Well, that's wrong then. 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.
I can see reasons for both ways.
cp, tar, and friends would "create" a copy (a different creation date)
Except that tar *does* maintain creation dates.
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.
