what is the thinking of using a memory stick as a back up for the computer?

If you can actually fit all your HDD contents onto flash drives, then more power to you. As with any backup, you'll want multiple redundant copies at multiple sites. I'd still use DVD's, because they're cheaper. But I would like to know, what is the lifetime of a flash drive w/o being plugged into computer?? Do they need any kind of re-charging?? This question made me think about it & I can't find much data...anybody else know ??

I'd be more inclined to stick with CD/DVD media; usb sticks are very vulnerable - easy to lose, tread on/crush etc...? usb sticks are convenient way to transport data aroudn on a temp basis - but "long-term" storage...? And if being really keen... have a duplicate hard-drive storage system too...

Memory sticks/USB keys etc are a NON-volatile form of data storage. In other words, once the data is written to the device, barring any physical damage or electrostatic discharge happening to the device, your data is as safe on it as it is on a hard drive that is not installed in a computer. CDs and DVDs do degrade over time if subjected to extreme environmental conditions (heat especially), chemicals (some permanent markers and household cleaning supplies) and general wear and tear of storage, transport and use. NO medium is GUARANTEED. If you have extremely critical data to backup it is always best to make at least TWO backups; one to keep onsite nearby to be used for restoring in case of system failure and the other copy to keep offsite in a lockbox, safety deposit box etc as a backup to your backup. USB drives are no more risky than any other device or medium for storing data; just be sure to take care of ANYthing you use to do so. Who gave you people access to a computer?

actually, I meant a flash drive. How about that for a back up?

same thing as usb-memory stick is it not?

I thought so, trv... USB stick, flash drive, thumb drive.. Same thing, no? Life's more painless for the brainless.
