TortoiseSVN x RiouxSVN (repository back-up)

I'm starting to work with version control using TortoiseSVN, and RiouxSNV as repository. It turns out that sometimes I need to stay a few days without internet access, I would like to be able to export the entire repository to a local folder on my computer, to be able to work offline, and after a few days return the repository to the online server. How can I make this copy of the entire repository, not just a working copy. Oh, I have no problem when conflicting with other users, because when I go to do this no one else will be tinkering with the repository. So what I really need is to swap the repository from location to online, and vice versa, loading all the modification history.
