Macrium Reflect Issue RE: Corrupt Incremental or Differential Image Files on
Macrium Reflect v7.1.3147, v7.1.3159 and v7.1.3169


Macrium Reflect has sent me an email of a problem they have discovered concerning Macrium Reflect v7.1.3147, v7.1.3159 and v7.1.3169 for Corrupt Incremental or Differential Image File integrity. Please read quoted text below.

3rd May 2018 - Macrium Reflect Release v7.1.3196

Unfortunately we have just become aware that since release v7.1.3147 on 17th April 2018 it was possible that Macrium Reflect could create corrupt and irreparable Incremental or Differential Image files. The problem occurs if the Macrium Changed Block Tracker (CBT) driver participates in the backup. By default, the CBT driver will participate in the second and subsequent Incremental Image of a backup set after a system reboot. For Differential Images, CBT will participate if the Full Image, in the same backup set, was created in the same Windows session, i.e, no Windows restarts between the Full & Diff. If an image is affected then it is unlikely that it can be mounted and browsed successfully and restore will result in a corrupt file system.

Technically, the problem arose from a misaligned data structure in the code and our testing prior to release didn't trigger this error. We have since introduced more stringent tests that will prevent this type of error from occurring in the future.

Please be assured that integrity of your backups is our top priority. We sincerely and unreservedly apologise for this problem and have worked hard to repair this issue in the latest release.

Macrium support strongly advises that you update to the latest release (v7.1.3196) by taking the 'Other Tasks' > 'Check for updates' menu option.
