I do this using gmirror; I run a two-disk Raid1 system for normal operaton, and back up to a third device which a CRON job attaches and detaches nightly to image the system. The detached disk is removed, so it will not be detected as a valid device on boot. If the online mirror breaks (either disk) the other continues on its merry way. In a catastrophe where the system scribbles on BOTH disks, the other volume can be booted manually and with a bit of effort (couple of command-line entries from single user mode) brought online as a single device. -- -- Karl Denninger ([EMAIL PROTECTED]) Internet Consultant & Kids Rights Activist http://www.denninger.net My home on the net - links to everything I do! http://scubaforum.org Your UNCENSORED place to talk about DIVING! http://www.spamcuda.net SPAM FREE mailboxes - FREE FOR A LIMITED TIME! http://genesis3.blogspot.com Musings Of A Sentient Mind _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
