I've googled this one for a while and can't find any examples of people doing *system* file sync with rsync. So I thought I'd throw it out to the collective wisdom of SLUG. Here's the full story.
We have a SuSE-based production application/DB server pair and a corresponding pair in a disaster recovery location (offsite, bandwidth consumption needs to be minimised). We need to sync a number of files between these servers and some require elevated (root) privileges at *both* ends. Here lies the problem; we don't allow remote root logins (via SSH or any other method either...sudo, console or nadda).
I want to use rsync because of it's ability to transfer differential/incremental changes and thus bandwidth friendly, however any other tool would be fine too. However, due to the inability for root to login directly, how the heck do I synchronise particular files in privileged locations (like /etc/shadow)? I can start whatever services I need at either end (like an rsync server) but the main thing is all files maintain the same owner/group/mode at each end.
Thanks in advance,
