Acronis backup 11.7, "Need Interaction" ,
I have a VM backup execution state 95% "need interaction", unfortunately can not stop this task,
welcome to Acronis forums! Have you checked the operation log of this backup task (backup storage might be unavailable or full)? The log may give more details on what interaction is needed from the user.
If you can't stop the task from Acronis Management Server, try to connect to the machine with Agent directly and cancel the task directly on the Agent via Task Manager.
