11. Choose Your Backup Software
When is a backup program not a backup program? A lot of software that calls itself "backup software" does not actually perform backups in the sense we're discussing here. That is to say, some backup programs do not create additive incremental archives, some do not create duplicates, and some do neither!
Unfortunately, because software developers use terms such as "incremental," "archive," and "backup" differently, you may think you're getting certain capabilities when you buy a product that later turn out to be missing. Thus it is extremely important that you read the fine print, and understand exactly what it is you're looking for.
