description Multiple target blocks are allocated on a first storage device to store a target object. The target blocks are arranged to be in a one-to-one correspondence with multiple source blocks of a source object. The target blocks are set to a non-populated state, and target blocks in the non-populated state are populated with data from corresponding source blocks. While the target blocks are being populated, if a request is received to retrieve data from one of the target blocks that is in the non-populated state, then the one of the target blocks is populated with the data from the corresponding source block and set to a populated state.
