A trick often used by administrators is to allow for time buffers before starting the next job. The buffer times are necessary because it is not possible to predict exactly how long a job will take to complete, since the duration depends on many incalculable parameters. Since it makes little sense to run backups and SAP jobs at the same time, these tasks are usually done one after the other rather than in parallel. In more complex environments, data backup durations, time buffers and job runtimes add up to such an extent that the time available is no longer sufficient to perform all activities within the available time corridor. Tools that work with status dependencies and then automatically start the next job when its predecessor job has been processed without errors can help here.
