The invention discloses a
multimedia file
cloud storage platform and a method for eliminating redundancy by using the
cloud storage platform, and belongs to the field of
information processing. The
multimedia file
cloud storage platform comprises a storage interface management subsystem, a cluster management subsystem and a
storage management subsystem, wherein the storage interface management subsystem is used for generating an operation instruction and used for communicating with the cluster management subsystem or the
storage management subsystem. The method for eliminating redundancy by using the cloud storage platform comprises the following steps: firstly, calculating
fingerprint information of an uploaded file, generating a
verification instruction, transmitting the
verification instruction to the cluster management subsystem to be judged, if the
fingerprint information is available, checking a corresponding file
metadata instruction, and feeding back a result; or else verifying the
fingerprint information of the file, and transmitting a result; continuously judging whether the cloud storage platform has identical files or not, if the cloud storage platform has identical files, transmitting a redundancy
record adding instruction, and uploading a result; and if the cloud storage platform does not have identical files, storing the files, adding instructions, and uploading a result. By adopting the method, the storage load of a storage
server can be reduced, and
file transmission between a user and the cloud storage platform can be accelerated.
