Those backup files (metadata.opf) are used to restore the database in case of database corruption.

Where were these books you "added" back?
In the future, backing up your entire calibre library directory saves all of your books and metadata. Restoring that directory and pointing the new install of calibre to that directory will give you all of your books and metadata exactly as it was before the reformat.
