The rsync source package comes with a Perl tool to reapply attributes of your
choice (permissions, user owners, and/or group owners), which you can also find
here: http://rsync.samba.org/ftp/unpacked/rsync/support/file-attr-restore . 
The corresponding attribute-saving tool is just "find . -ls".

Another alternative you might consider is using rdiff-backup (
http://www.nongnu.org/rdiff-backup/ ).  It makes a backup zone containing a
full tree of the most recent backup, a separate listing of all the original
attributes (so they are known if the attributes on the backup tree are never
set or get corrupted), and a chain of backward deltas of files and attributes
for previous backups.  The advantage is that you get data and attributes for
all backups in less space than with rsync --link-dest; the disadvantage is
that, to restore files from a previous backup, you have to go through
rdiff-backup rather than copying the files out directly.
