1. A system comprising:

  • at least one storage device configured to store an incoming data, calculate a hash value for the incoming data, and store the hash value as meta data; and

    a server configured to provide the incoming data to the storage device, wherein, when a later-scheduled post-deduplication operation is to be performed, as part of the later-scheduled post-deduplication operation, the server reads the meta data from the storage device, determines whether the meta data is duplicate in a mapping table, and performs a deduplication process regarding the incoming data based on the determination result.
