Proxmox Backup Client in Container Image

This image contains the Proxmox Backup Client for unsupported platforms.

Usage

1. Mount the desired backup directory to the container
2. Define the settings via environment variables according to the manual
3. Run the backup command in the cntainer

Example

I use ansible to create a podman container, mount the directory to back up inside. Then I turn the container into a systemd service, and create a timer to back up accordingly.

I also enabled podman-auto-update. In this setup, podman-auto-update doesn't work, since it only updates running containers, and all these contaienrs don't run constantly.
