Shell is ubiquitous, you won't run into a (*nix) server without it.
Perl is nearly so, but ymmv. I've done it both ways and I think the
Perl ended up being more readable (ironic?) and more potentially
maintainable by someone else. As long as you clearly document the
process, I'd imagine anything you want would work. Realistically, you
can't get it wrong, so I'd say do what works best for you in your
particular situation. If you want to do it in PHP by all means go to
it, the biggest issue with that has already been mentioned. Shell is
the most portable and probably the most cryptic. Perl is a close
second in portability but reasonably less cryptic if done right. Using
anything else means you'll have another tool chain to install on any
new servers you bring up or any servers you want to migrate that
backup process to.
