Clarification regarding backup proxies/offloading snapshot creation

[glamdring]

Hey all,

Here's our situation. We got a new SAN exclusively for Veeam backups. I've got a backup job targeting a Hyper-V cluster. 80% of the VMs backup successfully. The few that don't complain that there isn't enough storage to create a snapshot. I was hoping the backup proxy feature would help solve this, but it appears that really only helps reduce resource consumption on the Hyper-V hosts.

My question: is it at all possible to have snapshots generated somewhere other than on the host, or is this a Hyper-V limitation I will need to live with?

I've read the documentation and saw some conversations here, but wanted to be 200% sure before we purchase additional storage, etc.

Thanks!

Please see Microsoft documentation here: https://learn.microsoft.com/en-us/virtu ... t-location

In general it is NOT a best practice to place them on different disks, specifically when you do this for all VMs targeting Checkpoints to the same disk (it would become likely a bottleneck). But I think it is OK in specific cases like yours where you ran out of space on some VMs.

Awesome, thank you tons Andreas. I'll give that Learn article a good read and do some experimenting. Cheers!
