One of the things that I sometimes have to do is move an SVN repo to another server or you just want to back it up. This tutorial will show you how to do this.
svnadmin dump /pathToYourRepo > reponame_dump Example: svnadmin dump /var/svn/mywebsite > mywebsite_dump
So now you want to go move this file to your new server and create your subversion repo. Make sure you use the same name as the old one. Go to folder where you uploaded your dump file to and do the following:
svnadmin load /pathToYourRepo < reponame_dump Example: svnadmin dump /var/svn/mywebsite < mywebsite_dump
So there you go. In this tutorial I did not include setting up the subversion server cause I made the assumption you know how to do this since you already have an SVN repo setup.
