I have archived many VHS cassettes onto DVDs but I al under the impression that DVD's don't last forever. Should I be backing my media up every 5 years (etc?) Some of the things I have recorded are, well, irreplaceable. So, question is how often should I make back up copies so I can keep watching stuff that is special to me.
No, they don't last forever, even if the manufacturers want you to believe that. As far as I know, there isn't a specific life span for home burned CD/DVDs because there are just too many variables at play. I think if you have valuable data, it would be very wise to re-backup it just as you suggested (once in 5years or so). Choose good quality discs as well. This might be interesting (and check the links in that article as well): http://blogs.guardian.co.uk/askjack/2008/05/how_long_should_a_dvd_last.html Edited by - Zoid on 6/8/2008 5:44:14 PM

So maybe backing up every 5 years is a smart thing to do?

This article says 2 to 5 years [link removed: No link shorterners] This one says 20 years [link removed: No link shorterners] And this one explains why it is so unpredictable. [link removed: No link shorterners] The geeks at CD Freaks http://club.cdfreaks.com/ consider it to be less than 10 years and agree (for the most part) that Verbatim DVDs are the best quality. How you store them is probably equally as important.
I don't know. They can last a really long time or they can die a week after you burn them. All you can do is check around and see what's generally regarded as the best blank media and make backup copies of anything that's really important. Don't ever trust one disc with anything of value. Personally, I wouldn't trust CDs or DVDs at all with anything priceless. Hard drives are cheap enough and (generally) far more reliable. If you have a lot of stuff you can't afford to lose, I'd get a couple of extra hard drives and store a copy on each drive. And then, maybe a copy on a good brand of DVD just for that little extra measure of protection. I've been using CDs and hard drives for 8 years and I've lost so much good stuff because of CDs just being what they are (shit, generally) that I just don't trust them for anything I can't afford to lose. I'm sure I've probably just been lucky but I haven't had a hard drive die on me yet. And I use the shit out of my hard drives and am not especially careful with them. I've left my computer running for weeks on end. I'm not saying to trust one hard drive either. Never trust one of any storage media. The chances of two hard drives dying at the same time are probably pretty damn low. I'm sure it happens but at least you could say you were a victim of a freakish event and you did everything you realistically could to prevent losing something that was irreplaceable.

^^^^ I have read that also. My question is how long they retain data before wearing out/degrading. TYPO Edited by - conquistador on 6/10/2008 12:15:12 AM
some burners allow you to run scans on burned discs, some people scan their discs regularly, if the errors are increasing, reburning would be prudent. TYs and Verbs usually degrade the least, the general advice is to stay away from all the other brands like Maxell, TDK, etc and especially Memorex. It might be a good idea to scan and reburn if necessary every 3-4 years or so.

The discs I am using right now say "Berkely & Jenson" on them.
i love reading these old tech threads. i get such a kick out of the outdated formats and technology posts lol. however, i must say my earliest collected scenes were burnt to data cd's going on 20 years now and every one i have used has worked perfectly to this day. all types of brands from sony to generic not one has failed. nowadays i pop in a disc and just move the files to whichever large external storage device i have plugged in and watch from there. so strictly as a storage medium discs and dvd's have held up fine for 20 years now. anyone else still have their old data dvds and cd's?
