Sorry for the delay in getting back to you. If you don't have a copy of the database file, then restoring your library is not going to be possible. Even if expose database is checked, it will not store the database file on an SD card, because this is inherently unreliable (the SD card might not be mounted when MobileSheets is loaded and the error handling could cause chaos with your library). Obviously this is ironic given this situation, but in general I still believe it to be true. Exposing the database does let you manually copy it elsewhere for safekeeping though (you could manually copy it to the storage location for example).
There is one thing you can try that might help a little. If you restore the older backup file, I'm assuming your storage location will still be set to the SD card and all of the files would be restored there. If you then turn around and batch import the storage location, it should ignore existing songs and import the missing ones. This might save you some time at least.
