Veeam Backup for Microsoft 365 PostgreSQL Database Server

A PostgreSQL instance hosts a centralized configuration database that is used by Veeam Backup for Microsoft 365 components, including backup proxy servers. Data is saved to the file with the VeeamBackup365 name located by default in the C:\Program Files\PostgreSQL\15\data folder on a machine with the PostgreSQL instance.

The basic setup is installing the PostgreSQL Database service alongside with the Veeam Backup for Microsoft 365 Server services, but it might be required to deploy it in an advanced way for larger environments. For advice on deciding for a dedicated PostgreSQL Database Server, please see the sizing page.

If you deploy a dedicated PostgreSQL server for hosting the cosniguration database, please take the instance configuration into account as documented within the Help Center.

For environments where the dedicated PostgreSQL server is experiencing a heavy load, PGbouncer is recommended. PGbouncer is a lightweight connection pooler for PostgreSQL that utilizes asynchronous I/O. It uses Postgres connections only when needed–that is, when inside an open transaction or when a query is active.
