    A RAID1,5 or 10 is perfectly fine for backups.....ive been using them for years now. When one of the platters died there was no frying of other disks, or other electical wizardry.....not entirely sure where that comes from


    You should have an external backup to USB too.

    You can't protect against every eventuality....if thats how you look at it, you may as well stop using computers and go live under a rock. The goal after all is to enjoy computing, and not spend ing your entire life trying to insure against every possible scenario, including the very unlikely.

    This is the kind of thing that constantly amazes me, especially coming from someone who has forgotten more about computers than I will ever know and should know better (they don't give the MS Community Contributor Award to anyone unless they are extremely knowledgeable).

    There is nothing wrong with using RAID to ensure continuity of operation when one of the disks dies but it cannot, I repeat, cannot be depended on for a backup. Just because you have been lucky doesn't mean RAID is a reliable backup.

    I do not appreciate your misquoting me and mocking what I had said with the "electical wizardry" crack. I never said anything about a dying platter frying any other disks. If you had paid attention to what I had written, you would know "where that comes from". What I mentioned was a failing PSU could fry all the disks. PSUs can fail, frequently catastrophically, and can fry every component in a computer. I've read many reports of that very thing happening so I'm not pulling this out of my ear. And don't roll your eyes at me young man.

    I frequently see posts here and on other forums about people crying that they lost all their data because the drive died, a virus damaged or wiped their data, or they accidentally deleted their data. If there is only one copy of one's data, such as on a RAID or a single drive, it is not backed up. I've already pointed out what can cause data to be lost when depending on a RAID; I suggest you go back to my post and read it carefully, this time with an open mind.

    No, one can't protect against every possible scenario but that doesn't mean one can't try to minimize the chances of losing one's data. It's not that difficult. And it's the unlikely scenarios that will bite you in the backside. And before you start complaining about the expense of a proper backup, consider the expense of recovering or replacing lost data, if it can even be recovered or replaced.

    At least you did get it right when you advised also using an external USB drive.

    Sheesh calm down already . In my experience there are many ways to mitigate against data loss, and some of them dont require extreme practices at all. A functioning RAID 1.5 or 10, with an option of external storage is as good as a more extreme version. I work with very large and very valuable datasets, but I try to enjoy that without worrying about too much about whether my backup of my backup of my backup is sufficient. There are many ways to skin a cat, but they dont all require precision surgery.
