Nextcloud Debian 12 Server

Overview

This project documents a personal, self-hosted Nextcloud instance running on a headless Debian 12 server. The primary goal is to migrate and maintain the majority of personal data off third-party cloud services (notably Google Drive) while maintaining reliability, security, and simplicity.

The system is designed to be:

• LAN-only by default
• Secure by design
• Boring, maintainable, and scriptable
• Independent of all external cloud services

This server is intended for single-user use only.

High-Level Goals

• Replace Google Drive with a self-hosted Nextcloud instance
• Maintain full control over data storage and access
• Ensure strong backups and recoverability
• Keep the system understandable and rebuildable from documentation alone

NOTE TO FUTURE ME:
If this server ever fails catastrophically, this repository should contain everything needed to rebuild it from bare metal.
