Active Protection blocks legitimate applications
Operations with Acronis backups
If you attempt to move, rename, delete or modify Acronis backup files in Windows Explorer, Active Protection asks whether you want to allow the Explorer to perform operations with backup files for one hour. Click the button Allow for one hour for that.
If you click Ignore or do not click anything, by default any operations with Acronis backups outside of Acronis software user interface are blocked.
An application was blocked from modifying Acronis True Image settings
If Active Protection reports that an attempt to modify Acronis True Image files or settings was blocked, and you trust the corresponding application, usually you do not have to do anything and just ignore that message.
However, if you absolutely need allow modifying Acronis True Image registry and configuration files outside of Acronis user interface, you can disable the self-defence feature of Active Protection.
Whitelist the executable
If you know what executable file was blocked by Acronis Active Protection, you can add it to the trusted list.
