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.
