SmartSync is a backup option inside NAS-7410, and its main use is for Remote Data Synchronization. It is used when there is NAS-7410 set up on both local and remote areas. We create a synchronous connection of data stream between the matching volumes and folders on the two servers, enabling the synchronization of data on both sides. The benefit is that SmartSync allows the remote backup of large amount of data stored on NAS-7410 servers, ensuring the security of the data.
