According to the Veeam Backup & Replication Best Practice Guide1, some of the reasons why it is recommended to have a Veeam backup server at each of the three sites are:

•Each site has production data. This reason is based on the principle of locality, which states that backup data should be stored as close as possible to the source data, to reduce network traffic and latency, and to improve backup and restore speed and efficiency. Having a Veeam backup server at each site allows you to perform local backups of the production data at each site, without having tocross the WAN or VPN connections between sites.
