You don't have to write any Perl to talk to the server: Craig has done an outstanding job of packaging the functions of BackupPC into powerful command line functions. Virtually anything you can do from the GUI (and more!) can be done from the command line, using *any* language you want.

In addition, BackupPC stores everything you see in the GUI in nicely formatted text files that can be processed however you would like. The most important one being the "backups" file in each host's directory.

I'm glad that pointing that out helped!
