to use if you want to start working.
I'm not even sure it works, for that matter. This is just what I found in my
development archives. It was too many years ago that I worked on this
problem, and the script is plainly in a development sort of phase. (Hence
the bash -x and the FIXME note).
