I am not familiar with the rsyncz command. Is it some variation on the
rsync command like the rsyncX command that Apple folks use under MacOS X
to deal with the extras like resource forks that may be present in the
HFS+ filesystem?

- -a is shorthand for -rlptgoD on the rsync command-line.
(aka --recursive --links --perms --times --group --owner --devices)

Well, the --update switch would not let you incrementally improve your
destinationpath with the lastest changes. It would probably be okay for
a one-shot as long as you didn't get an exit 24 return code which means
that something was not properly copied.

I do not believe there is any single right way. There are many
possibilities. If your 'cp' command has a -p (preserve) flag, then I
suspect it may have been a slightly better approach. Even so, the 'cp'
is likely going to change the owner of the restored files unless you are
running it as root.

You could have used the same basic rsync command:

  rsync -auvz destinationpath/module srcpath/module

to do your restore.
