Step 4. Specify Veeam Agent Access Options
At the Server Storage step of the wizard, specify options for accessing the storage system. You will see this step if you selected the Block storage for Microsoft Windows servers check box at the Specify HPE 3PAR Web Services API Address and Storage Role step of the wizard.
- In the Protocol to use section, select check boxes next to protocols over which you want to work with the storage system.
- If you plan to work with specific storage volumes, you can limit the storage rescan scope. In this case, Veeam Backup & Replication will rescan only the volumes that you select. Limiting the rescan scope reduces the amount of time required for the rescan operation.
To select volumes to rescan, click Choose to the right of the Volumes to scan field. In the Edit Volumes window, select volumes you want to rescan:
- To exclude volumes from rescan, select All volumes except and click Add. Click From infrastructure to select volumes from your storage infrastructure, or By wildcard to select volumes using a wildcard character.
- To rescan only specific volumes, select Only the following volumes and click Add. Click From infrastructure to select volumes from your storage infrastructure, or By wildcard to select volumes using a wildcard character.
- If you leave All existing volumes check box selected, Veeam Backup & Replication will rescan all volumes in the storage hierarchy.
After you finish working with the wizard, you can change the rescan scope and start the rescan process manually at any time. For more information, see Rescanning Storage Systems.
If you plan to use Backup from Storage Snapshots, you need to make sure that you include in the rescan scope the volumes on which the protected machine disks reside.
- To rescan storage systems and perform Backup from Storage Snapshots, you need to configure a backup proxy. On the right of the Backup proxies to use field, click Choose and define backup proxies that you want to use for these operations.
- Select Automatic selection to let Veeam Backup & Replication pick a backup proxy automatically. Veeam Backup & Replication will check which backup proxies have access to the storage system, and automatically assign an optimal backup proxy for rescan and Backup from Storage Snapshots.
- Select Use the selected backup proxy servers only to explicitly select a backup proxy that must be used for rescan and Backup from Storage Snapshots. It is recommended that you select at least two backup proxies to ensure that rescan and Backup from Storage Snapshot are performed if one of backup proxies fails or loses its connectivity to the storage system.
If you select backup proxies explicitly, you must make sure that you also select these proxies in settings of backup and replication jobs for which you plan to use Backup from Storage Snapshots. If a backup proxy selected for the job is not added to the list of backup proxies in the storage system connection settings and the Failover to standard backup option is disabled in the job settings, the job will fail.
