Abstract: A method and system for detecting ransomware and repairing data following an attack. The method includes, collecting file statistics for files in a file system, identifying an affected file based on collected file statistics, locking down of access to the file system in response to identifying the affected file, undoing of reconcile processing, repairing the affected files, and unlocking access to the file system. The system includes a computer node, a file system, a plurality of disc storage components, a backup client, a backup client, and a hierarchical storage client. The hierarchical storage client is configured to collect file statistics for files in file system, identify affected files based on collected file statistics for the file, lock down of access to the file system in response to an identified affected file, undo reconcile processing, repair the affected file; and unlock access to the file system.

Abstract: Operating a data processing and storage apparatus to perform continuous backup monitoring for a collection of stored file system objects. In response to changes respective to a number of the file system objects, a set of Data Management Application Program Interface (DMAPI) events is created. For each of the events, accessory file system object information relative to a file system object subject to the change is determined. The events are grouped into an event group and a unique group identifier and an overall group size count are assigned to each of the events included in the event group. The events are sent together with the respective accessory file system object information, the respective group identifier and the respective group size to a number of backup clients registered as applications. The backup clients are to process the events together with the respective accessory file system object information, the respective group identifier and the respective group size into a number of backup requests.
