Tasks need interaction
This window accumulates all the tasks that require user interaction in one place. It enables you to specify your decision, such as to confirm reboot or to retry after freeing-up the disk space, on each of the tasks. Until at least one task requires interaction, you can open this window at any time from the managed machine’s Dashboard.
If you select the check box for the Do not show this window when tasks require interaction. I will see this information in the tasks’ details and dashboard. parameter, the tasks will be displayed on the Dashboard among other alerts and warnings.
Alternatively, you can review the task execution states in the Backup plans and tasks view and specify your decision on each task in the Information panel (or in the Task details window).
