Because it's one-way, so no worries about conflicts. I know I'm not
supposed to change the destination files but I like to use a one-way
backup solution.

I made two mistakes in my description.
First the tool is call rdiff-backup (and not rsync-backup which also
exists) : http://rdiff-backup.stanford.edu/index.html
Secondly, for the OS, I also use rdiff-backup and not rsync so I have a
fast, space efficient, incremental backup of the OS too !
PS: On the same web page you will also find a link to another tool call
duplicity (http://rdiff-backup.stanford.edu/duplicity.html). You can do
remote backup but in that case the image can be stored on a remote FTP
server and encrypted with GPG... sweet if you're planning to use the
disk space of your ISP for backups!
