Several months ago one of my family members purchased a brand new MacBook Air for the purposes of going to university. This morning I received sad news that said laptop had been lost. Thankfully the laptop was insured so at least the physical value of the laptop should not be an issue. Lesson One: Make Sure Your Laptop Is Insured For Both Accidental Damage And Loss! However what happens with the data which is on it? The truth is that there is no excuse for not having mission critical data (such as university work, important account files etc etc) backed up as it is changed. This is possible through services such as Dropbox and SugarSync, which are free and monitor folders and files and automatically upload changes to the cloud. Lesson Two: Sign Up To Dropbox And/Or SugarSync! Passwords, need to be safe and secure. In other words unique and ideally containing random letters as well as characters which are not alpha-numeric. This isn’t a daunting process as 1Password has it covered. 1Password is covered in detail in my ‘Useful Software & Services For The 21st Century Student‘ post. It is more expensive than the average app, however its an investment that will keep your banking details, and other secure login sites safe. Lesson Three: Make Sure You Don’t Use The Same Password, Or Simple Passwords For Anything! All of this advice is to protect you from losing your laptop or computer as a result of carelessness of theft. But it should also be followed generally as the hard drives which your data is stored will not last forever. I have suffered two hard drive failures around 7 years ago where my data was not backed up, and it was horrendous. Memories gone, important documents lost, hours taken to rebuild what I could. As anyone who has suffered a hard drive failure or computer loss will tell you, although the physical computer can be replaced, the memories contained on it usually cannot.
