can I preserve UIDs/GIDs when transferring with rsync?

I noticed that rsync can preserve most of the file's characteristics
when it is used with "-a" option (it includes -o and -g flags for
preserving owners and groups).
However, when I transfer data between systems, it affects my UIDs/GIDs,
making the data hard to recover.
-rw-rw-r-- 1 mark mark 19525 Jun 23 2004
-rw-rw-r-- 1 mark mark 19525 Jun 23 2004 /backup/users/home/somefile.txt
But in reality, UID and GID of that file changed from 503:503 to 659:103.
It is a big obstacle in my backup system.
Is it possible to transfer files with rsync, and to preserve the *exact*
UIDs and GIDs, rather than usernames/groupnames (which in turn point to
invalid UIDs and GIDs)?
