Automatic Subversion Backup

Having a backup system is important for your personal data, but nothing is more critical than backing up your code. If you are a heavy subversion user (like me) you need an automatic backup solution for your subversion repositories. Here’s a little Unix script to handle backing up your precious code.

svn-backup:

I set up a cron job to run this script every morning at 5am:

svn-backup /var/svn/ /var/backups/svn
