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, which 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.
SEP sesam provides flexible scheduling features to customize how and when your events are processed. By using the User defined option, you can create a calendar that is customized according to your country- or company-specific requirements. For details, see Creating a Custom Calendar.
To create a schedule, proceed as follows:
- From Main Selection -> Scheduling -> Schedules, click New schedule. The New Schedule window appears.
- In the Name field, enter the name for the schedule.
- By default, the Execution is already enabled. Use this option to disable the schedule. If you select the Execution off option (previously deselect the Execution option), all events that are linked to this schedule will be deactivated. The schedule will still be displayed as shaded in the list of schedules, but the related jobs will not run. You can deactivate a schedule if you want to exclude scheduled jobs to run on specific days, such as holidays. For more details, see Creating a Custom Calendar.
- Specify the time range and start time for the schedule in the Start field. Click the arrows in the date field to display a calendar. By default, the current date is already entered. In the next field, specify the start time, e.g., 18.30. 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.
- If you want your schedule to be valid for a limited period of time only, e.g., until the end of the year, check the Expiration date option and enter the date of its suspension. The schedule will be deleted after the Expiration date criterion is met. By default, this option is disabled and the schedule will be repeated in perpetuity.
- The 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. You can also use User defined option to create a custom calendar that is customized according to your needs.
For example, you can schedule a full backup to take place every Friday at 20:00. From the tabs on the left, select one of the following:
- Once – no repetition, single run (After execution the schedule is deleted!)
- 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
- User Defined – option for setting up a custom calendar, see Creating a Custom Calendar.
- Under Advanced settings you can further refine your schedule.
- Optionally, select the Start time frame check box if you want to define the maximum allowed startup time for your event. Specify the startup time in days and/or hours. If the event cannot be executed within this specified time frame, it will not be executed at all. If this option is not enabled, the allowed start time of the task is not limited and a job can be started at any time when the resource is available.
- You can also specify a time frame for repeating the event. Select the Repeat task check box and choose how often (in hours and minutes) the task should be repeated. Use the For a duration of field if you want to specify the duration of the repeated event (days and/or hours).
- Optionally, you can specify the time frame after which the scheduled event will be cancelled by selecting the Stop task if runs longer than check box and specifying the amount of time (in days and/or hours) following the event's scheduled start time after which the event will be cancelled.
- Click OK to save the schedule.
