Your backup strategy is probably broken, and a $250 second machine can fix it

Relying on a single NAS for backups is risky — RAID failures, accidental wipes, or physical disasters can wipe everything. A practical solution is adding a cheap secondary machine (around $250) as a remote backup node. Using Tailscale for secure connectivity (even on CGNAT setups), snapshot replication can be scheduled every fortnight or monthly with a 6-month retention policy. Even a Raspberry Pi or a budget NAS like the UGREEN NASync DH2300 is sufficient for a proper 3-2-1 backup pipeline, consuming only 10-20W when configured with power-saving settings.
