How To: Subversion Backup (niden.net)

Good discussion of the options.

I'm a big fan of the simplicity and usability of the hot-backup.py script that the subversion team provide

svnsync would synchronize the whole repository to the target location. That is OK if you want to keep a copy elsewhere. One of the solutions that I provided allows you to dump each version in turn which svnsync does not do.

Having written that, svnsync would definitely be another option to consider.

Thank you for the reminder!
