I confess my first reaction is that any time your answer involves two
different backup systems working in series, you probably asked the wrong
question in the first place. If you're just copying all this data to
tape for an offsite archive copy (which, one presumes, you're going to
date and periodically rotate), why don't you just dump it with, say,
cpio/afio?
