I believe just the new books would be missing.

Then again if the thought bothers you, in addition to backing up your library / metadata.db file you could always save your books to disk w/metadata.

1. Go to Preferences - Add/Save - Saving books tab
2. Ensure that the following are checked.
Save cover separately
Update metadata in saved copy
Save metadata in OPF file
3. Click OK
4. In your calibre library select all books you wish to (backup) save to disk.
5. Select Save to Disk, create a new directory to export these books to, click OK.

Calibre is now exporting all the files you selected and any metadata or covers that you have updated/added.
After the intial save to disk if you add 10 books just select those 10 books and repeat the above steps to keep things up to date.

In the event of catastrophic failure you could start fresh and add these to calibre with the all of the metadata following along.

Personally, I just backup my library, the metadata.db file and the config directory.
