Recently several authors I know have lost books, works in progress, and assorted other documents when their computers did a bunk. As Emeril says--Bam! You're down for the count, in complete disarray. There are tons of options to backup your files. I'm not going to get into a discussion of options.
What I want to know is... why would you not back up your docs? Even the most naive individual must suspect that there will eventually be a breakdown in their system. If the documents are important to that individual, then surely they are worth the three minutes it takes to back them up.
However! If the backup isn't in a place other than the computer then if the computer is destroyed due to fire or flood, the backup will most likely also be destroyed. In another life I used to teach computer basics. One of the things we discussed was this issue. Where should you keep your backup?
Number one answer among my students was? Next to the computer.
We played a game of suppose. Suppose your house/apartment burned down while you went to the grocery store. Suppose a tornado whirled in and wiped out your apartment/home. Suppose, suppose, suppose... The truth is that the safest place for your backup is not in your home. The second truth is that you should probably have a minimum of three backups. One on Monday morning, one on Wednesday night, and one on Saturday afternoon. Rotate them. The maximum work lost will be three days.
Too much? Back up everyday rotating three backups such as flash drives or whatever your option of choice is. The important thing is to have multiple backups.
Because backing up means "never having to say you're sorry"!
