Manual: Time Machine using 2 hard-drive (different models to lower probability of both going down at the same time), one at work, one at home (I sync mainly when Time Machine nudge me every 10 days), which takes care of "something burns down" scenario. Also, a separate hard-drive for sizable personal media (raw photos/videos I don't intend to use soon), which is the only weak point (I should research Amazon Glacier or similar technology) Automated: all important work also lives online (Github for code, Google Drive for documents, Gmail keeps all conversation). Apart from the media hard-drive, I think this follows the 3-2-1 rule for back-up: - Have at least three copies of your data. (3 full copies, fragmented data online) - Store the copies on two different media. (2 HD, 1 SSD, online) - Keep one backup copy offsite. (2 full copies at different sites)
