Data archiving system and method

Abstract

A data archiving device can be connected to a host device, and can include a version control system (VCS) unit configured to store archive data in a storage unit in response to the data archiving device detecting modifications to a host file of the host device. The archive data corresponds to the modifications and is processable to reconstruct previous versions of the host file. The VCS unit can be located in firmware that prevents overwriting and erasure operations in the storage unit by a user. The data archiving device can retrieve, upon receiving a request for a previous version of the host file, relevant archive data associated with the previous version of the host file. The data archiving device can forward the relevant archive data to the management device to enable the management device to reconstruct the previous version of the host file.
