Remote access of subversion repositories
Using Remote Subversion Repositories With your offsite filesystem
You are able to run the 'svnserve' command, remotely, over SSH. This means that if you upload a repository to your offsite filesystem (using rsync or sftp, etc.) you can then access that repository using a:
style URL. You can use this URL in any application that supports them. The 'svn' command, as well as TortoiseSVN are good examples of tools that can operate on such URLs.
You do not have the ability to run the 'svnadmin' command remotely, so you should create your repositories locally and then upload them.
Be sure to include your username in the svn+ssh:// URL - the 'svn' command will not prompt you for it, although it will prompt you for a password.
