Backups are .tar.gz archives of a consistent database snapshot (VACUUM INTO) plus the images folder. They run on a cron schedule, daily at 3:00 by default, and the newest N scheduled ones are kept (7 by default). Manual backups are never pruned. Settings → Backups offers schedule presets or a custom cron expression, retention, "Back up now", and download/delete for each backup. A small built-in parser handles standard 5-field cron syntax with names, ranges, steps and @daily-style shorthands. Backups go to CANON_BACKUP_DIR (default data/backups). Compose mounts a separate canon-backups volume at /backups, overridable with CANON_BACKUP_PATH. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
