If you define table type as InnoDB, you can use transactions (see the link below). You
will need set AUTOCOMMIT=0, and after you can issue COMMIT or ROLLBACK at the end of
query or session to submit or cancel a transaction. I don't think you can use
transactions for mysql system tables because they have to be MyISAM type, so the best
solution for them will be backups.
