The invention discloses a portable storage apparatus with duplicate deletion calculation and
processing functions. The apparatus comprises a data storage module, a
communication interface control module and a communication port power-getting module, wherein the data storage module comprises a calculation
processing module, a high-speed cache,
system firmware, a pointer
database and a
dynamic storage region allocation module; the data storage module performs
data connection and power supply connection with the
communication interface control module and the communication port power-getting module through data and power supply connection lines; and the
communication interface control module and the communication port power-getting module are connected with a protected computer through high-speed communication cables. The invention furthermore discloses a duplicate deletion calculation and
processing method and a data uploading method, which adopt the portable storage apparatus. The portable storage apparatus with the calculation capability is provided; the apparatus is exquisite, portable and passive, and is a storage and calculation integrated apparatus; and an
algorithm for performing pre-
copying or post-
copying deletion on duplicated
backup data runs in the apparatus, so that the
data transmission amount and the medium storage space of the
backup data are greatly reduced.
