Once we get reverse-journaling (UNDO records) working, we can do it the other way.. the mirror would contain the completely up to date filesystem and the journal files would be used to 'revert' it to an earlier state if necessary. This is safer because you can run the filesystem closer to 100% full (when it fills up you just remove the oldest journaling file), and you can restore a backup from the live mirror without having to run through any journaling files.
excellent work! great stuff!
