Description=Weekly Media -> Backup pool copy

[Timer]
# Saturday 05:00. Clear of: the cron.daily zfs-auto-snapshot window (03:22-03:52),
# timeshift (04:00), arr-queue-reconcile (04:31), and both ~/Server backups (01:00, 02:00).
# Saturday specifically because Monday carries the Media scrub and Sunday has
# raid-check (01:00), docker-prune (05:33) and dind-prune (06:03).
# gib also runs Nextcloud's borg by hand roughly monthly and is, in his words,
# not going to be doing that at 5 AM on a Saturday -- so the borg lock should be free.
