It's an interesting question... our repository is on a partition which
contains a bunch of other stuff, and the entire partition gets backed up
regularly. But for really big repositories, it would probably be easier
to do incremental saves (you get the last backed-up revision, and dump
from that to HEAD only). I don't know if that's possible though, or
easily accomplished.

There are of course other ways to obtain the same result - by backing up
all of the berkley DB transaction logs before deleting them, you can (in
principle) rebuild an entire Berkley database without even having
subversion on there by replaying all the transactions. This also gives a
way to do an incremental back-up - you are only backing up the most
recent DB log files.

As suggested, you can dump & load the repository, or simply copy the
repository data (if you have your repository in /opt/svn then tar cfj
svn_backup.tar.bz2 /opt/svn will work). It's usually a good idea to
clean out your database logs regularly if you're diong this, since
otherwise you're basically doubling up the information you need.

Cheers,
Dave.
