This article will help you to configure Esync profile with HO Nas to Branch Nas.


E-Sync is a great tool for doing sync between two storage devices. It operates at the file level, but uses a neat algorithm that detects only the changed parts of files and only sends those changes to the other side.


Requirement for E-Sync

For E-Sync, you require two devices running the NAS OS Professional Version 3.

Both NAS devices should be able to communicate with each other.


If both devices are not in LAN but they are going to connect via WAN, then you should have the static IP of the router of device which you want to take backup. On the router you have to forward following ports to allow communication between two devices

  • TCP Port : 80
  • TCP Port : 443
  • TCP Port : 7887
Please note that all the ports are TCP only.


Once you forward all the ports, just open the user interface of the remote device using static IP, if you get the login screen of the remote device, then every configurations are successful.

For E-Sync to work on the WAN, you should have the active Internet connection on the both devices.


HO Nas IP is 192.168.1.97

Branch IP is  192.168.5.200
