An engineer needs to back up their VMware VMs running on a Nimble Array.

To enable backup from storage snapshots with a Nimble Array, it is necessary to add the storage system to the Veeam Backup & Replication console's Storage Infrastructure. This allows Veeam to interact with the Nimble Array and orchestrate the creation of storage snapshots, which can then be used for backups. Simply enabling the backup from storage snapshots option in the job is not enough; the array itself must be integrated into the Veeam infrastructure.References:
