Not that specific file system no.  If there VMs on it they can get backed up.

Hi @Asad Raza -

Are you referring to backend storage system? Veeam doesn't state specifically Scale GPFS is supported, but does say they support Spectrum Virtualize OS v8.2+. See below:

https://helpcenter.veeam.com/docs/backup/vsphere/system_requirements.html?ver=120#ibm-flashsystem--formerly-spectrum-virtualize--includes-ibm-storwize-and-ibm-svc-

As far as VM guest OS goes, Veeam only supports those OSs the hypervisors support, and I don't believe that one is supported by VMware. (see Guest OS support below) 

https://helpcenter.veeam.com/docs/backup/vsphere/platform_support.html?ver=120#vms

Pretty sure other hypervisors don't as well (HV, NTX, etc)

The only Agent Veeam supports for IBM is AIX:

Hope this helps. 

IBM Spectrum Scale is not officially supported by Veeam and all special functions of this parallel filesystem will not be used for a backup with Veeam.

You can do a backup of an exported Spectrum Scale share with Veeam NAS backup or with Veeam Agent.

Full support for Spectrum Scale have the IBM backup products only - as far as I know.
