Embodiment Construction
[0041] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0042] A mobile terminal-oriented cloud storage implementation method, as shown in Figure 1, uses a loop device to virtualize a common file into a block device (similar to a hard disk), and uses virtual block device technology to store all files in a mobile terminal into a virtual block device container. The loop device is a virtual device interface in the file system of the mobile terminal, and is used to shield users from direct access to physical files. The mobile terminal loads the virtual block device and treats it as a local hard disk. When reading a file, it can read some data blocks from the cloud storage system; when changing a file, first write the changed data into the memory of the mobile terminal and save it. Mark as dirty data blocks, and then only transfer dirty data blocks back to the cloud storage system.
