Differential backupDifferential backup allows users to copy files created or changed since the last full or incremental backup. It does not mark files as having been backed up. If you are performing a combination of full and differential backups, restoration of files and folders requires that you have the last full as well as the last differential backup.
Testimonials and User Comments
 Due to the nature of our business, we must upgrade hard drives to accommodate our product line. In the past we had to rely on Norton Ghost® to move our system drives over, keeping our fingers crossed. Finally there's a product that is fast, easy, and reliable with no special booting requirements. Hats off to Acronis for a wonderful product. Thanks guys!
