My sister is writing her thesis that is almost complete, she called me yesterday early morning to ask for help, her laptop had lost display. This was an issue with HDD as changing the HDD fixed the laptop. Luckily her brother knows the stuff and he recovered her data after replacing board of HDD. Took me 2 days, she was scold off by me, I am the elder one :) for not backing up her data at alternate location.
So, what i the best strategy to back up day to day work on documents ..for novice users ..
