Was told that storing your photos on cd was the way to go for archiving, the guy who fixes my computer told me that this only stores the image for a couple of years. after that it starts to degrade due to moisture storage condition etc can anyone share some light on this

He is right about the fact that it is generally only good for a limited amount of time, although that time is more likely longer than what was mentioned. Much depends on the quality of the CDs that you archive to. The reason has to do with the dye used in the layers of the cd. That is what gives the CD its color when you look at the recordable side. The dye will fade over time (much faster if left exposed to the sun). Some 'experts' say that the average disks are good for a few years at best. There are disks that have special dyes and are deemed to be 'archive quality', sometimes gold in color and termed 'gold disks'. The manufacturers claim that they will last up to 100 years. Google 'archive quality cd' and you should find retailers and manufacturers of the good ones, but hang on to your wallet. They're expensive.

See, http://en.wikipedia.org/wiki/CD-R#Op...ected_lifespan

Some archive quality (aka very expensive) disks claim a lifespan of 100+ years.

But that depends on how you store them.

A cool, darkened room, average to low humidity , stored vertically , no excessive handling especially the surfaces with greasy fingers, nostuck on paper labels, you should have decades..

Lying beside a radiator ? High humidity ? Umm....

I see those, but 650mb is unacceptably small of a size for backing up photos these days, it's not even half the size of my CF card. I see they've also got DVD's which though ~$150 are only $3 a piece and hold 4.7gb. (or for double the price you get a bit overseven times the capacity) The only issue with their DVD's is that they have no test data to tell you how long they'll last. (and I'm not buying $150 in DVD's thatwon't outlast$30 DVD's)

I can use CD's for certain storage needs (one shoot in jpeg perhaps) but for far too many things I now need DVD-R and even DVD-DL. (speaking of which, Memorex DVD-DL = junk, Verbatim DVD-DL= good)

I back up every picture file on my HDD every day to a seperate HDD and to DVD-DL every 3 months or so.It's not super expensive but It's a bit wasteful. I've considered only backing up new data to the DVD, but that would reqiure more time investment than a $3 dvd really demands IMO.

My vote goes to hard disk drives. Yes, they have moving parts that can fail. But, other media develops problems, too.

IMO, the "trick" is to make sure you've got images stored in more than one place in the event of a failure (and they do happen), making sure to transfer your images to newer media periodically (for example, newer hard disk drives from time to time).

You know the 'geeky' among us are probably the most likely to give GOOD ADVICE to others (not here, but on the job) and yet NOT DO IT OURSELVES. (Speaking of myself of course.)
