Starting from Veeam Backup & Replication v12, the PostgreSQL database can be used instead of Microsoft SQL Server. It will interest you to know that, this default installation comes with PostgreSQL. PostgreSQL runs on all major operating systems, including Linux, UNIX (AIX, BSD, HP-UX, macOS, Solaris), and Windows. In this article, you will learn how to Install PostgreSQL on a Windows server as a Veeam Database Engine. Please see How to install PostgreSQL on Ubuntu, How to install Mattermost on Ubuntu and Debian, and how to upgrade Veeam Backup and Replication v11 to v12.1.
PostgreSQL is a powerful, open-source object-relational database system with active development that has earned it a strong reputation for reliability, feature robustness, and performance. Since it is an object-oriented database that is fully ACID-compliant and highly extensible. It enables the community to add new features and capabilities as workload demands evolve.
This choice allows Veeam to leverage a powerful and proven database solution for managing its backup and recovery data.

Why did Veeam Switch to Postgre as the Default Database Engine?
This decision to switch to PostgreSQL was made due to the limitation associated with Microsft SQL Express edition in terms of scaling (eg max 10 GB Database size). See the System requirements
PostgreSQL does not have these limitations and it does not require an expensive license either. Additionally, the default installation will automatically tune the database for Veeam Backup & Replication.
