I used to use that too but I couldn't work out what it does that cp -a or rsync -aHAX don't (in fact I think rsync -aHAX might even do a more complete job of preservation than tar). Anyone know the differences?
Actually tar, cp and rsync will probably all need the --one-file-system option too to keep from recursive badness.
