Editorial Now that everything is moving to the cloud internet, you might think that data loss is a thing of the past. Sadly, as the past few months have taught us, this actually isn't true; we first had the Microsoft/Danger disaster, and now we have Palm and Sprint facing a class-action lawsuit over data loss for webOS phones. All this raises the question: how safe is it to store your precious data on the internet, and do you really trust the internet?

Safe guarding your data

RAID is a backup solution against hardware failures. They happen, but most data loss is about user mistakes.
You should have a backup for important data from the past so you can get back in time when you or someone does something stupid with your data. And make sure you backups at several points in time in case you or someone does something stupid with your backup data.

Now what support can you trust to keep your data? Answer: none. All supports have failures. The cloud, the hard drive, and the DVD all have failures and will always have failures. Simply put, you can't have your data 100% safe. What you can do is mitigate the risk.

So let's say the cloud has a 0.01% failure rate (let's say that 1 user looses all of his data every year for 10000 users using the service). And let's say your hard drive also has 0.01% failure rate. Now if you copy your data both on the cloud and on the hard drive, your data loss risk is greatly mitigated: 0.01% * 0.01% = 0.0001%. Now if you copy your data to DVD and the DVD also have 0.01% failure rate, you are down to 0.000001%.

Bottom line: when you copy your data somewhere, you reduce your risk of loosing your data dramatically. The cloud is not the perfect, but it still reduces your risks.

The privacy issue is a completely different topic.
