ABSTRACT:
A method of changing storage drive contents includes changing, in an operating system, a main storage driver to create a virtual storage driver, wherein the virtual storage driver redirects access requests to a main storage either to one of the main storage and a temporary storage; copying, as a background process, blocks from the main storage to the temporary storage; restoring, to the temporary storage as a background process, blocks from a source storage into blocks of the main storage that have already been copied; and redirecting, to the temporary storage, operating system's requests for access to blocks of the main storage that have been copied to the temporary storage. The method can also include hiding the temporary storage from the operating system. The main storage and the temporary storage can share partitions of the same physical storage drive. Free blocks of the physical storage drive can be used as blocks of the temporary storage. Blocks can be assigned to the temporary storage in succession.
