Hello,

I was working on setting up VB365 for our smaller company and had some questions about setting up the NATS server. We are using a single proxy server that is set up on the same server that the VB365 console is running on. We will mainly be backing up M365 mailboxes to object storage for a handful of users.

I read here, “The NATS server ensures communication between backup proxy servers that you group into a backup proxy pool.” Since we aren’t using a proxy pool, and just a single proxy server, is NATS still relevant? I ask because I noticed that in the installation instructions here that it reads, “Important: By default, the NATS server that you deploy along with Veeam Backup for Microsoft 365 on the target machine does not use the TLS encryption.” Should I set up the NATS server to use TLS, or does it not apply to our setup?

Thank you in advance for any help.

NATs is still relevant and will be installed on the VB365 server locally to be used.

Follow this page for TLS - https://helpcenter.veeam.com/docs/vbo365/guide/vbo_upgrade_configure_nats.html?ver=80

For smaller deployments ( <2000 users) you should be fine with a next, next, finish installation with an all-in-one setup. NATS is still necessary and relevant, without NATS, the system will not work.

Apply the GOMEMLIMIT to keep memory consumption of the NATS server under control (75% of available memory as a maximum)

 

Thank you for the replies.

Are you saying that I don’t need to bother configuring TLS and just leave it how Veeam configures it during the installation process?

I tried following the instructions from the NATS website, but I’m not familiar with NATS. Am I supposed to edit the nats-server.conf file in ProgramData? I can create a separate NATS server and connect to it just fine, but I can’t figure out how to configure the one that Veeam already set up upon installation. Would you be able to point me in the right direction for this?

I believe that is the file you need to edit.  I have deployed VB365 V8 but with external NATs versus the built-in one so not 100% sure.  There has to be a conf file though somewhere on the controller.
