Is there a really good reason not to tar the backups? It seems
impossible to have 50 million tarballs/days of backups, so I infer

homebrew a more intelligent backup system. Or just make the
journalling layer useful for backups.
matt hardlinks files which didn't change since the last N-level run.  this way there is always a full directory structure available.  it's fairly straight forward *and* intelligent, just our FS isn't too happy about that.
