Failed to create a restore point: PostgreSQL database operation failed multiple times with transient error.

To resolve this issue, temporarily increase the timeout to allow the queries to run, then revert the timeout change.

1. Ensure at least Veeam Backup for Microsoft 365 8.3.0.2201 is installed.
2. On the machine where Veeam Backup for Microsoft 365 is installed, stop the following services:
   • Veeam Backup for Microsoft 365 Service
   • Veeam Backup for Microsoft 365 Proxy Service
3. On that machine, open the following configuration file:
   C:\ProgramData\Veeam\Backup365\Config.xml
4. Within the Config.xml file, under the "Veeam/Archiver/RemoteProxyDeploymentSettings" node, identify the following settings and note their existing values. Each setting and value will be listed twice in that line. Once noted, so you can revert the value later, update the values as shown below:
   • command timeout=600
   • timeout=600
5. Start the Veeam Backup for Microsoft 365 Service service.
6. Open the Veeam Backup for Microsoft 365 Console, and use the Upgrade function on each proxy used by the job that was failing to push the updated timeout values.
7. Run the job that failed, and once it succeeds, revert the timeout changes:
   1. Ensure all jobs are stopped.
   2. Stop the Veeam Backup for Microsoft 365 Service and Veeam Backup for Microsoft 365 Proxy Service services.
   3. Modify the Config.xml file and replace the updated timeout values with the original ones (default is 60).
   4. Start the Veeam Backup for Microsoft 365 Service service.
   5. Upgrade the Proxies again to push out the updated timeout values.
