The distributed deployment scenario is recommended for large geographically dispersed virtual environments with multiple backup servers installed across different sites. These backup servers are federated under Veeam Backup Enterprise Manager — an optional component that provides centralized management and reporting for these servers through a web interface.
Veeam Backup Enterprise Manager collects data from backup servers and enables you to run backup and replication jobs across the entire backup infrastructure through a single "pane of glass", edit them and clone jobs using a single job as a template. It also provides reporting data for various areas (for example, all jobs performed within the last 24 hours or 7 days, all VMs engaged in these jobs and so on). Using indexing data consolidated on one server, Veeam Backup Enterprise Manager provides advanced capabilities to search for VM guest OS files in VM backups created on all backup servers (even if they are stored on backup repositories on different sites), and recover them in a single click. Search for VM guest OS files is enabled through Veeam Backup Enterprise Manager itself; to streamline the search process, you can optionally deploy a Veeam Backup Search server in your backup infrastructure.
With flexible delegation options and security roles, IT administrators can delegate the necessary file restore or VM restore rights to authorized personnel in the organization – for example, allow database administrators to restore Oracle or SQL server VMs.
If you use Veeam Backup Enterprise Manager in your backup infrastructure, you do not need to install licenses on every backup server you deploy. Instead, you can install one license on the Veeam Backup Enterprise Manager server and it will be applied to all servers across your backup infrastructure. This approach simplifies tracking license usage and license updates across multiple backup servers.
