Losing your library’s metadata can have catastrophic effects—as can losing keys in
any encryption key management system. If you lose all copies of all metadata:
Your encrypted data is lost—you are unable to decrypt encrypted data without
the encryption keys.
You need to completely reconfigure your library.
You lose stored data about your media that is time-consuming to recover.
