Overview

Develop a backup system capable of saving and restoring the state of each LXC container setup in the homelab. The system should provide comprehensive mechanisms for backup and restoration of key container data, including Docker volumes and configuration files. Backups should be stored in dedicated drives.

Requirements

State Preservation: Save the complete state of each LXC container, including all relevant configuration and runtime data.
Per-Service Packaging: For every LXC container, package and compress Docker volumes and configuration files on a per-service basis, allowing selective restoration when needed.
Restoration: Provide a way to restore the state, volumes, and configs of each container in a reliable and user-friendly manner.
Adaptability: Design the system to accommodate changes in container setup, supporting future scaling or modifications.
Storage: Store all backups on dedicated drives to ensure data isolation and integrity.
Documentation: Prepare comprehensive documentation covering:
- How backups are performed
- How restorations are carried out
- How to configure and adapt the system for new containers/services

Acceptance Criteria

Functional backup workflow demonstrated for multiple LXC containers
Successful restoration of container state, volumes, and configs
Backups confirmed to be stored in dedicated external/internal drives
Clear, step-by-step documentation for users and maintainers
Modular design to facilitate later enhancements
