Barman allows you to implement disaster recovery solutions for databases with high
requirements of business continuity.
Traditionally, Barman has always operated remotely via SSH, taking advantage of rsync
for physical backup operations.
Version 2.0 introduces native support for Streaming Replication backup operations, via pg_basebackup
.
Choosing one of these two methods is a decision you will need to make. The official documentation
deeply describes how to implement it and covers a lot of important general considerations.
In this post, we’ll briefly see how to setup a dedicated Barman server to backup an Advanced Server 3-nodes cluster,
using the SSH method.
