zip and some of the other compression tools also have a habbit
of not preserving file system permissions or ownership, which can
be handy in a backup, also may not support special devices(e.g.
sockets, fifos, character/block device entries etc). If you rely
upon file system ACLs on top of regular unix permissions things
might get more complicated, I don't use ACLs, so don't have
experience with preserving them in archives.
