Tar with permission preservation is fine. Just exlude everything in
dev/sys/proc/tmp as you said. But make sure, that these directories are
in your tar file, it does not matter if they are empty, but they have to
exist in order to boot proplery.

One special case. To boot you most likely will need /dev/console and
/dev/null. Just inlcude those two device nodes in your tar file.

Optionally use compression (gz, bz2, xz, ...) on your tar to safe some
space.
