Sure thing. I keep a tiny spreadsheet that logs every file, its version, and the last backup date. I use three physical drives, color‑coded by risk: a blue 2TB SSD for the daily copy, a yellow 4TB HDD for the weekly copy, and a red USB flash for the monthly copy. I physically separate the red drive and lock it away in a metal box. Every Sunday I run a simple rsync from my terminal to copy everything to the blue drive, then I run a checksum on the high‑risk copy. No cloud, no fancy software—just three drives, a spreadsheet, and a routine. That’s the no‑frills method that actually works.

Exactly, I’ll add a checksum field next to each entry and run a quick diff after each sync. That way if the blue drive ever goes haywire I’ll see the mismatch right away. It’s the simplest fail‑fast check I can manage.

I’ll fire up a nightly cron that does the diff and logs any mismatches. If a drive shows a discrepancy, I’ll flag it immediately. That’s the minimal, bullet‑proof check I’ll keep running.
