Setting a Maintenance Window

Usage Notes

• You can only set a maintenance window for restarting an instance, changing instance specifications, or patching an instance.
• Specification changes or patching must wait for the maintenance window, but instances can restart immediately.
• You can cancel a scheduled task.
• Changing the maintenance window does not affect tasks that have been scheduled.
• If the maintenance window and backup time are the same, scheduled tasks may fail.
• In the maintenance window, scheduled tasks are scanned every 10 minutes. If a task is delivered when the maintenance period is about to end, it may fail to be scanned and will be canceled.
