I know this is about Perl...but, why you don use tools like rsync (http://www.rsync.org) or apt-get.

Apt-get is wonderfull tool, there're also other tools like apt-get.

I use rsync for so many tasks, like file syncs, mirroring, etc

Another really interesting tool is Unison (http://www.cis.upenn.edu/~bcpierce/unison/), for syncronise host in a two directions way.

Hope it can be useful. Regards
