I use LuckyBackup, its a GUI front end for rsync. Its pretty fast at copying over files that have been changed and has an optional feature to delete those that you've got rid of.
Although I don't think it has a way of continually monitoring for changes. I only use it for doing an occasional backup of my entire home folder to an external USB harddrive. Ivan -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
