Just came across this article on the BBC about a popular flight simulation site that was hacked. Apparently their only means of backup was to copy the data between their two servers. Unfortunately for them, the “hackers” got in to both servers and destroyed the data. Approximately 13 years worth of work that now cannot be recovered. While I feel sorry for the owners of the site and hope that they can get much of their information back through Archive.org or Google Cache, the whole thing could probably have been prevented with a small investment in to an offline backup strategy.
