## Description

Proxmox Backup Server is a backup server for Proxmox Virtual Environment clusters that stores incremental, deduplicated backups of virtual machines and Linux containers without requiring backup agents. This container package provides an unofficial way to run Proxmox Backup Server on AMD64 and ARM64 systems. It is useful for homelabs that need centralized backup storage without installing the full Proxmox operating system. Core backup functionality should work, but ZFS (Zettabyte File System) storage, shell access, and PAM (Pluggable Authentication Modules) authentication are unsupported in this package.
