Most people I know do not have any plan to backup their data. Somehow they put their trust to a piece of 3.5″ glass disc, spinning at 5400 times a second or more with a sharp metal spike fraction of a hair above it. Me? I like to spread my risk and backup my data, especially after suffering a total data lost about 12 years ago. As Alex Lindsay from the PixelCorps often says on podcasts, “Unless the data is stored in 3 different places, it doesn’t exist”. This may sound over the top but with all the online file sharing or storage services available it is actually pretty easy to have decent backup strategy with minimum cost. To achieve comprehensive backup coverage, it would definitely cost a few dollars.
Like computer security, any backup strategy should be constructed in layers. This applies to both time, location, and accessibility. Let me use my backup strategy as an example.
