VM with Virtual Fibre channel data

Post by RHITDEPT » Aug 07, 2019 12:56 pm

Dear forum,

I have a question regarding Veeam' s ability to backup a guest VM's data, when the data is stored directly on the SAN, and accessed by virtual fibre channel on the VM.
Will I need to backup this VM with a Windows agent? Or will the Off Host proxy be able to deal with it as part of a normal Hyper-V VM backup?

Environment:
Hypervisor - Hyper-V failover cluster (2016), 3 hosts, Clustered Shared Volumes
Backup method - Off host Proxy
Production SAN Storage - HPE 3PAR 7200c
Backup Storage - HPE StoreOnce
Veeam Backup & Replication Version - 9.5.0.1922

Virtual Machine in question:
O/S - Windows Server 2016 Datacentre.
Role - File server (part of a fileserver cluster)
Storage - O/S Disk is stored on a Hyper-V Clustered Shared Volume, and the DATA disk is direct SAN attached (access via virtual fibre channel).

Any advice would be welcome.

Regards,
Ben Holland

Hello,
yes, the Windows agent is the way to go.

Backup & Replication can backup every machine where you can create a Hyper-V / VMware snapshot (virtual machines). As this is not possible with "half" physical machines (like yours with raw device mappings / virtual fibre channel), you need to treat them like physical machines.

Best regards,
Hannes

Thanks for confirming that Hannes,

One other question on that basis then.

Can I do 50/50? In other words do the O/S disk backup using Hyper-V/Veeam snapshots, and the DATA disk (direct SAN attached) backup using the agent on the VM.
This will limit slightly the amount of network traffic during the backup on the VM.

Regards,
Ben

Hi,
no, Hyper-V does not support that. You could switch to VMware. It works there ;-)

Best regards,
Hannes

Hi,

That's a shame..
It's not worth me changing my whole virtualisation platform just for that.

I will just use the Agent to backup the Data disk.
The data is what's important, I can always just spin up another Windows server O/S and restore the data if needed.

Thanks for your help.

Regards,
Ben
