rsync is nice in that it only copies modifications made to a repository
across. But the problem is you have to guarantee that the repository is
in a consistent state. Someone writing to the repository as you're
running rsync could mess up the backup.

svnadmin hotcopy would be very slow with a repo of the above size. But if
there was a way to 'lock' the repository from being written to for a time
being without shutting down (apache web service / svnserve / file system
access) for the purposes of backing up the repository with you're tool of
choice (ie. rsync), that would be awesome.

Is there such a way?
