I've just had a power-cut and on restarting, discovered that calibre's database was corrupt. Luckily I made a backup just a few days ago.

However, I have a couple of questions regarding rebuilding the database if I hadn't had the backup, from the files inside the library folder.

What filetypes aren't capable of storing all the metadata in them?

Would storing an *.opf file in the directory with each entry be able to store all the metadata needed to rebuild the database.

If it would, Could calibre do this automatically as a 'backup-redundancy' measure.
