In one embodiment, a method is provided. The method of this embodiment may include entering one mode of operation of first circuitry. In accordance with this one mode of operation, if an input/output (I/O) request is received by the first circuitry when the first circuitry is the one mode of operation, the first circuitry prevents the I/O request from being executed and stores the I/O request for future execution. The method of this embodiment may also include entering another mode of operation of the first circuitry. In this another mode of operation, the first circuitry may permit data stored in first storage associated with the first circuitry to be copied to second storage. The entry of the first circuitry into the another mode of operation may be based, at least in part, upon a determination by the first circuitry of whether second circuitry associated with third storage is ready to permit data stored in the third storage to be copied to the second storage. Of course, many variations, modifications, and alternatives are possible without departing from this embodiment.
