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
 I was using Norton Ghost® previously, but it doesn’t come close providing the value and ease of use I have found with Acronis True Image Deluxe. Thanks for a great product!
