title: Postgresql: How to take incremental backup with Barman
body: <p>I am new to Postgresql, I've found a tool named Barman for taking incremental backup of database. But the few tutorials aren't helping that much as they're not for naive users. </p>
  
  <p>Can someone help explaining the steps simply how to backup data with Barman? That would be a great help ! I'm using Postgres 10.4 in Ubuntu 18.04.</p>
