The Image backup job will fail with the error message "Source might be altered. Please check if the source disk order is correct". This error may occur when the GUID of a volume has been changed after configuring the disk image backup.


The GUID of a volume could be changed due to the following scenarios if:

1.The configured volume has been extended or shrunk. 2. The volume letter has been changed for the configured volumes. 3. The disk order has been changed after configuring the backup job.

After checking the above steps, run an additional full backup to overcome this issue.
