If your video files are already on an internal hard drive, I'd only bother withy multiple backups if they're super important to you.[/QUOTE]

if the film is not out-of -print , or obscure- it's often almost cheaper to pick up another copy of the original, than to invest in all the disc space needed for multiple backup copies!

Many films can now be found on ebay or amazon marketplace priced as cheaply as blank media!
