Steady-state delta runs in 10-20 min and the weekly cadence left a real RPO gap: app data under /srv/nfs/<svc>/ that isn't a PVC (captured by daily-backup) or a *-backup CronJob (captured daily by the CronJob writing to /srv/nfs/<svc>-backup/) was on a 7-day worst case for off-disk durability. Affected paths include nextcloud shared files, audiobookshelf library, mailserver Maildir, calibre, servarr metadata, real-estate-crawler scraped data, openclaw agent state. Daily cadence drops their RPO to ~24h at negligible cost. Slot: 02:00, 3h ahead of daily-backup (05:00) so the manifest is populated before offsite-sync reads it at 06:00.
