This article provides step-by-step instructions for installing and configuring PgBouncer for use with Veeam Backup for Microsoft 365. PgBouncer is a lightweight connection pooler for PostgreSQL, and this guide is intended to help users integrate it with Veeam Backup for Microsoft 365 environments to improve database connection efficiency and performance.
Why should you deploy PgBouncer? Each proxy and repository must connect to the PostgreSQL database when using Veeam Backup for Microsoft 365. This can quickly create thousands of separate database connections in larger environments, overloading the PostgreSQL server’s resources and network, causing performance issues. PgBouncer helps by pooling those connections. Instead of every proxy making its own connection, PgBouncer groups them and reuses connections efficiently. This dramatically reduces the total number of database connections and lowers the strain on the PostgreSQL server, making the system more stable and reliable.
Follow the steps below to install PgBouncer, configure it for use with PostgreSQL, and integrate it with Veeam Backup for Microsoft 365.
