Self-hosting does not have to mean building a data centre. Start with one service that solves a real problem: a media library, photo backup, password manager or notes system.
Keep the design boring:
- Use hardware you already own.
- Run one service at a time.
- Keep application data separate from the operating system.
- Back up configuration and irreplaceable files.
- Test restoring something before you need it.
- Use friendly local names and HTTPS.
- Document the few commands that matter.
The goal is not to replace every cloud service. The goal is to make sure a company closing an account does not erase your only copy of your life.
