8. The agent cloud platform of claim 7, wherein the catalog retrieval module comprises a request receiving unit and a catalog retrieval unit, wherein:
the request receiving unit is used for receiving a backup request sent by the proxy cloud client, wherein the backup request comprises a user identifier;
and the directory acquisition unit is used for acquiring user file directories corresponding to the user identifications from the plurality of cloud storage systems according to the user identifications.
9. The utility model provides a proxy cloud client that is used for file to pass each other between many cloud storage systems which characterized in that includes information receiving module and instruction sending module, wherein:
the information receiving module is used for receiving backup information appointed by a user, wherein the backup information comprises files or directories to be backed up, a target cloud storage system and a target storage path, and the files to be backed up appointed by the user exist in a plurality of cloud storage systems and a source cloud storage system is not appointed by the user;
the instruction sending module is used for sending a backup instruction to the proxy cloud platform after the information receiving module receives the backup information, so that the proxy cloud platform determines the priority of the plurality of cloud storage systems containing the files to be backed up, takes the cloud storage system with the highest priority among the plurality of cloud storage systems containing the files to be backed up as a source cloud storage system, downloads a source file from the source cloud storage system, stores the source file in a cache space distributed for the user, and uploads the downloaded files to a target directory of a target cloud storage system, wherein the priority is determined according to the network service quality of the plurality of cloud storage systems.
10. The agent cloud client of claim 9, further comprising a request sending module, a catalog receiving module, and a catalog presenting module, wherein:
the request sending module is used for sending a backup request of a user to the proxy cloud platform, wherein the backup request comprises a user identifier, so that the proxy cloud platform can acquire user file directories corresponding to the user identifier from a plurality of cloud storage systems according to the user identifier;
the directory receiving module is used for receiving the user file directory sent by the proxy cloud platform;
and the directory presentation module is used for presenting the user file directory to a user so that the user can inquire and specify the source cloud storage system and the file or directory to be backed up.
11. A system for file mutual transmission among multiple cloud storage systems, which is characterized by comprising the proxy cloud platform for file mutual transmission among multiple cloud storage systems according to any one of claims 6 to 8, and the proxy cloud client for file mutual transmission among multiple cloud storage systems according to claim 9 or 10.
