Hi Mishka You should think again about how RAID storage works:
Raid 1 writes/deletes simultaneous on 2 mirrored drives, so it is *not* the same as having two separate copies of a file. The more drives you involve in a system, the higher the possible error rate gets. A fail of 2 drives in a Raid 5 system at the same time destroys all your data. Raid systems are made more for speed and nonstop operation in networked server environments than anything else imho. And I can only repeat it again and maybe even the lazy and "easy going" persons here better believe it: You have to safe several generations of your data on different non rewritable mediums stored on different places to be "quite" safe. Everything else is asking for trouble with your data sooner or later. This is my last word on data backup, it's starting to get redundant :-) greetings Markus >>-----Original Message----- >>From: Mishka [mailto:[EMAIL PROTECTED] >>Sent: Monday, August 01, 2005 2:32 AM >>To: [email protected] >>Subject: Re: Backing Up and Storing Files >> >> >>the word "backup" usually implies some kind of reliability. hard drives >>are not. >> >>it would be *ok* if you kept a *second copy* of each file there. >>but that's in effect RAID 1 where you do what RAID controller does: >>making sure you have two copies of everything. >> >>at this point, i am keeping two copies of everything, one on HD and >>one on DVDs stored away in the basement. this is pretty far from >>perfect, so at the same time trying to find a way to come up with cash >>to get a real RAID-5 storage system (unfortunately little boys >>don't fetch >>nearly as much as girls...) >> >>mishka >> >>On 7/30/05, Shel Belinkoff <[EMAIL PROTECTED]> wrote: >>> I've not a clue as to what your point is.
