Technical Field
The invention relates to the technical field of Android systems, in particular to a backup method for an Android system.
Background
In the embedded Android device, when the device encounters important file backup of some problem devices, but some network information of the device, information of Bluetooth, wifi or apk (such as WeChat) and the like are difficult to backup by users, the device cannot be used immediately after factory setting is restored, and the device needs to be manually configured, so that the backup function is needed under the condition.
Disclosure of Invention
The invention provides a method for backing up and recovering a system on the premise of not influencing the use of a user in order to overcome the defects of the technology.
The technical scheme adopted for overcoming the technical problems is as follows:
A backup method for an Android system, comprising:
S1, creating a backup partition in a storage space of an Android system, mounting the created backup partition to a fixed file node, creating a file under the file node, and completing the creation of a local backup partition;
S2, when the storage space of the Android system is insufficient, creating a backup partition in the external storage, mounting the created backup partition to a fixed file node, creating a file under the file node, and completing the creation of the external storage area;
s3, in the process of acquiring root rights, when the root rights are required to be backed up, acquiring all files and information selected by a user and then storing all the files and information into a local backup partition or an external storage area according to the selection of the user;
S4, in the process of acquiring the root permission, when the backup needs to be restored, reading out the stored files and information of the local backup partition or the external storage area selected by a user, and restoring the read files and information to the corresponding positions.
Further, in step S1, a clear partition which is not subjected to the recovery system is selected, and a backup partition is created by adopting a dynamic partition method.
Further, the fixed file node in step S1 is a restore file node.
Further, the data structure of the file created in step S1 is composed of a header for storing the offset of the index for storing the offset and length of each block and a content block for storing the content in the block.
Further, in step S2, the external storage is a usb disk.
Further, the data structure of the file created in step S2 is composed of a header for storing the offset of the index for storing the offset and length of each block and a content block for storing the content in the block.
Further, in step S3, all files and information are stored in the local backup partition or the external storage area according to the created data structure of the files.
Further, in step S4, the stored files and information in the local backup partition or the external storage area selected by the user are read according to the data structure of the corresponding files.
Further, in step S4, if the restored file and information are located in the local backup partition, the local backup partition is released after the file and information stored in the local backup partition are read out.
Further, setting a user selection interface in the Android system, wherein the user selection interface is used for listing all selectable backup items and backup positions.
The beneficial effects of the invention are as follows: the backup content can be selectively controlled, such as Ethernet information, bluetooth information, wifi information, and certain apk information. The location of the backup may be selected for control (u-disk or system free space). And creating a dynamic partition or adopting a path of the u disk, and extracting the content to be backed up to the newly created partition or the u disk. The self-built partition of the factory setting avoidance system is restored to restore the content, the function of reserving user information when factory setting is restored is provided, and the restoration system can be backed up on the premise of not affecting the use of users.

Detailed Description
The invention is further described with reference to fig. 1.
A backup method for an Android system, comprising:
S1, creating a backup partition in a storage space of the Android system, mounting the created backup partition to a fixed file node, creating a file under the file node, and completing the creation of the local backup partition.
S2, when the storage space of the Android system is insufficient, creating a backup partition in the external storage, mounting the created backup partition to a fixed file node, creating a file under the file node, and completing the creation of the external storage area.
S3, in the process of acquiring the root permission, when the backup is needed, acquiring all files and information selected by a user to be backed up, and then storing all the files and information into a local backup partition or an external storage area according to the selection of the user.
S4, in the process of acquiring the root permission, when the backup needs to be restored, reading out the stored files and information of the local backup partition or the external storage area selected by a user, and restoring the read files and information to the corresponding positions.
The method solves the problem that the prior art scheme cannot backup the system configuration and apk information, and provides the backup function when the Android device recovers factory settings.
In one embodiment of the present invention, in step S1, a clear partition that is not subject to recovery (recovery) is selected, and a backup partition is created by using a dynamic partition method.
In one embodiment of the present invention, the file node fixed in step S1 is a restore file node.
In one embodiment of the present invention, the data structure of the file created in step S1 is composed of a header for storing an index for storing an offset and a length of each block and a content block for storing contents in the block.
In one embodiment of the present invention, in step S2, the external storage is a usb disk.
In one embodiment of the present invention, the data structure of the file created in step S2 is composed of a header for storing an index for storing an offset and a length of each block and a content block for storing contents in the block.
In one embodiment of the present invention, all files and information in step S3 are stored in the local backup partition or the external storage area according to the data structure of the created file.
In one embodiment of the present invention, in step S4, the stored files and information in the local backup partition or the external storage area selected by the user are read according to the data structure of the corresponding files.
In one embodiment of the present invention, if the restored file and information are located in the local backup partition in step S4, the local backup partition is released after the file and information stored in the local backup partition are read out. By adopting a dynamic partition mode, the backup partition can be deleted after backup is restored.
In one embodiment of the invention, the method further comprises setting a user selection interface in the Android system, wherein the user selection interface is used for listing all selectable backup items and backup positions.
