I want to use SVN to make a backup of my system, using Raspberry pi.

There is a NAS, where some users make changes in a folder, and do a 'backup' to SVN repo. I have SVN repo set up, and already checked out the files, but if I make changes over samba, the commit will not affect the repo. I want to make automatic copy(commit) of them. I want to have an automatic backup of the files, maybe with crontab which run every 1 hour, or so. 

There is no option to commit every files with a single name, I want to make it automatically. 

If there will be an automatic backup with tar.gz, send it over maybe FTP, the files size will be much more, than the regular SVN, and there will be no version control.

I tried <http://gael-varoquaux.info/computers/svnautocommit/>, but it has a lot of bug.
