About deploy pve worker on the air-gapped envirment

Hi Everyone,

 

I installed Veeam 13.1 on Windows Server 2022 without joining an AD domain and in an environment without internet access. I used IP addresses when adding the PVE9.2, but when I deployed the workers, the installation failed with the error “Veeam Updater is unavailable.” Later, I set up DNS forward and reverse lookups for the PVE and worker IPs, but the same error persisted. I unchecked the “Check for updates online” option for the workers.

Does Veeam require an internet connection for the worker to install packages?

Hi ​@nsofl.chen - no, Veeam doesn’t require internet access for worker installs. See below reference in teh Uesr Guide on Architecture for PVE & Veeam:

https://helpcenter.veeam.com/docs/vbr/userguide/pve_infrastructure_components.html?ver=13

There is a somewhat similar thread about Updater Service on v13.1 below:

Maybe reach out to Support, and monitor that post for resolution to see if what Support does helps your issue as well.

Best.

Thank you,

After reinstalling version 13.0.3.63, I’ve been using the backup LAN IP for everything without configuring any DNS A records or the hosts file. The worker installed and tested successfully, and backups are working normally.

I wonder if version 13.1.1.18 might have introduced some restrictions?

That's possible. Only Support would be able to answer that. 

Glad you at least got back to a working state.
