Backuppc (http://backuppc.sourceforge.net/) would do this for you without writing any code and using less space than a single full backup, and give you a web interface to grab or restore files to boot. Actually the space required will depend on how compressible the files are and how many duplicates you have, but it is pretty impressive. And it can use tar or samba as the transfer method as well as rsync. -- Les Mikesell lesmikesell@xxxxxxxxx
