Ok, if youre not satisfied with copydir, then maybe you can use something
from my script below.

# upd.mirror tries to do the same as mirror/mirrordir,
# but the files are transferred via tape
# or more specifically:
# it tries to make a source and a destination directory tree be identical
# and when the source and the destination are on different hosts
# and when a direct network connection is not usable but we can excange e.g.
tapes
# two files are identical when:
# they have the same content (or as an approximation the same md5sum)
# they have the same size, permissions, uid, gid, and modify date
# they have the same name and the same location within the tree
# this program ignores pipe, socket, char and block special files
# we assume two files are the same when command below gives same output:
# ordinary files:
# ls -l --full-time | cut -b-11,17-
# i.e. omit #links field, and make ls independant of when it is run
# directories:
# ls -ld --full-time | cut -b-11,17-34,69-
# same permission, uid, gid and name, ignore #links, size, and mdate
# symbolic links:
# ls -l --full-time | cut -b17-43,69-
# i.e. (omit permission and date) they have the same size, uid, gid and it
points to the same file
# hard links (treated like ordinary files, tar/cpio takes care of theese)
# we quietly assume size < 99999999
