Tried a few for this and besides the unmaintained part, they dont stand up to the battering that rsync dishes out - regular corruption. If you have space, look at dirvish (its in portage) on reiserfs. Tried it on ext2 and ext3 - more corruption but reiserfs3 with data=journal is rock solid. The devs reccomend not using a journaled FS for performance, but I found it essential for my setup. Dirvish takes the full size for the first backup. Subsequent backups create hard links to existing files so only differences show up as using space. After a number of backups, total size stabilises around 2x original space unless you add some large files, or do an "emerge -ep world" :) Can be easily managed by cron and ssh keys including how many backups to keep etc. Can use on a local system, or more usually to a remote machine. Restore is as simple as copying the files back (though special files an permissions need to be maintained so a simple copy isnt viable for a full system restore.) BillK
