Root folder creation date

Some comments on SuperDuper's impact on root folder creation dates, and the consequences to running DiskWarrior. I saw some older messages in the forum, but they were running in Erase mode, not Smart Update...


I'm running SuperDuper! in Smart Update mode to an external drive that also contains a Time Machine database.

A few days ago I ran DiskWarrior 4.1.1 against that drive. The result was it needed to repair the creation date on 958,390 hard link files! I believe that represents every single hard link on the drive.

Alsoft says it did this because it had to repair the root folder creation date. Repairing this date then caused it to need to repair all the hard link directory entries -- the hard link catalog entry's creation date should be the same as the root folder, or the HFS+ private data folder.

It got this way because every time I run SuperDuper (even with Smart Update), it changes the backup drive's root folder creation date to match the source drive. The result is that the root folder creation date is less than the volume header creation date.

Now the question is, will this be a constant repair cycle? The old Time Machine hard links have already been repaired, so they won't need to be fixed again, even after DW repairs the root date.

If I manually create a hard link on the backup volume, it gets created with whatever the current root date is, so if it is after a SD clone, that link will get repaired by DW.

I haven't figured out whether Time Machine will create new "bad" hard links. It doesn't seem to, but I don't know why not. Maybe I'm not looking in the right place.

The other case would be if a SuperDuper creates a new hard link on the destination drive, because it now exists on the source drive. I don't know what it is going to do in this case.
