Simply Safe Backup - Backup estimationThe Simply Safe Backup application includes this Backup Job Estimation Tool. The page lists the number of files that will be backed up, as well as the amount of required disk space and media.
I found this estimation tool a particularly nice addition (especially in a free application), as it helps ensure you're prepared for the backup before it runs. In other words, the estimation feature helps eliminate surprises (which are not what you want when working with backups).
