Do I need to do a backup?

what to backup to, for me its DVD/CD ,i don't own any 12 year old harddrive .but i still have some files on 12 year old CD's

Backing up on DVD - no way. My images are 25GB on average. You imagine the mess with DVDs. Plus I do that 3 times per week. Do I need images that are 12 years old ??

For a limited number of precious documents and very special photos you should backup to multiple sources and a drag & drop to some DVDs is ok for one of the sources (as far as I'm concerned). Even then you may want archive quality DVDs ($$).
But for general backup and system imaging I would recommend ext HDDs preferably USB3 for speed. I use 2 ext HDDs in case one fails.

obvious, i didn't mean you lol . mine are usually only 3 or 4 gig ,so i guess it only applies to myself ,
i need the images from 12 years ago more that the ones from last week ,those i could take over again anytime ,not so for the 12 yr old ones,to each there own i guess
