[CentOS] Automatically check into SVN?

I would like to automatically check in a directory to SVN, to maintain 
the changes that area made to those txt files over time. These files are 
configuration files, and it would be good to be able to revert back by 
simply checking out the older versions. But I would to check in the 
files every files minutes, and I'm sure SVN will not use up any disc 
space, unless there are any changes.

I already have an svn server up and running in production -- Any help?
