Add a litestream service (0.5.17) to the compose stack that streams /data/mealquest.db over SFTP to the Synology NAS with a dedicated key, daily snapshots kept for a week. Add a systemd timer that rsyncs the media directory to the NAS nightly at 03:30. Task: d2f2e87e-5114-4ef1-93ab-360ffb5c009e Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# Nightly copy of the MealQuest media directory (recipe and dinner photos)
|
|
# to the Synology NAS. The database itself is replicated continuously by
|
|
# Litestream; this covers the files beside it.
|
|
#
|
|
# rsync mirrors the media directory onto .../mealquest-backups/media/ only:
|
|
# both paths end in a slash, so --delete removes files from that target
|
|
# directory and nothing outside it. A missing source directory (no media
|
|
# uploaded yet) is reported and skipped, never synced, so an empty source
|
|
# can never wipe the remote copy. Re-runs transfer only what changed.
|
|
#
|
|
# The volume is writable by the app container, so a media path that is a
|
|
# symlink is refused: root's rsync would otherwise follow it and copy
|
|
# whatever it points at. Symlinks inside the directory are copied as links
|
|
# (-a), never followed.
|
|
#
|
|
# Connects with the dedicated MealQuest key; the NAS host key must already
|
|
# be in root's known_hosts (StrictHostKeyChecking=yes fails otherwise).
|
|
# Installed as /usr/local/sbin/mealquest-media-backup; output goes to the
|
|
# journal via mealquest-media-backup.service.
