"Backup!" It was my first day of class, as a new instructor, in front of a full classroom of anxious bodies waiting to start their career in data processing. As usually is the case, when I entered the classroom, everyone stopped talking and tuned their attention to me. I didn't mutter a word, but went right to the blackboard and wrote my name big enough for everyone to see. As I completed writing my name, I turned around and shouted abruptly, "BACKUP!"

Believe me, I HAD their attention! I proceeded to instruct them that if there could be one lesson that these students of mine would learn from me, it would be BACKING UP! Backing up what, you ask? Their computer's hard drive, that's what. Their blood, sweat, and tears that they pour into their work. It's worth the time to create, so it should also be worth the short time it takes to back it up. BACKUP (defined) - a. Simply copying files from the computers hard disk drive to another removable storage medium's device; i.e. namely diskettes, or tapes, zip drives, thumb/flash/memory or optical drives, CD’s, or DVD’s, etc. b. saving one's own work as a secondary copy of the original. Should the original become corrupted, totally destroyed or just lost, the BACKUP can then be copied over the original, making it new again, or at least as current as the last time you made a BACKUP copy of it! RESTORE (defined) - a. the process of copying a "BACKUP copy" of a file, over an "original copy" of the same file, in order to bring it up-to-date. A backup restores the original back to the way it was to begin with. If a file becomes corrupted destroyed or lost, the BACKUP copy can RESTORE the original, as it was last copied, prior to the mishap. Cheap insurance is what I call it! For the price a tape, CD, or DVD drive (or whatever type of backup device your application requires) and 3 tapes/CDs/DVDs (a minimum required for rotation of the backups; i.e. call one tape/CD/DVD the grandparent, another the parent, and the third call the child copy using the grandparent copy on Monday, and the parent copy on Tuesday, etc. rotating them regularly), you never have to worry about losing any significant amount of your blood, sweat, and hard work ever again! The tears would come if you worked long and hard on a document, lost it and didn't have a backup copy! Been there, experienced that. Tape Backup devices are worth their weight in gold! I know that may sound a bit eccentric. But, if you compiled a lot of information, only to lose it after the time, effort, etc. that went into it, I know you would feel that the cost of a tape backup device and 3 tapes, would be insignificant compared to what it would cost in time, effort, etc. to redo it, if that is even possible. Just having the personal assurance that comes with a backup device, will keep you from jumping off high buildings or taking more aspirin than a human should! Worry not, with a BACKUP! Nevertheless, as an extra point question on the final exam, I asked my students, "Which ONE lesson do I want all of you to learn from me and practice regularly on your computers or at your jobs? Every student in that class got the extra point! So, THE MORAL OF THIS STORY IS… Backup often, you'll be glad you did! This article was written by Tim Gettig.
