SEP sesam schedules represent a framework for automating task execution. Different events, such as backup, migration, replication, restore, etc., can be linked to a schedule and configured to occur at a specified time.
A schedule defines the recurrence of an event and may be executed in minutes, hours, days, months or years. It can be set up to start periodically or to be executed only once. A schedule can be used for any number of events and the events of a particular task (backup, restore, migration, etc.) can be configured in several schedules. All schedules and related jobs are configured and run in the SEP sesam Server's time zone.
Schedules always contain one predefined task: a NEWDAY schedule that is linked to a NEWDAY event. SEP sesam uses the NEWDAY event to reorder its database, enable uninterrupted activity of the SEP sesam processes and to define a new backup day. Do not deactivate a NEWDAY event or delete a NEWDAY schedule, because this will cause SEP sesam to stop working properly! For details, see NEWDAY event.
To create a schedule, proceed as follows:
- From Main Selection -> Scheduling -> Schedules, click New schedule. The Schedule window appears.
- By default, Execution is already enabled. Use this option to activate or disable the schedule. If you deselect the execution option (No), the schedule will still be displayed as shaded in the list of schedules but all events linked to this schedule will be deactivated.
- In the Name field, enter the name for the schedule.
- The Cycle table provides a selection of different time parameters to configure the time intervals for scheduled jobs. Jobs can occur once or recur daily, weekly, monthly, or yearly. For example, you can schedule a full backup to take place every Friday at 18:00. From the tabs on the left, select one of the following:
- once – no repetition, single run
- daily – repetition in days, hours or minutes
- weekly – repetition in weeks or weekdays
- monthly – repetition on absolute or relative dates: 1st/2nd... or Mon/Tue...
- yearly – repetition on absolute or relative dates
- Under the Period of validity, specify the time range for the schedule. Click the arrows in the date field to display a calendar.
By default, the current date is already entered in the Begin field. You can specify any date as a start time for your periodical event. The schedule will only be activated after the specified date and there can be no execution prior to this date. If you want your schedule to be valid for a limited period of time only, e.g., half a year, select the End check box and enter the date of its suspension. By default, this option is disabled and the schedule will be repeated in perpetuity.
- Under the Start time frame, select the start time for your schedule – all events related to this schedule will be started at the time defined by this parameter. Keep in mind that the actual start time depends on the processor load of the system. At the starting time of the event, every event is forwarded to the queue, where it may have to wait until jobs with higher priorities are completed. For jobs with the same priority, the FIFO rule (first in, first out) applies. You can also limit the start time by specifying the Duration. This option specifies the amount of time in days and/or hours for which an event can be in the queue. If the event cannot be executed within the duration time frame, it will not be executed at all.
- Click OK to save the schedule.
