Automatic schedule types include Full, Cumulative Incremental, and Differential Incremental. Client-requested schedules specify when users can start user backups and archives from the clients. This can be further broken into user backup schedule types or user archive schedule types. >>> For schedule methods, there are two: frequency-based and calendar-based. When b-p-sched starts, it searches for schedules, either calendar-based or frequency-based, that have open windows. The b-p-sched utility builds a work list accordingly, consisting of backup jobs that are due to run. Frequency-based schedules typically run every day, every hour, every 4 hours, etc. Calendar-based schedules run specifically on certain days of the week or days of the month. >>> Frequency-based or calendar-based schedules require the backup window to be open for the job to start; however, the backup jobs do not have to complete within the window, they simply have to start within the window.
