Configuring file replication

2023/02/10

 

This section describes how to work with the File Replication FSR.

Overview

Unlike BSR, FSR connections are 1-channel connections that handle both replication and meta-packets. If you look at the drx connection information, you will see that it is marked as a complex type.

Proxy option

option

The FSR connects to the inside address and the remote DRX connects to the outside address.

  • node1 connection

Local FSR Local DRX Remote DRX (node1 url) <-> (node1/proxy/inside | node1/proxy/outside) <-> (node2/proxy/outside)

  • node2 connection

Remote DRX Local DRX Local FSR (node1/proxy/outside) <-> (node2/proxy/outside | node2/proxy/inside) <-> (node2 url)

 

proxy options

  • section: proxy, connections/node1/proxy/options, connections/node2/proxy/options

Each option can be overridden hierarchically lower down the hierarchy.
