Put it another way -- a database that cannot be restored reliably from a point-in-time snapshot cannot be restored reliably if the system crashes.

This may be acceptable if there is a suitably reliable way of recreating the state of a database from external data. Usually there isn't.

See also crash-only software: if it's worth putting data into a database, it's worth being sure that the database is really crash-proof.
