Hey,

  Something simple like this to save
# find . -printf '%p %m \n' > permissions.out
  Then something like this to restore
# awk '{system("chmod "$2" "$1)}' permissions.out

  Simple, easy to read, plaintext backup.
  It wouldn't be hard to add ownership to this if you want/need that too.

# find . -printf '%p %m %u %g \n' > permissions.out
# awk '{system("chmod "$2" "$1), system("chown "$3":"$4"
"$1)}' permissions.out

  This doesn't support filenames with spaces as it stands, but hopefully
works as a proof of concept...

cheers,
Owen.
