Overview of this book

PostgreSQL is one of the most powerful and easy to use database management systems. It has strong support from the community and is being actively developed with a new release every year. PostgreSQL supports the most advanced features included in SQL standards. It also provides NoSQL capabilities and very rich data types and extensions. All of this makes PostgreSQL a very attractive solution in software systems. If you run a database, you want it to perform well and you want to be able to secure it.

Now that we have installed and configured Barman it is now time to use Barman for its actual purpose, that is, taking backups with Barman and recovering PostgreSQL using the backups taken with Barman. This section is divided into two areas, first taking the backup and then testing its recovery.

Getting ready

All the steps in this recipe require Barman to be installed on the backup server. For restoring data we are going to use a new server named pg-clone.

How to do it...

The first part is to take backups, which will be done here. The following steps are all carried out on the backup server:

  1. First, we create a Barman backup with the following command:

            barman backup primary 
    
    
  2. In the next step, we examine the list of backups with the following command:

            barman list-backup primary 
    
    
  3. In the third step, we check the metadata of the most recent backup:

            barman show-backup primary latest 
    
    
  4. In the next step, we see all files that were...
