A Backup /must be/ identical to the source in every possible respect otherwise it can not be used to properly restore said file to it's original state. cp, tar, and friends would "create" a copy (a different creation date) To preserve creation date, one would use a filesystem dump(8)/restore(8) utility. That's a physical backup. I'm not even sure dump works at all under OS X, it's been a while since I checked it but it didn't used to. Analgous here would be saying the only way to maintain all file properties on a volume is via `dd` I see that Mac OS X has dump/restore from FreeBSD. I have not yet used this facility for HFS+ volumes. Does it preserve the all the attributes/metadata/whatever? Creation times? As I said it's been a couple of versions of OS X since I checked but it didn't used to work well at all. -- This email sent to site_archiver@lists.apple.com
