I'm not sure how many times I've mentioned in columns how important it is to back up your files. When disaster strikes in the form of a bad hard drive you'll be glad you did. I've had to tell mothers that they have lost all the pictures of their kids. I've had to tell businesses they will have to recreate their books and other financial data. Believe me, it is not a pleasant time for any involved. A hard drive can last for the life of a computer. It can also crash after a few months or a couple of years. And remember, backup is where you store your stuff in two places, not just move it from your computer. So what are your options for backup? CD/DVD: This method is proven and creates a physical hard copy of your data. The only problem is it takes a long time and can be difficult. CDs and DVDs also have limited space. The harder it is the less likely you will do it on a regular basis. Flash Drive/Pen Drive: These handy devices hold more and are much easier and faster to use. They are inexpensive and re-writable, meaning you can delete old backups and replace them with new. The down side, these devices can fail. However, the odds of them failing at the same time as your hard drive are slim. External Hard Drive: See above, only a lot more storage room. These are for people with lots of pictures, music and other files they want to save. Cloud Storage: You can use services like Dropbox, Google Drive or any of the other popular cloud storage solutions which will do the legwork for you on the background. Backing up to the cloud can be done seamlessly and easily which is twice the advantage. However, these services have size limits unless you want to pay a fee, plus you are trusting your stuff with someone else.
