Claim Text:
1. A method for comparing data units, the method comprising: generating a first digest representing a first data unit stored in a first memory, by a first processor associated with the first memory; deriving a first encoded value based, at least in part, on the first digest and a predetermined value, by the first processor; generating a second digest representing a second data unit stored in a second memory different from the first memory, by a second processor different from the first processor, the second processor being associated with the second memory; deriving a second encoded value based, at least in part, on the second digest and the predetermined value, by the second processor; determining whether the first data unit and the second data unit are the same by comparing the first encoded value to the second encoded value; and if the second data unit is not the same as the first data unit, storing the first data unit in the second memory, by the second processor.
