# 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).
