In a simple deployment scenario, one instance of Veeam Backup & Replication is installed on a physical or virtual Windows-based machine. This installation is referred to as a backup server.
Simple deployment implies that the backup server performs the following:
- It functions as a management point, coordinates all jobs, controls their scheduling and performs other administrative activities.
- It is used as the default backup repository. During installation, Veeam Backup & Replication checks volumes of the machine on which you install the product and identifies a volume with the greatest amount of free disk space. On this volume, Veeam Backup & Replication creates the Backup folder that is used as the default backup repository.
- It is used as a mount server and guest interaction proxy.
In this scenario, source Hyper-V servers act as backup proxies, handling job processing and transferring backup traffic directly to the target. All necessary backup proxy services are installed on source Hyper-V servers.
If you plan to back up and replicate only a small number of VMs or evaluate Veeam Backup & Replication, this configuration is enough to get you started. Veeam Backup & Replication is ready for use right out of the box — as soon as it is installed, you can start using the solution to perform backup and replication operations. To balance the load of backing up and replicating your VMs, you can schedule jobs at different times.
If you decide to use a simple deployment scenario, you can install Veeam Backup & Replication right on the Hyper-V host where VMs you want to work with reside. However, to use this Hyper-V host as the source for backup and replication, you will still need to add it to the Veeam Backup & Replication console. For more information, see Adding Hyper-V Servers.
In Hyper-V environments that require a large number of backup or replication activities performed, the simple deployment scheme is not appropriate due to the following reasons:
- The backup server might not have enough disk capacity to store the required amount of backup data.
- A significant load is placed on production servers that combine the roles of backup proxies and source hosts.
To take the overhead off the backup server and source Hyper-V servers, you can use the advanced deployment scenario. For details, see Advanced Deployment.
