Do this in the 'post-commit' hook. That's what I do; I keep incremental
revision backups for every commit and then slosh them about using rsync.
The hook is told the name of the revision and the repository path, so
it can be pretty dumb (extract, like this):

  CHANGES=PATH_TO_CHANGES/change.$REV
  svnadmin dump "$REPOS" --revision "$REV" --incremental >${CHANGES} 2>/dev/null
