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.

Info

Configuration files

Below is a description of the properties you need to specify for each section.

proxy connections

Section: connections/node1/proxy, connections/node2/proxy

properties	type	format	description
name	string	name	Connection name. Auto-generated if not specified. Auto-generated format: {resource name}_{relative node name}_{node name}
inside	string	{IP:Port}	Address of the local DRX for the local FSR → local DRX connection
outside	string	{IP:Port}	Address of the local DRX for remote DRX → local DRX connection
hostname	string	host name	Hostname of the machine on which DRX is operating Operates according to the hostname specification in the system configuration.
options	Object	Proxy option	option

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

node1 connection

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

node2 connection

Info
`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.

properties		type	format	description
memlimit		string	{number}{unit}	TX BAB size. default: 1M
bwlimit		string	{number}{unit}	Limit transfers per second
plugin		Object		Plugin settings list
	svc_autostart	string Boolean	true, yes, on,1 false, no, off, 0	Auto-start resources on DRX startup. default: true
	rx_memlimit	string	{number}{unit}	RX BAB size. default: 0
	crypto	string	plugin name	Encryption plugins support: openssl AES256
	compressor	string	plugin name	compression plugin support: zlib, lz4
	compressor_level	string number	1~9	compression level default: 1
