Hi all, I'm trying to wrap my head around licensing in my specific scenario (and maybe some advice on how to best set this up). For context: in terms of servers and virtualization, i only really have experience with Proxmox VE and Linux servers. I have extensive knowledge about Microsoft cloud systems and licensing, but i've never touched on-prem licensing before.

One of our customers needs a server for an application provided by a third party. This party is wildly unhelpful with giving us technical details about the hardware and software requirements.
What we have gathered:

• Windows 11/Windows server 2022
• 16GB RAM
• 2 cores
• SQL Server 2022

The application pulls (or gets pushed) data from Dynamics 365 Business Central (cloud version) through an API, processes it (which uses SQL server), and sends it off to a PLC which belongs to an OT system.
Other than administrative purposes, no users will be directly interacting with the system as far as i understand it. Users interact with Business Central, and i'm pretty sure users interact with the OT system (manually starting machines, etc.).

The amount of users interacting with Business Central and/or the OT machines is roughly 50.
There is no on-prem servers already available.

So my current plan is to deploy a Server 2022 box, i have options for 4C/4T and 6C/12T, with 6C being only slightly more expensive.

My current understanding, is that for Windows Server Standard i must have a CAL for every user, and for SQL i can choose between a per-core licensing or server+CAL.

My questions:

1. Do i need Windows Server CALs for every user in this scenario?
2. Does Business Central or the OT system count as a multiplexer in this scenario? (which means i need CALs if i don't license per core)
3. What would likely be my cheapest option? In this case i'd prefer a bare-metal install, but i'd be willing to use Proxmox VE or Hyper-V if that provides significant benefit or cost reduction.
4. Do i need Software Assurance for any reason in this scenario?

Thanks in advance!

I'm trying to configure Azure backup for Blob Storage, and i keep getting this error during validation: DppStorageBlobPluginInternalError

I've confirmed that the storage vault has the required permissions on the storage account, i checked that there's no orphaned protection or backup metadata, and i waited a day for permissions to propagate.

I also disabled all data protection policies, but the backup still wouldn't activate.

Can anyone point me in the right direction?
