Issues mirroring and SVN repository

I am trying to mirror a repository to my local machine. From what I have read the best way to approach this is using svnsync. When I go to set up this i am getting errors back that svnadmin and svnsync are unknown commands. Is there an add on I开发者_开发知识库 need to download to be able to perform these commands? The basic command line commands for svn are working fine such as checkout, update, etc

What is the version of your svn? With the new version of subversion 1.4 you have a new tool called svnsync with which you can maintain mirror repositories quite easily.
