Specification

Recommendation

SQL Database

It is recommended to use an SQL database installed on a dedicated server.

The following versions of PostgreSQL are supported:

  • PostgreSQL 14.x
  • PostgreSQL 15.x (PostgreSQL 15.1 is included in the Veeam Backup & Replication 12 setup, PostgreSQL 15.5 is included in the Veeam Backup & Replication 12.1 setup, but we strongly recommend to download and install the latest PostgreSQL 15.x version)
