SetNextBackup counted "tomorrow" from the day the server started, using the newest backup file as the last backup, so a restart between midnight and the backup time (every Thursday reboot), a manual backup, or a backup finishing after midnight skipped a day. The next backup is now simply the next time the backup time comes round on the server's clock. A time that happens twice when the clocks go back runs at the first one only. Tested with a minute-by-minute simulation over both daylight saving changes (one backup every day; the old code skipped days) and on the local server. Changelog line; two Deferred entries (dead inputs, safe headers missing on handler 500s). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
