Method and system for fusing private cloud storage

The invention belongs to the field of communication, and provides a method and system for fusing private cloud storage. The method comprises the steps that a DS-C automatically finds and pairs a DS-S, an HBC reports heartbeat data to a CSM at fixed period, the CSM writes updated heartbeat data in a DB, an MFS monitors the file changes of Media Files, the MFS informs an MFP to carry out file analysis when the files of the Media Files are changed, the MFP analyzes changed files on the Media Files to obtain the metadata of the changed files, the MFP forwards the obtained metadata to a PCS, the PCS uploads the obtained metadata to an MIC, an MID compares the metadata received by the MIC with the metadata on the DB, and the MID writes the metadata received by the MIC in the DB when the metadata received by the MIC are different from the metadata on the DB. The method and system for fusing the private cloud storage saves the time of a user for storing or moving the files.
