This example assumes you back up and replicate only a small number of VMs or evaluate capabilities of Veeam Backup & Replication. For that, you can use a simple deployment scenario: install one instance of Veeam Backup & Replication on a physical or virtual Windows-based machine.
Simple deployment implies that the Veeam backup server fills several roles:
•It functions as a management point, coordinates all jobs, controls their scheduling and performs other administrative activities.
•It acts as the default backup proxy for handling job processing and transferring backup traffic. All services necessary for the backup proxy functionality are installed on the Veeam Backup server locally.
•It is used as the default backup repository.
In a simple deployment scenario all data is handled and stored on the Veeam Backup server locally.
Example 1: All-in-one Physical
In a direct SAN environment, physical hardware with direct FC or iSCSI connectivity is the recommended option for maximum performance.
Example 2: All-in-one Virtual
Virtual hardware, however, can achieve acceptable performance in almost all environments, so this can be the best option in some cases. Installing Veeam Backup & Replication on a virtual machine will enable you to use the Virtual Appliance transport mode, allowing for LAN-free data transfer.
This scenario may be appropriate for development clusters or smaller special-purpose environment within your infrastructure (for example, POC environment).
