When utilizing Always On Availability Groups on a Windows Server Failover Cluster using Microsoft SQL Server 2017 and after installing Cumulative Update package 15 (CU15) for SQL Server 2017, Veeam Transaction Log Backup Jobs may fail with the following error message in the the statistics window for the transaction log backup job:

Configuration data for the availability group with Windows Server Failover Clustering (WSFC) resource ID '' is not found in the WSFC data store. The availability group may have been dropped, or a previous CREATE AVAILABILITY GROUP or DROP AVAILABILITY GROUP operation has failed.
