(2) this ordinary file is connected on loop equipment;
(3) loop equipment is formatd.
And described step 2 mobile terminal by the concrete steps of block device access mode access cloud storage system is:
(1) mobile terminal connects this loop equipment by wireless network;
(2) Loop device loads is under the catalogue of mobile terminal appointment;
(3) under assigned catalogue, create a file;
(4) by the editing machine of mobile terminal, realize creating the access of file;
(5) piece level mode file reads and upgrades.
And, described step (5) piece level mode file read and renewal comprises the following steps:
1. mobile terminal connects corresponding dummy block will equipment in block device mode;
2. mobile terminal reads corresponding document specified data block in dummy block will equipment in internal memory;
3. mobile terminal is write the partial data piece of renewal in internal memory, and the memory block that mark is corresponding is dirty data piece;
4. mobile terminal writes dirty data piece in dummy block will equipment.
And the concrete steps that described step 2 mobile terminal is accessed cloud storage system by file access mode are:
(1) HTTP file server is connected on this loop equipment by network;
(2) Loop device loads is under the catalogue of the appointment of HTTP file server;
(3) by the HTTP uploading tools of mobile terminal, under HTTP file server assigned catalogue, upload a file;
(4) by the browser of mobile terminal, realize the access to upload file.
Advantage of the present invention and good effect are:
1, the present invention uses the virtual block device (being similar to hard disk) that becomes of ordinary file by loop equipment, by adopting dummy block will equipment and technology, the All Files of a mobile terminal is all put in a dummy block will equipment container, both avoid the exponential growth of quantity of documents, realized again the isolation of file between mobile terminal.
2, patent of the present invention creates the file system (as EXT4, HFS etc.) of supporting large file according to user's actual needs, and for example Android platform is supported maximum 16TB(16*1024GB) file; IOS platform is supported maximum 1EB(1024*1024*1024) file read-write.
3, the present invention supports the specified portions of user's file reading from cloud storage system and only by the data back cloud storage system of change, has reduced user network flow, has improved user's access efficiency.
4, the present invention is reasonable in design, usings " dummy block will equipment " as user file storage container, has avoided the exponential growth of quantity of documents, has improved the performance of cloud storage system; Meanwhile, provide piece level read and upgrade, reduced user network flow, improved user's access efficiency.

Embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is further described.
A kind of cloud Realization of Storing of facing moving terminal, as shown in Figure 1, by loop equipment, the virtual block device (being similar to hard disk) that becomes of ordinary file is used, by adopting dummy block will equipment and technology, the All Files of a mobile terminal is all put in a dummy block will equipment container.Described loop equipment is a virtual device interface in mobile terminal document system, for shielding the direct access of user to physical file.Mobile terminal loads dummy block will equipment, and is regarded as local hard drive, when file reading, can be from cloud storage system reading section data block; And change is during file, first the data of change write to the internal memory of mobile terminal and be labeled as dirty data piece, then only dirty data piece is passed back in cloud storage system.
Mobile terminal accessing cloud storage system can be adopted in two ways, and as shown in Figure 2, a kind of mode is that the mode that mobile terminal passes through block device is accessed cloud storage system, and another kind of mode is that mobile terminal is accessed cloud storage system by file access mode.Specifically comprise the following steps:
