The Part of Backup Nobody Mentions by Vinny La Bash, Member of the Sarasota Personal Computer Users Group, Inc., Florida

 There are dozens if not hundreds of ways to backup your data, but we're not going to talk about that. We're going to discuss http://www.techsoup.org/the most important part of doing a backup, the part that is hardly ever mentioned. Do you believe that your backup is a sound copy of your data? Would you be at ease if all your files suddenly disappeared from your computer, and all you had was your backup to restore them?

 If your confidence fizzled to zero, what's the problem?

You may have developed the most sophisticated and comprehensive backup scheme the computer world has ever seen, but you won't ever know if it's any good unless you test it. Without a valid method of testing, you can have no confidence in your backups. There are many things that can go wrong with a backup, some beyond your control, some not.

Perhaps one day you were in too much of a hurry, and you made a backup of one folder instead of your entire system as you planned. Hmm, no wonder that backup completed so fast.

Your backup disk got exposed to a magnetic field and scrambled all your data.

The CD containing your data was left in the car, and excessive heat warped the media, making it unreadable.

You encrypted your backup and lost the password to restore it.

You upgraded your backup software, and now it can't read your old backups.

Your new upgraded backup software program becomes corrupted, and you can't make a new backup or restore an old one.

Your new backup program has a great innovative file compression scheme. However, it turns out that it compresses better than anyone expected.

You upgrade your Windows Operating System and your backup software no longer works. (Rare, but it happens).

Let's stop here before you get too depressed to make another backup. What's important is to understand that a great many things can go wrong even with the best backup methods.

The only true test of your backup is to do a restore and see if it works. Does this mean you have to erase all your files, and then run a restore from your backup media? No. Fortunately, there are less chancy ways of verifying your backup data.

 One thing you can do is install a second hard drive and restore your data files to the second disk. If your original disk has enough capacity, you can partition it into at least two sections, and restore into one of the new partitions. Hard drives have become almost dirt cheap, so this is not particularly expensive.

 Another thing you can do is make at least three backups and store them in three different locations for safety. Keep one copy at home, but in a different room than your computer. Store a second copy at your office or a friend's house, and do the same for him or her. The third copy could be in a safe deposit box or similar secure location.

 If you feel that such measures are not necessary, ask yourself if you are ready to perform the ultimate test. Would you feel totally at ease erasing your hard disk today and restoring it from your backups? If not, then think again.
