Rescanning Storage Systems
You can rescan a storage system added to the backup infrastructure. Storage system rescan will help you discover these changes and update the storage system hierarchy in the Veeam Backup & Replication console. Storage system rescan can be performed automatically or manually.
[For VMware integration] Storage system rescan may be required, for example, if you create or delete snapshots on the storage system.
For more information about the storage system rescan process, see Rescan (Storage Discovery) Process.
Before you start storage discovery, make sure that you have a properly configured backup proxy in the backup infrastructure. [For VMware integration]: Otherwise, Veeam Backup & Replication will not be able to match storage volumes to VMware datastores and locate VMs on these storage volumes.
[For VMware integration]: Veeam Backup & Replication does not perform rescan on VMs whose disks are located on VVol datastores.
The storage system hierarchy can be very extensive, and the rescan process can take much time. To minimize the rescan time, you can instruct Veeam Backup & Replication to rescan only specific volumes.
To limit the rescan scope, open the storage system connection settings and navigate to the VMware/NAS/Veeam Agent Access Options step of the wizard. Select the volumes you want to rescan.
For more information, see Specify VMware/NAS/Veeam Agent Access Options step of the relevant Add Storage wizard.
