I need some advices for a new setup with VSA and Proxmox.
The setup :
1 cluster with 2 Proxmox node with 1 volume for the OS and 1 volume for the storage of the VM
The storage is done with Datacore Sansymphony (HCI solution).
1 VSA + 2 worker + 1 VIA repository for backup + 1 Synology NAS NFS for backup copy
I read Veeam documentation and limitation and I have 2 mainly questions :
The Snapshot storage must be file level storage. In my scenario, that mean I need to use the volume available on the same disk as the OS right ? Because the storage used for the VM will be block storage …
For the worker, same issue if I understand it correctly, it must be file-level storage that supports snapshots. That mean I also need to use the same volume right ?
How do you usually manage it ?
Finally, for the File system of it, do you use ZFS or XFS or EXT4 ?
Thanks for your answer

I just read something I don’t like a lot, SAVC is “preview feature”.
Do I have an other solution maybe ?
I’m thinking about Datacore plugin for storage snapshot...
I’d think shared NFS or Ceph RBD then probably if skipping LVM /w SAVC.
Shared NFS is not possible with Sansymphony but Ceph RBD could.
Just for me to know, Why not ZFS here ?
I just read again the previous picture I added and I can see ZFS and Ceph RBD both provide block storage and snapshot support.
ZFS over iSCSI could work but local ZFS pools are not shared on PVE. To make ZFS/iSCSI work you’d need an appliance that supports the SSH connections from Prox etc. I guess you could give each node its own ZFS pool and use Prox replication but then you are also changing the design around.
With the storage you have SAVC is still my first choice. NFS with a gateway device would be my second. For Ceph you’ll need 3 nodes.
Thanks for the explanation of SAVC. Trying to wrap my brain around how that works. 🤔😅
I’m looking more into PVE this yr as well because I think we “may” be going to it from VMW next yr. Not looking fwd to a full migration, but it is what it is. Thanks guys.
I did a 12 part series on PVE 9.1. Might be worth your time. - 🤝
You're absolutely right, Damien. Moving from vSphere to Proxmox brings a different set of storage management challenges, especially when you want to Veeam to manage snapshots via the API or external plugins.
Since you are already looking at SAVC as a "preview" feature and want to more stable/standardized options, I would suggest focusing on what is/can be shared across your nodes. If you can't use NFS from the Sansymphony array, but Ceph RBD is an option for you, that provides built-in replication and snapshot capabilities natively within the Proxmox ecosystem.
Just a quick question to help narrow down the possibilities: Are you planning on using a dedicated network for your Ceph OSDs/replication traffic, to ensure it's not competing with your VM production traffic or backup traffic?
