Please note that Windows Server 2019 support is coming in Veeam B&R 9.5 U4, so using it as repository with the current version is not recommended at the moment.

Welcome to the forums, @supradiz - Foggy has it right. Just for background - Veeam takes platform support very seriously - and WS2019 testing is underway from a product perspective. The expectation for Veeam in the market is what I would call full and complete WS2019 support, which will include:
-Installing Veeam console on (WS2019)
-Installing components (proxy, repository, WAN Accelerator, etc.) on
-Hyper-V 2019 for backup & replicas
-Guest VMs on VMware and Hyper-V backing up and replicating
-REFS as you indicate as well is a scenario to check thru

Theses are just some of the situations off the top of my head. It is all underway but it is a comprehensive matter and the expectation we have given to key partners like Microsoft and VMware is that Veeam would support the newest platforms within 90 days of their release.

Any news regarding server 2019 deduped refs volumes ??

I guess dedupe will definitely save some more bytes as fastclone alone, as when you just imagine using perVM Backup the Core Operating System Files still get backued multiple times...

The only question is if there is still the 1tb dedupe filesize limit, as this would make it useless for backups again.. (as long Veeam don't split perVM in per disk backup files, even then it's not say'd that there isn't ah big single disk with more then 1tb :( )

Hi DaStivi,

We will have experimental support for it in Update 4, by using a registry key to enable this functionality. Those details will included in the What's New document.

Thanks!

"Microsoft actually supports looking at the first 4 TB of a file for Deduplication on ReFS." Reference comment by Dave Kawula
