    RAID is not a backup solution, It is an *availability* solution

    If you want to *preserve* data against drive failure, back it up
    on another drive.
    If you want it *available* with a drive failure, use RAID. And be
    prepared for it being unreadable if a controller fails.

    If you really want disaster recovery you need your data in two
    places.

    I keep a backup of my important stuff in a drive in my bedside
    drawer. The machine lives in my garden office. It would take a lot
    to destroy both buildings.


    It doesn't matter what solution to data back up is proposed someone
    will always come along & say "But what if ......"

    To which the correct answer is 'then data loss is the least of your
    worries..
