FAQs

SmartSync currently supports data synchronization only from NAS-7410 to other NAS-7410 servers. We may consider implementing data synchronization from Windows platform to NAS-7410 at the second stage.

Each NAS-7410 can perform 8 tasks simultaneously, including immediate and scheduled ones. However, we do not recommend running too many tasks at the same time, since running more tasks means more system resources are required as well as the network bandwidth. This will greatly affect the performance of NAS-7410 and the network.

Please check the following:

1. The PC installed Bonjour Browser is not in the same LAN as IHD-410PT or IHD-410PR.
   
2. The IP address of PC might be in a different subnet from IHD-410PT/IHD-410PR. Please set the PC’s IP address in the same subnet as IHD-410PT/IHD-410PR.

1. The IHD-410PT has a different firmware from the IHD-410PR, so please choose the correct firmware before upgrading the firmware.
   
2. Do not interrupt the upgrading procedure.

Because SmartSync is a memory-consuming operation, memory utilization rate is critical when launching this task. When NAS-7410 detects the free memory is low, the program will terminate the synchronization task. To avoid this situation, we suggest checking the following configurations or timing before launching SmartSync task.
1. Set the SmartSync task to perform at non-rush hour to avoid memory conflict with routine network services.
2. Set a proper SmartSync source path. If the SmartSync source includes up to millions files/directories, that will occupy most of the memory capacity when creating check list, it is suggested assigning the source path in multiple sub-directory in different tasks.

If we do not control the bandwidth for the data stream when SmartSync is performing its tasks, the synchronous connection may occupy a lion share of the whole network bandwidth, making the server or network unable to provide other services to the clients at a good performance, especially those at the remote network area. Although most enterprises are now using broadband connections, they normally provide various services using these connections. To prevent SmartSync from occupying too much of the network bandwidth, it is recommended to set up Bandwidth Control during execution of the tasks. Some parameters to be considered are: 1. the total bandwidth and the distribution of bandwidth that the enterprise has in its network environment; 2. the frequency of accesses by the clients and the number of clients served by NAS-7410.

SmartSync does not use CIFS/SMB, FTP or NFS as its communication protocol. It is based on SSL over TCP/IP. This also means SmartSync has its own security policy and won't refer to SMB, FTP or NFS security setting.
