We know that ReFS prioritizes data availability over everything else and it appears to do so via memory consumption. We might just need to take that into consideration when sizing repositories.
I just wanted to highlight this part, as you are spot on and some people often overlook this part. 4GB per job (sorry my bad as I wrote core following the reply, thanks Anton) is the requested sizing for Veeam repository services, not the entire system. If you have additional services, like the ReFS components, you need to add these additional requirements into the sum of the needed memory. For 16 cores, thus handling usually 16 concurrent jobs, you need at least 64GB for just Veeam, plus the OS and its services.
Thanks for remiding this!
