Further to this: a RAID is no infallible substitute for a backup of critical data. A dying controller can write rubbish to your disks silently for days - even if you just get a straightforward controller failure, you then have to treat all data as potentially suspect for corruption. Andy - who has lost one RAID to a controller failure and another to a failure of one disk and unacceptable throughput - both in the space of about two weeks - both afer about 18 months light-ish use. If you have vital data, back it up into two or three places. If it's small enough, back it up onto two or three different types of media - DVD-ROM, cheap flash drive _AND_ backup to hard disk somewhere. If it's a document, save a copy in ASCII and/or print it. Have a good friend / family member store some for you in their house - cheap "offsite" - on condition you store some for him/her. Periodically, check you can get data back. This is the counsel of perfection - no one EVER follows it - but if it saves someone's online life, business , marriage or whatever, it'll be worth it :) All best, AndyC > > -- hendrik > > > -- > To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org > with a subject of "unsubscribe".
