There used to be a single test to determine the effectiveness of your data backup strategy. It centered around successfully restoring your data from a backup, and you would rest easy knowing that you would, in theory, recover from a data loss event. It was really that simple. Still, there were some security concerns as you did not want just anyone accessing the backups who might accidently (or inadvertently) delete them. There was also the threat of confiscating a backup tape containing sensitive or valuable data by an imposter. For the most part, the data backup system was out of sight and out of mind for everyone other than the backup administrator.
