Hello, I am using the trial version of Acronis True Image 11.0 and have only a couple of days left in the evaluation. I want to backup only Windows and my installed programs, so I made a backup image of my C:\ drive. The physical drive is close to 17Gb with 15.2Gb of data in it. The .tib backup file is just 9.2Gb. I used default options for the backup (no additional compression). I am amazed by the size reduction: 15.2Gb of data fitting inside a 9.2Gb archive ! ! ! Do you think that all my data is here, including all values in the registry setting? How is it achievable to have such a good compression? I am amazed (or missing something).
