Like many people I used to back up my files on flash dirves. It was never a good solution. You’d have to back up files manually – and of course sometimes you’d forget to do it. And if you took the flash drive anywhere there was always the fear of losing it
Now online storage services like Synchronity and Dropbox are making backup a lot easier and providing a sense of security. They back up the files automatically and you have access to the files online. The one I settled on is Synchronity. It’s free up to 2 Gigs. Then only $9.99 for a month for up to 50 gigs. What a relief.
