Is there an option to backup the library metadata database and the library structure (i.e. the folders), without backing up the whole library, i.e. the ebook files themselves? Specifically, backing up the folder structure, the metadata.db, metadata_db_prefs_backup.json, and the .opf files in each folder?

The reason for asking is this: Calibre manages the library by managing those metadata files aforementioned. The actual ebook files themselves (the .epub) are seldomly altered. The danger of a corrupted library lies in the database, not the ebook files. Meanwhile, backing up the whole library folder is quite heavy.
