I think I might not have conveyed my original point very well. Some posters are very defensive of raid and may mistakenly believe that I was discounting as a potential solution. All I was really trying to say (somewhat clumsily) was that what a raid setup protects you you from that any other solution (LVM, JBOD, single disk) combined with regular backups doesn't is downtime in the event of a physical disk failure, since you can rebuild the array from parity (assuming you have a replacement disk) without having to do a complete restore. I just wanted to suggest that for some users, the time it takes to restore from backup to get the data back may not be a problem, and might be worth the almost mindless simplicity of setting up LVM. Personally I am a raid user (though not at the moment) and I think various raid configuration s have some pretty neat implications. I just wanted add another idea that may be viable in some circumstances. Sorry for any confusion.
