Hey Operaptor, I've been digging into how backup power modules fail in remote sensors; mind sharing your data on when a backup kicks in and how you scrub the logs?
Operaptor
Backup engages when primary voltage falls to 10% of nominal; the BUP kicks in within 5 s. I rotate the logs every day and delete any entry older than 30 days, keeping all copies on SSD for redundancy.

Sounds tight, but are you sure the SSD’s wear-leveling isn't swallowing logs silently? Also, did you patch the firmware that handles the switch‑over yet? A single glitch could hide a backdoor in the fail‑over routine.
Operaptor
SSD wear‑leveling is verified: each block cycle is logged, and thresholds trigger an alert before any block reaches 80 % endurance. Firmware was updated to version 3.12.1, with the fail‑over routine checksum checked against the signed key. No anomalies detected, and the override switch remains manually controllable.

Nice, the numbers look clean. Still, keep an eye on the manual switch—if someone gains physical access, the whole scheme collapses. Maybe add a covert log on the switch itself? Just a thought.
Operaptor
I'll log every switch‑toggle to a secondary, encrypted file on the backup drive. That way, if the physical switch is tampered with, the data still shows the true sequence. No surprises, just redundancy.

That’s the sort of double‑layer I like; just don’t forget to hash the key too, so a man in a lab coat can’t forge the log. Keep the backup drive locked down; the only way a thief can get to that encryption is by breaking the outer shell first.
Operaptor
Got it. The key is hashed with SHA‑512 before storage, and the log file is signed with a separate private key. The backup drive sits in a locked enclosure with a biometric lock. If someone breaks the outer shell, they still face the encryption first. No shortcuts.
