I would argue that the way it works with Unix and Linux is way worse: only the latest "version" of permissions is stored. Yes, it's nice that something like "chgrp -R foo /large/tree" does not trigger a huge backup, but I almost consider it to be a fundamental design flaw of TSM that you cannot restore old permissions on POSIX platforms.
