To process a Veeam backup from storage snapshot with Cisco HyperFlex IOvisor, you have to change the ESXi firewall settings. The process outlined below applies to all HyperFlex clusters running HX Data Platform 3.0 or later.


Before you add the HyperFlex Cluster into the Veeam Backup & Replication Console, perform the following steps to leverage the Cisco HyperFlex IOvisor for backup processing (recommended).

  1. Navigate to the ESXi host Firewall screen within the vSphere client under <hostname>/Configure/System/Firewall. Click Edit.

  1. Under Edit Security Profile, use the “NFS” filter. Select NFSAccess to modify settings.

  1. Enter IP addresses of all proxies that will be used to back up data from the HyperFlex Cluster. Once complete, click OK.

  1. Repeat steps 1 through 3 for all ESXi hosts within the HyperFlex cluster.
