This is your quick path to reliable, network Time Machine backups in 2025. Pick your route below—from “just works” to “maximum flexibility”—and verify your restore in minutes, not hours.
Start Here: Choose Your Path
- “I just want it to work” → Part 1: Official firmware routers
- “I’m happy to tinker & reuse my current router” → Part 2: DIY/OpenWrt
- “I’d rather use a different box (NAS/RPi/old mini PC)” → Part 3: Other devices
Compatibility Note
- Time Machine uses SMB now (AFP is legacy).
- macOS version and router/NAS firmware matter — always test a restore, not just a backup.
