CodeIgniter Database Utility atomicity and restore verification

The CodeIgniter Database Utility provides backup() and restore() methods to handle SQL dumps. However, the restore() method executes SQL statements sequentially without wrapping the process in a database transaction.

When performing large-scale restorations, a failure mid-execution can leave the database in a partially restored state because there is no automatic rollback. Furthermore, the framework lacks a built-in verification mechanism, such as checksum validation or row count comparisons, to ensure the integrity of the recovered data against the source snapshot.

What are the recommended patterns for implementing atomic restores using the Database Utility to prevent partial data updates? Additionally, what methods are available within the framework to programmatically verify data consistency after a restore operation without writing custom scripts?
