What I do is keep a directory with running copies of every commit,
updated during the post-commit hook. This can be anywhere of course,
not related at all to where the actual repository is kept. Just add
a line like:
  svnadmin dump "$REPOS" --revision "$REV" --incremental --deltas >/var/svn/dumps/change.$REV 2>/dev/null
where '/var/svn/dumps' is the name of the backup directory. You could start out
by writing a little script to generate all of the changes to date, or just
with a full dump. Then to restore your repository is as simple as creating
a new one, loading in the "full" dump and all of the changes in order.

n.b. svnadmin dump does not dump the support files like the hooks directory,
so you may also want to keep a copy of those for easy restoration.
