Incremental backup became full backup
Hi,
I am using Acronis True Image 2014 Premium.
Recently I encountered a strange problem:
I have a backup task which uses full backup for the first time backup, and incremental backup in the following backups.
1. When I try to perform that backup task, True Image try to read the drive, but finally reports "Error occured while opening the file.". But I can confirm the drive is readable and all the old backup files exist on the drive correctly.
2. Since I cannot perform the backup task, I have to clone the settings of the backup task and create a new backup task, and then modify the new backup task output directory to another directory on the same drive. Then I start the new backup task. This time the new backup task is started and completed successfully. And produce a full backup of the drive.
However, the problem is on the second day, when I try to perform the new backup task again, I expect True Image will perform an incremental backup, but it actually produces another full backup again.
It seems that for both 1 and 2, True Image has some problems to read the files on the backup drive. But I can confirm the files under the backup drive are readable and I can open and restore them properly without any problems.
Why?
Thanks

Hi,
Thank you. I just figure out the trick. I used to mount a old backup from another old drive. Thus True Image cannot recognized any of my backups on the new drive.
I fix the problem by trying to mount a backup on the new drive, then unmount it. Then perform a backup again, this time True Image is able to recognize all the backups on my new drive.
Very strange but this method works.
