Creating an Archive folder as he describes doesn't stop Time Machine from creating all those hard links everytime it runs-so his solution doesn't fix anything.
He should upgrade to a faster disk for his backup to solve his issues. I have a very large collection of mailboxes on my machine and see none of these issues he's describing.
- emordnilap 17y agoI think he meant that making a hard link and copying a small file take about the same time (when storing emails as individual files.) I think the archive folder idea is a workaround for Entourage. If you have one large file that rarely changes, then making a hard link to it would be much faster than copying it.
- mjtsai 17y agoCreating an archive folder does help because then Time Machine can create one hard link for the directory rather than a folder containing thousands of hard links to individual message files. The archive folder is for Apple Mail, not Entourage. Entourage stores all the mail in a single database so it doesn't matter which folders the messages are in.
- tesseract 17y agoTraditionally (and even now in most unices) hard links to directories were not allowed, in order to prevent endless recursive cases. Apple added the feature to HFS+ in 10.5 so that Time Machine could make use of the optimization you describe. There are rules about directory hard links so that pathological recursion still cannot happen: http://lists.apple.com/archives/darwin-dev/2007/Dec/msg00029.html http://lists.apple.com/archives/darwin-dev/2007/Dec/msg00029...
- xenophanes 17y agoif nothing in a folder changed, then the individual files aren't hardlinked. if you dump 5k files into an archive folder, then assuming your inbox has an update, and the archive folder doesn't, it's 5k less hardlinks being made.
