# Consistent SQLite snapshot of the arbo gallery DB, run before the restic backup.
# Uses SQLite's online-backup API (safe under concurrent writes) to write
# gallery.sqlite.bak INSIDE the arbo_db volume — which is already a restic
# source (/var/lib/docker/volumes), so the consistent copy rides the daily run.
# NON-FATAL by design: a failure here (e.g. container down) must NOT abort the
# host's sole backup, hence the trailing `|| true`.
