What is the best bullet-proof backup scheme for about 2TB of data? (Pictures, movies, etc.)?

Drobo's a pretty solid and super easy to use storage solution, and scalable up to just about any size. drobo.com/ engadget.com/2008/07/08/drobo-second-gen... You just put a bunch of hard drives in the machine, and it'll do all the redundant cross backups on all them. Even if 2 drives fail at the same time, your data will be safe.

You might also want to use an online solution for your more precious data, that way if your house caught fire, you'd still have your data online. It's a pretty good way of backing up stuff online, and they have a 15 day trial. carbonite.com/ Amazon's S3 service also works for online backup.

aws.amazon.com/s3.

It depends, if you want it for backup only then magnetic tape stored in a different building would be the most cost effective choice with a weekly full backup and daily incremental. If you mean so if a hard drive fails you won't lose data, then I suggest getting 3 1TB hard disk drives and linking them in RAID 5 configuration, or 4 drives in RAID 1(mirrored). (5 is cheaper, 1 is safer) for higher access speeds a raid 1+0 or 0+1 array with smaller individual disk sizes would work best.(I recommed combining the raid setup with the magnetic tape option or an over the net backup as per the magnetic tape option to a web based backup service.).

Wrong thread sorry. You posted another question about a company name...? I clicked send and it placed the answer here. I am not sure why.

I would vote for Amazon S3. You have a flexibility when it comes to choosing your desktop client. There are many clients available.My company is a provider of a freeware Windows client called CloudBerry Explorer cloudberrylab.com/ , it fits more sophisticated users, but there are many other clients available.

We are also working on a consumer facing client - CloudBerryDrive. You can sign-up for beta on our website. cloudberrydrive.

I agree with him about the Drobo. However, if that's out of your price range, a few good solid USB hard drives will do, along with some good online storage. The Apple Time Capsule router has a server-grade hard drive built in, and also integrates with Time Machine (a great backup program built into Mac OSX Leopard) For a near-bulletproof backup solution, alternate drives each backup.

One tip I found in an old programming book: Use 3 disks. Save to disk A the first time you backup, then disk B, then A, then B, A, B, and finally C. A and B contain the two most recent backups of your data, and C contains a backup backup in case A and B fail.

Time Machine is a great backup program if you have a Mac, but it only backs up to: Mac-formatted drives connected to your computer, Mac-formatted drives connected to another computer running Leopard, the Time Capsule, a drive connected to the USB port on the Time Capsule, or a drive connected to the USB port on an AirPort Extreme. However, what makes it really great is that it makes automatic backups every hour, saves each revision of each file, and allows you to restore individual files. For Windows, you really need a good backup scheduler software such as Acronis.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
