After defined, schedules can be easily modified to meet the changing requirements of the replication policies. When modifying a schedule, the scheduled date and time, as well as the interval in which the schedule will run, can be changed.
  1. Navigate to Home > Data Protection > File Replication, select a schedule, and click details to display its properties in the Modify Schedule page.
  2. Enter the requested information.
    Note: After a data replication job has begun, additional replications for the same policy cannot be started until the current job has completed. However, it is possible to start multiple concurrent replications, each for its own policy.
    Field/Item Description
    Policy Displays information about the replication policy being scheduled.
    Replication Policy Displays the name of the replication policy being scheduled.
    Next Run Displays the date and time of the next replication run specified by this schedule.
    Last Status Displays the status of the last run of this schedule. Click the View Latest Report to display the replication report for the last replication run according to this schedule.
    Immediate Actions Click Run now to run the replication policy immediately, regardless of schedule.
    Note: A replication job cannot be started if a previous instance of the same policy is still in progress. In this case, the replication is skipped, and an error is logged.

    Click Abort to stop an in-progress replication.

    Recovery Actions Click restart to restart the replication if the previous replication attempt failed.

    Click rollback to roll back a failed or aborted replication. The target file system is rolled back to the last good snapshot. Note that a snapshot is taken after every successful replication.

    Note: Rollback should only be used when the target will be used as the live file system. If the replication's source file system cannot be used as the live file system (either permanently or temporarily), users can access the latest available data on the replication target (the file system created by the last successful replication).

    If the target file system will be used as the live file system permanently, delete the replication policy and all related schedules (since the source will not be used for this replication again). You can then create new replication policies and schedules.

    If the target file system will be used as the live file system temporarily, contact customer support for assistance in synchronizing the "old" (source) and the "new" (target) file systems before transferring access and resuming replication operations as implemented prior to the "rollback."

    Timing This section displays information about the execution timing for the replication policy, and it allows you to reschedule the next (or final) execution of the replication policy.
    Schedule Time Time of the next replication specified by this schedule.
    Schedule Date Date of the next replication specified by this schedule.
    Date of Final Run Date of the final replication specified by this schedule.
    Reschedule This section allows changing the schedule of the next or final replication specified by this schedule:
    • To change the schedule of the next replication, fill the Reschedule box, then enter the new values for the Time and/or Date.
    • To change the schedule of the final replication, fill the Reschedule box, and enter the new value for the Final Run in the appropriate fields.
    Current SMU Date and Time Current date and time as set on the SMU.
    Schedule This section allows you to specify how often the replication policy is to be executed. Select one of the radio buttons:
    • From the list, select daily, monthly, or weekly based on the scheduled date and time.
    • Enter a quantity, and from the list select hours or days based on the scheduled date and time.
    • Enter a quantity to complete the label: Continuous. Pause quantity hours between runs. The new replication job can start immediately or after a specified number of hours.
    • Selecting Once, at the scheduled date and time guarantees that the policy is scheduled to run only once.
    • Selecting Inactive causes the replication schedule to be placed on pause.
    Actions
    OK Saves changes to the replication policy schedule, and returns to the File Replication page.
    cancel Returns to the File Replication page without saving changes to the replication policy schedule.
  3. Verify your settings, and click OK to save, or cancel to decline.
