Mac OSX backup without time machine

After doing massive research to make OSX time machine to work with QNAP TS-109, the result fails. The making filesystem stuff doesn't work for me.

While searching for replacement proposals, I think rsync may be the answer. I tried to make rsync connection from Leopard to TS-109, it works! Now, I just make a simple backup with following command:

rsync -a --delete . nas_ip:/share/backup/mac

This will backup the current directory to "mac" folder in "backup" share. Of course, the job could be done by cron job. However, I'm using MacBook and travel with it a lot. I'll fire the backup command when I feel comfortable.
