To work with HPE StoreOnce, Veeam Backup & Replication leverages the HPE StoreOnce Catalyst technology and two HPE StoreOnce components:
- HPE StoreOnce Catalyst agent. The HPE StoreOnce Catalyst agent is a component of the HPE StoreOnce Catalyst software. The HPE StoreOnce Catalyst agent is embedded into the Veeam Data Mover Service setup. When you add a Microsoft Windows server to the backup infrastructure, the HPE StoreOnce Catalyst agent is automatically installed on the added server together with the Data Mover Service.
- HPE StoreOnce appliance. The HPE StoreOnce appliance is an HPE StoreOnce storage system on which Catalyst stores are created.
Veeam Backup & Replication uses two Data Mover Services:
- Data Mover Service on the backup proxy
- Data Mover Service on the gateway server
The gateway server is a backup infrastructure component that “bridges” the backup server and HPE StoreOnce appliance. The gateway server must meet the following requirements:
- The server must run Microsoft Windows OS (64-bit version)
- The server must be added to the backup infrastructure.
- The server must have access to the backup server and HPE StoreOnce appliance.
The gateway server is selected when you assign a backup repository role to the HPE StoreOnce appliance. You can define the gateway server explicitly or instruct Veeam Backup & Replication to select it automatically.
For HPE StoreOnce storage systems working over Fibre Channel, you must explicitly define the gateway server to communicate with HPE StoreOnce. As a gateway server, you must use a Microsoft Windows server that is added to the backup infrastructure and has access to HPE StoreOnce over Fibre Channel.
For work with HPE StoreOnce, Veeam Backup & Replication uses the Catalyst agent installed on the gateway proxy. If you want to reduce the load on the network between the source and target side, assign the gateway server role to a machine on the source side, closer to the backup proxy.
