US Patent 12079088 Hybrid technique to protect a registry

A registry writer is instructed via a copy service on a host to prepare for generation of a snapshot. The registry writer is responsible for saving system hive files to disk before the snapshot is generated. A reporting of the system hive files is received from the registry writer. Communications are exchanged with an API exposed by an operating system of the host to identify user hive files. The system hive files reported by the registry writer and the user hive files identified using the API exposed by the operating system are backed up from the snapshot to secondary storage.
