I hope I never have to deal with a situation where all of my computer data has been lost. Luckily, there is now an active industry for disaster recovery, which didn’t exist when computers first started becoming an item in every household. I have never had to deal with it, so I’m not sure how much having to take your personal computer to an expert for this would cost. And I definitely would love to know the difference between disaster recovery for a personal computer from recovery of an entire network of computers. It’s pretty safe to assume that dealing with personal computers is far less expensive then having to deal with a network recovery. Even if the expert dealing with it only has to recover data from one computer to retrieve the data for the rest of them, it would not make much sense for it to be a similar cost to fixing a personal computer. I think my best bet is to make sure I never have to worry about it for my personal computer at all; it’s best for me to take preventative steps right now to ensure I never have to worry about having my computer serviced.
