LAN Sync refers to a file synchronization approach that accelerates the sync process when a shared file or folder already exists on a Local Area Network (LAN).

Typically, under a standard sync method, when a shared file is created, each subscribed device begins an individual sync process with the AXIS Cloud Sync Server.

 

With LAN Sync, when a new shared file is created, one agent will synchronize with the AXIS Cloud Sync server, and all other agents will synchronize from one another within the LAN. LAN Sync is a faster and more efficient process, and is particularly useful in environments with limited bandwidth.

 

Note: LAN Sync requires that agents are connected to the AXIS Cloud Sync server; LAN Sync is not intended to support off-line mode.

End users can turn on the LAN Sync option from the agent Properties dialog box on their local machines. These end users must also be connected to the AXIS Cloud Sync server and operate within a Local Area Network.

LAN Sync Scenarios

It is important to note that because an agent’s file only represents its latest version, the LAN Sync process will take effect when a new shared file is created within a LAN. More specifically, LAN Sync will take effect during the following scenarios:

A new file is created within the LAN:
  1. An agent will synchronize with the AXIS Cloud Sync server.
  2. Agents that need the file will synchronize from other agents within the LAN. 
A new file is created outside of the LAN:
  1. An agent will synchronize with the AXIS Cloud Sync server.
  2. The new file will be distributed across the LAN. In some instances, the agent that synchronized with the AXIS Cloud Sync server will distribute the file, and in other instances, multiple agents will help with the distribution process. The exact process is determined by the load balancer.
A new agent joins the LAN:
  1. The new agent will synchronize files from other agents within the LAN.

Technical Details

LAN Sync agents communicate with one another through TCP and UDP ports. The TCP port is responsible for reliable data transfer, and is encrypted.

How To Turn On LAN Sync

To turn on LAN Sync on a Windows or Mac Machine:

  1. In the system tray, click the AXIS Cloud Sync Tool icon and select Properties. The Properties dialog box displays.
  2. Click the Bandwidth tab.
  3. In the Bandwidth tab, click the Enable LAN Sync checkbox. By default, checkbox is unchecked.

    LAN Sync is now enabled for the agent.
