Challenge
A backup job that targets a cloud repository, that is hosted by a service provider whose Cloud Connect server utilizes PostgreSQL for storing the configuration database, fails with the error:
Inner SQL exception in the service provider infrastructure. Please contact your service provider.
This error may also occur when backing up to a non-cloud repository if the Veeam Backup & Replication deployment uses PostgreSQL 15.1 or 15.2 to host its configuration database.
Cause
If the Service Provider's Cloud Connect server uses PostgresSQL for its configuration database, the Service Provider should check logs to verify if this article is relevant.
Default path: C:\ProgramData\Veeam\Backup\CloudConnectService\<tenant_name>\<job_name>\Session.log
Example of error in Session.log on the Service Provider side:
Solution
To resolve and prevent this issue, Veeam recommends all customers (including Servicer Providers) with Veeam Backup & Replication or Veeam Cloud Connect deployments using PostgreSQL 15.1 or 15.2 upgrade to the latest 15.x version of PostgreSQL.
A guide on how to upgrade the backend PostgreSQL database engine is available on Veeam KB 4386.
