I have been continually frustrated with using Acronis True Image, 9.0 on Windows XP. I created a complete image file of my HD. Then I tried to do incremental backups but the message says that it'll overwrite the file--which is not what I want to do. So then I created a backup using files and folders, which was okay, but then I wanted to do an incremental backup of that and the message says, "the file, XYZ.tib is not a True Image file or is corrupted." Isn't there a difference between an Image file and a Backup file? I never had that problem with Windows System BU. I understand the importance of the Image file so I can totally recreate my system in case of a crash. But how to I do a complete Back Up so I can then do daily incremental backups?
