A first computational platform generates a data structure that indicates a set of blocks, wherein the indicated set of blocks have to be rewritten to revert a logical storage structure stored in the first computational platform to a previous state. An Input/Output (I/O) request that corresponds to a read operation on a selected block of the logical storage structure is received. A determination is made from the data structure that the selected block has to be rewritten to revert the logical storage structure stored in the first computational platform to the previous state. The first computational platform receives the selected block from a second computational platform, in response to a request made by the first computational platform to the second computational platform for the selected block.
