Backup Hyper-V over SAN

[roscomputers]

Hi all!
Im plan backup infrastructure for hyper-v vm's.
For examle, we have:
- HV cluster consisting of 8 nodes (Windows Server 2019 Hyper-V in core) (4 node in data center #1 and 4 node in data center #2).
- StoreOnce in data center #1 and data center #2.
- Tape in data center #1 and data center #2.
- Dedicated media server in data center #1 and data center #2.
I think deploy backup server in VM and consolidate backup jobs in one location.
For backup over SAN i must have dedicated backup proxy. And for storeonce i must have gateway server.

Can i use Hyper-V node in my Hyper-V cluster for this roles (on host proxy and gateway)?
Can i use Windows Server 2019 Hyper-V in core for this roles?
Can i use backup server in VM? What limitations in this scenario if i will use static backup proxy in backup jobs?

Thank you.

Hello,
and welcome to the forums.

Long story short: I would never do it. Always use On-Host proxy (especially for that environment size)

Which SAN are you using? Just to estimate how many issues you will have with hardware VSS providers...

Best regards,
Hannes

Since we are talking about proxy types, then off-host proxy cannot be part of the same cluster you're backing up VMs from.
