Do Burned CDs Have a Short Life Span? – Yahoo! News
Quote: “Unlike pressed original CDs, burned CDs have a relatively short life span of between two to five years, depending on the quality of the CD,” Gerecke says.
I learned about the short lifespan a couple of years ago, and I’ve been trying to spread the word. So this article, which is rather boring, serves as a good reminder—CDRs do not last.
What’s the best way to keep your documents and other data longterm?
My recommendations:
1. Get a second hard drive: They’re getting cheaper now, and usually there’s plenty of room to store copies of software you download, as well as digital music—and the documents you want to keep. Having a second copy (one on each hard drive) means you have an easily accessible backup in case one hard drive crashes. (Of course, if the computer is stolen, burns, or otherwise becomes wholly inaccessible, both copies are lost)
2. Annual checkups: Go ahead and burn those CDRs, but check them annually, and burn new copies of the most important things. At least check every two years… But burn multiple copies of important documents, in particular. As technologies progress, DVDs hold several CDRs – so what once took several CDRs might take only one or two DVDs. Of course, you’ll accumulate more and larger data over time, but the storage media will grow as well….
3. Online storage: Google gives a large amount of space—emailing important documents to your Gmail address is a good option. However, as a free service that might disappear at any time, it shouldn’t be your sole option—but none of these are intended as total solutions. In addition to free services like Google, I’m developing a (paid) internet storage solution. (The project I’m working on will allow you to map an ‘internetwork drive’ – a drive you can access via Windows like any other drive on your computer, but that will be pysically located on my server, thus giving you storage outside your home that you can easily access from your home—or anywhere).
I don’t recommend a single one of these options—the more important the data is, the more options you should use. Something very important, like digital (or scanned) photos of a life-changing event (e.g. wedding, etc) that simply cannot be replaced should get the most attention. I would consider having one set on your primary hard drive, one set on your secondary hard drive, a couple of burned (CDR) copies, as well as a copy stored offsite somewhere.
But for things that are important, but less important—you might choose only one or two backup methods… I’ve taken a number of digital pictures that are important to me, but that wouldn’t completely depress me for months if I lost them. So I might store them on both hard drives and on my server, and decide that’s enough…
Point is – match the effort to the importance; and take the time to make whatever backups you think are needed. Your hard drive will crash some day; your CDRs will become unreadable—times are changing, and you need to consider how to make the data you want to keep available for the future.
The good news is that it’s not really hard.
(Feel free to contact me if you’re interested in the internetwork drive I mentioned – setup is easy, and I’m still in beta testing mode; if the service does go fullblown live, my beta testers will get cheap or free services in thanks for testing…)
