# Weekly SkateSpots relay archive + optional offsite copy.
#
# Driven by the systemd user timer `skatespots-archive.timer` (install with
# scripts/install-archive-timer.sh). Local archives land in
# ~/.backups/relay; if ~/.config/skatespots/restic.env exists, the whole
# directory is pushed to a restic repository (S3/R2/B2/SFTP) and old snapshots
# are pruned. Without that file the archive is local-only — still useful, but
# not a real offsite backup.
#
# Manual run / debug:
#   scripts/backup-relay.sh
#   journalctl --user -u skatespots-archive -n 50
