[SLE] backup disks

I have a system with two disks, each with some space, so I'm contemplating backing up the contents of each onto the other. I'd prefer a system that just mirrored the files, rather than consolidate them into an archive. Then I'll just update the mirrors each day. Any ideas on what the best way to do this is (cp -a, rsync ??) or suggestions as to a better alternative? Thanks, Dave PS I already have a 'system' configuration backup through the YaST mechanism, though it hung after it had finished, it appears complete. -- Check the headers for your unsubscription address For additional commands send e-mail to suse-linux-e-help@suse.com Also check the archives at http://lists.suse.com Please read the FAQs: suse-linux-e-faq@suse.com
