Acronis activitiers in the background

Hello,

regulary I can see in the task bar that Acronis Trueimage is doing tasks in the backround I can see something like "Acronis True Image 50% done "My volumes".
I see the white arrow at blue backround at the task bar. But I did not configured anything and I do not want that Acronis is doing anything. No SYNC or BACKUP or anything else.

But in the configuration I can not see anything is running.
How can I find out what Acronis is doing and how can I disable it.

I just want do do a backup when ever I want it to do and when Acronis would like.

Andreas
