The best approach is to be prepared and use a good backup strategy.

From the post-commit hook, create an incremental dump file of every revision.
You can do this with svnadmin dump --deltas --incremental -r $REV.
This gives you nearly instant backup of every commit that made it into
the repository. Incremental dump files can be large if a large tree is
added, but in general they don't use much space.

After restoring the last full backup of the repository, load missing
revisions from the incremental dump files generated since the last
full backup was made.

You can either get rid of incremental dump files dated before the
last full backup, or keep them around in case you'll need them some day.
Having multiple backups of your data in different representations
doesn't hurt.
