How do we restore a server if the Veeam server is also down?

Can you not deploy a new server. Install Veeam, Import the config and proceed as normal to do a restore.

Or even instal Veeam attach the repository and import the backup?

Hello 
SAme approach than ​@MarkBoothman . 
If your Veeam Server is down the easiest way to recover one is to deploy a new one and import the backup config and reattach your repository. (but in the case you have lost your VBR your repository may be impacted too) 
Do not forget to have backups copies in another site

If the Veeam server is down then you cannot restore.  You need to do as others have suggested a new server and restore configuration backup then restore.  Hopefully your repository is good for the files.

i would go with Mark, Philippe and Chris 😀
You can check Veeam Configuration Backup Restore Steps and Restoring Configuration Database for details, or just ask here.

Another approach would be to virtualize your VBR server and perform replication on that VM to build a redundancy. You shouldn’t use a Veeam Agent on the VBR server itself so I agree with all above comments: Configuration Backup and restore is the key.

Virtualization could be another idea, but this is all about architecture design.

Thanks everyone for all your answers. If I’m understanding correctly, the solution when one of our servers goes down is to reinstall a new copy of Windows on the server, then install Veeam on the server, then restore the server from a Veeam backup. Am I understanding that correctly? This seems like a bit of a long way around… Is there not an option in Veeam to create recovery media like an ISO file which can be used to boot the server without having to completely reinstall Windows and Veeam?

Basically you need a Windows with a Veeam (VBR) installation and within the “fresh” VBR you import the Veeam configuration backup. This is a “special” backup in the main menu of Veeam that contains the Veeam settings and contents of the Veeam config database. Basically this is all you need.

You can either have a “backup” server with a pre-installed Veeam online so you just need to import the config backup (please use the most recent backup) and you are ready to go or you can do these steps (Windows Server OS installation and VBR installation) when a disaster is happening.

Please consider - in case that is possible - to run VBR within a VM. With a VM you could use replication to aviod reinstalling anything in case of a disaster.

Using an ISO would not allow you to do what you want and why you need to reinstall the server. As noted having a secondary server with Veeam installed ready to go.

Hello ​@AdamL,

may seem like a long or complicated procedure, but it is simpler than it may appear to you.

You can also install VBR on your PC if you do not have the resources to create a VM.
All of us who use Veeam on a daily recommend this path.

Hello all,

When you guys talk about restoring Configuration Backup, are we talking about .bco files? Is there any database file needed to be backup too?

The BCO files contain the backup of the Veeam configuration database. So there's no need to create a dedicated database backup.

https://helpcenter.veeam.com/docs/backup/vsphere/vbr_config_restore.html?ver=120

When restoring a Configuration Backup in Veeam Backup & Replication, the primary file used is the .bco file. This file contains all necessary settings, including job configurations, repositories, and infrastructure settings.

Veeam does not require a separate database backup because the .bco file already includes the database structure and data needed for restoration. However, if you are using an external SQL database instead of the default Veeam SQL Express instance, it is recommended to back up that database separately for additional redundancy.

For detailed steps on restoring the configuration, refer to the official documentation: Veeam Configuration Restore Guide.
