The backup script missed DATA_DIR when the line carried an export prefix, quotes, padding or a CR, and silently fell back to ./data — dumping first and only then discovering there was nothing to mirror. It now strips all that, prints the paths it's using, and stops before writing anything if the files folder isn't there. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
