Scheduled replication mode is really nothing more than an automatically performed synchronization. The synchronization can be initiated either by a manual activation, or according to a pre-defined schedule, say every few hours or once a day. This replication mode does not differ in principle from a synchronization performed as part of initializing replication. Although there is no online replication in this mode, online changes made during synchronization are replicated.
When the Scheduling option is selected, two options are enabled:
By User Request
Synchronization is activated by a user running synchronization from the Manager, or PowerShell.
In the Weekly Activity setting of the Scheduled mode, servers are synchronized at a scheduled, fixed time. When you select this option, you need to set the schedule for the recurring synchronization.
When selecting a scheduled replication mode it means that synchronization will be performed automatically on a regular basis. Once you select this option the following flexible scheduling capabilities are offered:
Synchronization on selected days of the week and for specific hours in a 24-hour cycle.
Synchronization over selected periods (for example, once every 36 hours) in a 7-day cycle.
Exclusion of specific dates.
To open the schedule
On the Scenario Properties list, open the Replication group. On the Mode property, select the Scheduling value.
The Schedule option appears.
On the Schedule option, select the Weekly Activity value. Then, on the Schedule Settings property, click the Not Set value.
The Schedule Setting dialog appears.
Set the schedule for automatic synchronization according to the guidelines described in the following sections.
The following figure shows a sample scheduling setting in which the solid blue rectangles indicate the days and hours scheduled for synchronization. The excluded dates area lists the specific dates on which synchronization is not performed.
Set a Schedule for Automatic Synchronization
The following instructions describe how to set and clear hours and days in the Schedule Setting dialog for automatic synchronization.
To set a specific hour/day
Select a single rectangle for a specific hour/day. Click the Set button to actually mark and enable that hour/day.
To set a specific hour for each day in the week
Select a column and click the Set button.
To set each hour in a specific day in the week
Select a row and click the Set button.
To set a repetitive cycle
Enter a valid number of hours in the Every box, and click the Apply button.
Note: More than one rectangle can be simultaneously set by clicking and dragging the mouse. You can also use the Ctrl and Shift keys to set several dates at once.
To clear a setting
Use the same technique of selecting, and click the Clear button.
Important! If synchronization is running, and the next scheduled synchronization hour comes up, the new synchronization stops the current one and starts again from the beginning.
Exclude Dates from Scheduled Synchronization
You can set specific dates that will be excluded from the automatic synchronization.
To exclude dates from automatic synchronization
In the Schedule Setting dialog, on the Excluded dates section select or enter the excluded date in the dates box. Then, click the Add button.
The selected date appears in the Excluded dates list.
To remove an excluded date
On the Excluded dates list, select the entry, and click the Remove button. Multiple entries can also be selected by dragging the mouse over them.
