Alert admins of database changes without a backup.

Rather than back up the entire database, we can use LogEntry to identify models that have changed, and to dump their information to a json file.

We should alert admins when a LogEntry has a newer date than the json file.

Can you provide more details? I feel like a dumb/simple approach is better than a smart/complex approach when it comes to disaster recovery.

I'd be afraid this would complicate the restore process. Right now it's a simple gunzip backup.sql.gz | mysql command to restore. If we're dealing with json paritals, how do you apply them once the schema has changed?
