This is a followup to my recent column about Steve Wozniak’s warning on the perils of cloud computing, especially cloud storage. It might surprise many users to know there are firms that sell cloud storage and do not back it up. They rely on the disk RAID and some redundancy in the cloud to “protect” your data. If something happens to their data center, they could probably not recover your data.
Remember MailandNews.com? They did not have a viable business model. They also didn’t back up their servers. One day they had a big crash and relied on the RAID array to recover the data. It took two weeks and still not all of the data was recovered.
RAID is not a data backup technology.
