Running a Veeam Endpoint Backup (VEP) of Veeam Agent for Windows (VAW) backup job to a repository in Veeam Backup & Replication returns the following error:
Veeam Backup & Replication is providing an incorrect repository ID due to VEP/VAW backups being imported in.
Check the Veeam Backup & Replication GUI under 'Backup & Replication' view, and verify if the backup job shows under disk imported. If it does, remove the backups from configuration. Then re-run VEP/VAW backup to check how it works.
