What Does Post-Processing Deduplication (PPD) Mean?

Post-process deduplication (PPD) refers to a system where software processes filter redundant data from a data set after it has been transferred to a data storage location. This can also be called asynchronous deduplication, and is often used where managers consider it inefficient or unfeasible to remove redundant data before or during transfer.
