On an Dell Avamar server, the maintenance schedule is enabled. If the server is over a certain capacity, when will the server automatically cancel backups that are running under the default configuration?

The Avamar maintenance window is a dedicated period for essential server tasks like garbage collection, checkpoints, and HFS checks. To ensure these critical processes have the necessary system resources and to maintain data consistency, Avamar is designed to automatically cancel any backups that are still running when this window begins. The blackout window, which precedes the maintenance window, only prevents new backups from starting; it does not affect currently running jobs. This cancellation mechanism is crucial for the health and performance of the Avamar grid.

A. The blackout window's purpose is to prevent new backups from starting, not to cancel jobs that are already in progress.
C. Checkpoints occur during the maintenance window, not the blackout window. Cancellation happens at the start of the maintenance window itself.
D. This is the opposite of the question's premise. The server cancels the backup precisely because it has not completed by the time maintenance must start.

If backups are still running when the maintenance window begins, the server cancels the backups so that maintenance can start."
