The simple deployment scenario is good for small virtual environments or the purpose of the Veeam Backup & Replication evaluation. In this scenario, Veeam Backup & Replication is installed on a single Windows-based machine.
You must not install Veeam Backup & Replication directly on a Hyper-V host. Such installation may lead to unpredictable system behavior. Instead, install Veeam Backup & Replication and its components on dedicated machines. Backup infrastructure component roles can be co-installed..
The machine where Veeam Backup & Replication is installed performs the following roles:
- Backup server that coordinates all jobs, controls their scheduling and performs other administrative activities.
- Default backup repository where backup files are stored. 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.
- Mount server that is needed for restoring of VM guest OS files.
- Guest interaction proxy that is needed for application-aware processing, guest file system indexing and transaction log processing.
The role of the default backup proxy is assigned to the source Hyper-V server. It handles job processing and transfers backup traffic directly to the target server. All services necessary for the backup proxy are installed directly on the source Hyper-V server.
Veeam Backup & Replication is ready for use right after the installation. The only thing you must do is add Microsoft Hyper-V servers that you plan to use as source and target for backup, replication and other activities. For details, see Adding Microsoft Hyper-V Servers.
In Hyper-V environments that require a large number of backup or replication activities to be performed, the simple deployment scheme is not appropriate due to the following reasons:
- The backup server may 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.
