svnadmin dump /path/to/repo > reponame.dump
tar zcf reponame.tgz reponame.dump
scp reponame.tgz hostname:/path/to/new/repo

Restoring a Repository

cd /path/to/new
svnadmin create reponame
tar zxf reponame.tgz
svnadmin load reponame < reponame.dump

Remove .svn directories

Because you forgot to do a svn export and lost the original source!

find | grep '\.svn' | xargs rm -rf
