Insufficient. You also need the Apache or svnserve or SSH configs, and
the varoius commit scripts from the base repository, along with their
ownership and permissions. Tarballs are good, "rsync -avH" is even
better for imaging such loactions in a decodable format.

svnadmin does not do full backups. It does *database* backups, but
does not mirror the rest of the configuration.

See above.
