No backup system can be a mathematical 100% guarantee — but this one uses SQLite's own consistent-snapshot mechanism and verifies every backup right after writing it. For real disaster protection (fire, theft, drive failure), periodically copy the "backups" folder to a USB drive or cloud storage too — a backup that only lives on the same PC as the original doesn't protect against losing that PC.
Manual backup
Creates a full backup right now — the database plus every enrolled person's photo, bundled as one .zip file. Includes devices, attendance history, and everything else in one file.
Automatic backups
Runs in the background as long as the server is running — checked every hour, so it self-corrects even if the server was off when one was due.
