During a thunder storm my computer was destroyed and I just had to get a new one as soon as possible. Luckily the company I use to buy from could save the data I had on the hard drive. Nowadays I have one extra hard drive and take backups regularily, but to be honest it could be more often! So when I saw the ad from my security program, F-secure, I decided to pay for the service and always get instant backups. Not sure how it works but I can see that almost immediately when I create a document the program copies the file, there is a little dot next to the name of the file.
