.. _enable_a_scheduled_data_sync: Enable a Scheduled Data Sync ---------------------------- By default, when a Cisco Unified Communications Manager or Cisco Unity Connection device is set up in VOSS-4-UC, a full data sync instance is created to perform the initial sync of all data from the device. A Change Notification Sync type also gets created in the Data Sync page. In addition, a Schedule is created to execute that data sync every 14 days, but is disabled by default. We recommend running the full data sync manually only when necessary. However, if a regularly scheduled sync is desired, the schedule can be enabled as follows: **Perform these steps**: 1. Log in as provider administrator. #. On the **Scheduling** form (default menu **Administration Tools > Scheduling**) choose the schedule instance that matches this naming convention: HcsSync-<ip_address>-<device_name>-SCHED. For example: HcsSync-192.0.2.24-CUCM01-SCHED #. Select the **Active** check box. #. Click the **Multiple Executions** tab, and update the interval, if desired. #. Click **Save**. The full data sync executes immediately, and executes again according to the schedule.
