I wrote a tar that knows how to read filesystems right off the raw
disk, a la dump, which allows it to (a) back things up without touching
even the ctimes and (b) handle files with holes 100% right. (It's the
only program I know of that does as well as possible on the Zwicky
tests - the only tests it gets at all wrong are the ones involving
things changing during the dump.)
Now, this code is of course filesystem-specific, and the code that's
there is for ffs. But I know someone who's got ext2fs support for that
thing in progress (he works at a site that uses the ffs version for
their routine backups, and wants to do their Linux machines too).
Once this exists, it should be an option - I'm definitely going to roll
it back into my sources, and as always, anyone who wants a copy need
but ask for it.
