Can someone recommend an "easy" disaster recovery solution for an openSUSE system running MD RAID 0? Ideally I could tell a computer-illiterate person to insert a DVD, press "yes" at the prompt and everything will be restored to a default state. --
By MD RAID 0, I assume you mean software raid? (lets be precise here). You have virtually nothing in the way of disaster recovery with Raid 0, loss of either disk means your data is gone forever. So I don't see any "Insert the DVD" sort of solution here. Even with a full backup you would have to potentially repair the failed disk then do a restore. And if your system was on the raid-0 (as opposed to just your data) you are right back to doing a bare metal install. With Raid 1 you get mirroring and you can lose one disk with no data loss. You can recover from that fairly easily (in fact I have lost one disk of a mirror and didn't even notice. I've since started using monitoring). Disaster recovery is seldom as easy as shoving in a dvd. That's why they use the term "disaster". -- ----------JSA--------- There are 10 kinds of people in this world, those that can read binary and those that can't. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
