Updating Veeam Backup & Replication

Apart from major version releases of Veeam Backup & Replication (for example, 12, 12.1), Veeam Software provides updates (for example, Cumulative Patch P20230223 for v12, update for v12.1). Updates contain bug fixes, performance enhancements and introduce new features.
