Rescanning Storage Systems
You can rescan a storage system added to the backup infrastructure. Storage system rescan gets and updates the information that is necessary for the backup, replication and restore processes. Storage system rescan may be required, for example, if you create or delete snapshots manually on the storage system, not using Veeam Backup & Replication. It also updates a storage system hierarchy in the Veeam Backup & Replication console. For more information about the storage system rescan process, see Rescan (Storage Discovery) Process.
Storage system rescan can be performed automatically or manually.
Before you start a storage rescan, make sure that you have a properly configured backup proxy in the backup infrastructure. Otherwise, Veeam Backup & Replication will not be able to collect data about VMs in the snapshots for which VMFS or NFS rescan is required.
Veeam Backup & Replication does not perform rescan on VMs whose disks are located on VVol datastores.
Rescan of the whole storage system hierarchy 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.
