Abstract: A computing system includes a memory device, a persistent storage device, and a processor. The persistent storage device includes a filesystem having filesystem objects and a protection system stored thereon. The protection system includes a filesystem minifilter driver and a protection service. The minifilter driver intercepts an input/output (I/O) event directed to a target filesystem object and extracts system event metadata from the I/O event. The system event metadata includes an identifier of the target filesystem object. The system event metadata is transmitted to the protection service and recorded in a record file. A backup copy of the target filesystem object created. The I/O event is released after recordation of the system event metadata and creation of the backup copy, thereby enabling the I/O event to be performed on the target filesystem object. During a system restore operation, the target filesystem object is replaced with the backup copy.

Abstract: A persistent storage device includes a filesystem having a data exclusion list and a protection system stored thereon. The data exclusions list identifies excluded filesystem folders. A processor is programmed to create a canary file in at least one of the excluded filesystem folders. The processor intercepts input/output (I/O) events, each being directed to a respective target filesystem object. The processor stores system event metadata associated with each of the I/O events. The system event metadata includes a file identifier of the respective target filesystem object. The processor creates a backup copy for each respective target filesystem object. The processor releases the I/O events to be performed on the respective target filesystem objects. In addition, the processor determines, based on at least one file identifier, that one of the respective target filesystem objects is the canary file, and replaces each respective target filesystem object with its respective backup copy.

Abstract: Disclosed are systems and methods for providing virtual reality guidance to a user performing a procedure on a virtual instance of an item. The systems and methods may be used in training the user to perform the procedure on a physical instance of the item.
