Both sync-sd-backup.sh and sync-usb-backup.sh used set -e, so rsync returning exit 24 (partial transfer due to vanished source files -- expected on a live root, e.g. a container's shm socket disappearing mid-sync) aborted the script before it printed its own success message, even though the actual file transfer completed fully. Only exit 24 is now tolerated; any other rsync failure still aborts as before. Found running sync-sd-backup.sh today: it transferred all 919k files correctly but exited non-zero and skipped its completion line.
