Hello community,
I've seen many customers using Veeam Backup Replication to back up vCenter Server Appliance VMs via image level backup.
According to this KB https://www.veeam.com/kb2328 "vCenter Server Appliance - Backup/Restore Recommendations" Veeam do not reccomends you to run image level backups againts VCSA.

You should use:

So, I created this procedure to show how simple it is to back up a vCenter Server Appliance using VMware's own backup tool, which we call "vCenter Native File-Based Backup and Restore."
Check out this link for details:https://techdocs.broadcom.com/us/en/vmware-cis/vsphere/vsphere/7-0/vcenter-server-installation-and-setup-7-0/file-based-backup-and-restore-of-a-vcenter-server-environment.html
First of all, you must create a destination for the backup file, the destination could be accessed by several protocols, the protocols supported for backup are FTPS, HTTPS, SFTP, FTP, NFS, SMB and HTTP.
I just created a folder called C:\Backup_VCSA on my VBR itself, and just share it !

Secondly, using the VAMI interface, I configured the backup using file-based backup.
Access the port number 5480 of your VCSA https://VCSA_IP:5480 , after login in, you can select the backup option and than, configure.

Now, you just need to configure the backup on the next screen.

Backup Location:
Enter the backup location, including the protocol to use to connect to your backup server, the port, the server address, and backup folder to store the backup files.
Use one of the following protocols: FTP, FTPS, HTTP, HTTPS, SFTP, NFS, or SMB.
For FTP, FTPS, HTTP, or HTTPS the path is relative to the home directory configured for the service.
Backup Server Credentials:
Enter a user name and password of a user with write privileges on the backup server.
Schedule:
Set the schedule recurrence and time for the backup.
The recurrence can be set daily, weekly, or you can customize the schedule to run the backup on a specific day or days of the week. You can specify the time of day to run the backup. The default time is 11:59pm.
Encrypt backup:
Enter an Encryption Password if you want to encrypt your backup file.
If you select to encrypt the backup data, you must use the encryption password for the restore procedure.
Numbers of backup to retain:
Select Retain all backups or enter the number of backups to retain.
The retention information provides the number of backups to retain for a given vCenter Server
.
Data:
Supervisors Control Plane (available on v8) The VMware Supervisor's control plane is a native Kubernetes control plane built directly on the vSphere hypervisor layer, which manages the creation and lifecycle of Tanzu Kubernetes Grid (TKG) clusters and workloads. It is enabled on a vSphere cluster and utilizes vSphere resources for its own operation and for the provisioning of Tanzu Kubernetes clusters, which run as virtual machines on the ESXi hosts. This integration allows vSphere administrators to manage Kubernetes resources through the vSphere Client and provides developers with Kubernetes environments that are integrated with the underlying vSphere infrastructure
Stats, Events, and Tasks
Inventory and configuration
As soon as the backup completes, you can see the backup media on the share.

Now, your VCSA is safe, in order to restore it, you just need to follow the procedure available on this link:

Hope that help!
