Which is the best backup service for PostgreSQL?

In this blog, we are going to go through the basic steps of using pgBackRest for full and differential backup of PostgreSQL. To read about them more in detail, please visit pgbackrest.org. Here, we are going to build pgBackRest from the source and install it on the host where a test DB cluster is running.

Where to install pgbackrest on a build host?
