Embodiment Construction

[0015] Below with the accompanying drawings ( figure 1 ) to illustrate the present invention.

[0016] figure 1 It is a schematic structural diagram of a system implementing the recovery of user partitions for shared smart devices in accordance with the present invention. Such as figure 1 As shown, by adding the middle layer of the AUFS system on top of the file system such as EXT4, a unified packaging is performed on the underlying file system. All top-level file operations (VFS virtual file system) will be processed through the AUFS layer first, and the AUFS layer determines how the file should be read and written. This ensures that all file operations are controlled by the AUFS layer.

[0017] The recovery operation stage includes that when the system needs to restore the data of the user partition, it will send an instruction to restore the partition to the bottom layer. After receiving the instruction, the bottom layer will write the corresponding mark to a certain lo...

Abstract

The invention discloses a system and a method for realizing user partition recovery for shared intelligent equipment, is favorable for removing private data left after a previous users uses a user partition so as to recover the user partition, can prevent data preset by the system from being damaged and can avoid chip damage or service life shortening caused in a way that a user partition flash chip is frequently subjected to an erasing operation. In addition, the user data clearing speed of the method are superior to traditional restore factory settings. The system for realizing the user partition recovery for the shared intelligent equipment comprises an AUFS (Another UnionFS) file system, wherein the AUFS file system is positioned between a bottom layer file system and a top layer virtual file system, and the top layer virtual file is connected with the bottom layer file system through the AUFS file system.

Description

technical field [0001] The present invention relates to the control or processing technology of user partitions in smart devices, that is, data partitions or user data file partitions, in particular a system and method for restoring user partitions to shared smart devices, which is beneficial to both clearing the user partitions used by previous users. The private data left behind can be restored to the user partition, and the pre-set data of the system can not be destroyed, and the chip damage or life shortening caused by frequent erasing operations on the user partition can be avoided. Background technique [0002] With regard to the idea of ​​sharing smart devices, the inventors found that for sharing smart devices, such as sharing mobile phones, it often involves different people using the same smart phone successively, and each person will always leave a user partition in the mobile phone during use. There is no need to keep these private data in the mobile phone, and e...
