Having the same problem as Kurt, I'd like to second his request for a
seed file. The dump seems the more sensible approach, although the tar
will work as well under most circumstances.

Some insight on how FreeBSD does it, can be found here:


Such a seed would have to be updated every now an then, but not too often.

rsync would be another alternative, which I have been using to clone
some repos from SF.net for some time now. They offer this option for
backup purposes.

Indeed, it does.

The git mirrors only contain what's in trunk in the SVN repos.
