Dear Ashanta, Incremental and Differential backups are not the same, though they both require a FULL Backup to start with. For example: December 1st. : FULL backup is performed. December 3rd. : Fife 1 is added. December 5th. : Incremental backup is performed, and it will include the File 1 in the backup. Differential backup is performed, and it will include the File 1 in the backup. December 7th. : Fife 2 is added. December 10th. : Incremental backup is performed, and it will include only the File 2 in the backup. Differential backup is performed, and it will include both the File 1 and File 2 in the backup. Thus, incremental backup only contains what has changed since the last backup whether it is FULL or Incremental backup. Whereas, Differential backup always backup what is changed from only the FULL backup. As far as your environment is concerned with Rollback Rx, you should be only taking a FULL backup once a month, or once every two months. Both Incremental and/or Differential backup in your case will mess up things read bad. I will rely on two imaging programs, one paid but great and cheap and the other one free and great. For paid one, I will rely on IFW: http://www.bitsdujour.com/software/image-for-windows/ BTW, both Brain K and Pandlouk are experts on IFW on this forum. For free one, I will rely on Macrium Reflect: http://www.macrium.com/reflectfree.aspx I paid $100 for Macrium Reflect v4 and within 6 months, they came out with v5 and they wanted $60 more. So, I tried their free version and the main difference is that with paid version they give WinPE and with free version you have to build your own WinPE. For further information on this, see my above post #36. Too expensive, and too limited. Best regards, KOR!
