 The **DatamgrService** provides the following synchronization types:
 
 
-- Manual synchronization: The application calls **sync()** to trigger a synchronization. The list of devices to be synchronized and the synchronization mode must be specified. The synchronization mode can be **PULL_ONLY** (pulling remote data to the local end), **PUSH_ONLY** (pushing local data to the remote end), or **PUSH_PULL** (pushing local data to the remote end and pulling remote data to the local end). You can use the [**sync()** with the **query** parameter](../reference/apis/js-apis-distributedKVStore.md#sync-1) to synchronize the data that meets the specified conditions. The manual synchronization is available only for system applications.
