How do I change the location of the configuration data?

To change the location of the configuration data, include the following two bind mounts in your compose file:

volumes:
- ./config:/etc/proxmox-backup
- ./data:/var/lib/proxmox-backup

Replace the example paths ./config and ./data with the desired folders or named volumes.

Is the Raspberry Pi 5 supported?

Yes, but the Raspberry Pi 5 uses a 16k page-size kernel by default, which is incompatible with Proxmox Backup Server and can result in a 400 Bad Request: EINVAL: Invalid argument error when creating backups.

To fix this:

1. Edit /boot/firmware/config.txt on the host system.
2. Add the following line at the end:

   kernel=kernel8.img
   

3. Reboot the Raspberry Pi.

This switches the system to the 4k page-size kernel, which is compatible with Proxmox Backup Server.

Are there containers available for other Proxmox products?

Yes, see our Proxmox VE, Proxmox Datacenter Manager and Proxmox Mail Gateway containers.
