When Veeam Enterprise Manager replicates databases from backup servers, it also synchronizes license data: checks if the license installed on the Veeam backup server coincides with the license installed on the Veeam Backup Enterprise Manager server. Veeam Backup Enterprise Manager collects information about the type of license installed on Veeam backup servers connected to it and the number of instances in the license. When you run a job, Veeam Backup & Replication uses a number of instances required for each type of protected workloads (for per-instance licenses) or applies a license to the protected hosts (for per-socket license). The Veeam Backup & Replication infrastructure requires license instances to process backup and replication jobs.
