Active Protection, and Windows Encrypted File System
On Dec 1, 2017 I updated my computers to True Image 2018 (I have three computers running Windows 10 Pro).
I use the Windows Encrypted File System (EFS) to encrypt folders on each computer. The encrypted folders are all shared through my HomeGroup. Shortly after updating to TI 2018 I noticed that I cannot share files in the encrypted folders. This manifested itself when software that I use to synch files between the computers abruptly stopped working for the encrypted folders. After spending much time trying to debug the synching software, I discovered that the root problem is that I cannot share any files among the encrypted folders even using Windows File Explorer. In other words, the Windows facility for sharing among these folders is broken.
TI 2018 is the only common change I made to the all of the computers at the time the problem started. So, I tried disabling Active Protection in TI 2018. It did not help. Then I discovered several things. A process called Acronis Active Protection Services is started by Acronis every time the computer boots up, even if the option for active protection is disabled. If you use Task Manager to End Task for Acronis Active Protection Services, a window pops up saying that Active Protection has been terminated and will be autostarted. Then usually after some variable delay, Acronis Active Protection Services is restarted. This behavior occurs no matter whether the option for Active Protection is enabled or disabled. There are no configurations, e.g. one computer enabled and others disabled, that allow sharing among the encrypted folders.
Has this been reported before and is there any explanation or fix? In order to experience this you must have Windows 10 Pro, encrypt folders with EFS, and also share those folders among two or more computers. It's probably not a common configuration.
Thanks
