Account: Entra ID or Shared Key?

[jorgene]

Hi, i've been playing around with Veeam Vault for a couple of weeks or so to test the immutability function.
We purchased through a distributor and got access to a subscription.
I've used shared key when setting up the account to access the VDCV from the respository from the VBR server.
But after i upgraded to 12.3.1.1139 now below managed servers it lists the server as Out Of date. And upgrade pushes me to Switch to Entra ID authentication.
So what is the best thing to do here? I can authenticate to the Entra ID with my veeam account.(tested on LAB VM). But what does it really do when Authorizing backup server?

Can i stay on using shared key or should i switch to Entra ID Authentication?

Hello!

It is better to switch the authentication method to Entra ID from the security prospective. This authentication model is generally recommended by Microsoft, substituting the old Shared Key model. What happens under the hood - VBR registers a special Entra ID application on the cloud side, setting the configuration automatically. This application can be considered a "service account" that is used in communication between VBR and VDCV.
