LSync is a tool for scripted synchronization and backups. It provides a custom Ruby DSL for describing complex backup and synchronization tasks. It is designed to give maximum flexibility while reducing the complexity of describing complex multi-server setups. For examples please see the main project page.
- Single and multi-server data synchronization.
- Incremental backups both locally and remotely.
- Backup staging and coordination.
- Backup verification using
- Data backup redundancy controlled via DNS.
Add this line to your application's Gemfile:
And then execute:
Or install it yourself as:
$ gem install lsync
LSync imposes a particular structure regarding the organisation of backup scripts: Backup scripts involve a set of servers and directories. A server is a logical unit where files are available or stored. Directories are specific places within servers.
A simple backup script might look something like this:
#!/usr/bin/env ruby require 'lsync' require 'lsync/shells/ssh' require 'lsync/methods/rsync' :: do |script| script.method = ::::.(:push, :arguments => ["--archive", "--delete"]) # Set :src to be the master server script.master = :src server(:src) do |server| server.host = "server.example.com" server.root = "/" end server(:dst) do |server| server.host = "backup.example.com" server.root = "/" end backup('etc', 'var', 'srv', 'home') end
