A method of and system for protecting a disk drive or other data storage includes mounting a virtual storage that combines a READ-only portion of a volume of the main storage and a full access temporary storage located on the same data storage, wherein the READ-only portion represents a protected area of the volume of the main storage; generating a bitmap for blocks of the virtual storage; redirecting virtual storage write requests to the temporary storage; marking, in the bitmap, blocks of the virtual storage corresponding to blocks of the temporary storage that are being written to; redirecting, to the READ-only portion, read requests for unmarked blocks; redirecting, to the temporary storage, read requests for marked blocks; upon an acceptance of a state of the virtual storage, merging the temporary storage with unmarked blocks of the READ-only portion of the volume of the main storage, to form an integral storage; and upon a rejection of a state of the virtual storage, terminating the redirecting. Optionally, data in the temporary storage can be archived.
