Referring to fig. 2, a schematic diagram of program modules of the application backup system in the electronic device 1 is shown. The application backup system 20 includes, but is not limited to, a determination module 21, a recovery module 22, a backup module 23, and an interface module 24. It should be noted that the modules described herein are a set of program instructions stored in the memory 11 for implementing specific functions.
The memory 11 stores a system file of the electronic device 1 and an application file installed in the electronic device 1. In this embodiment, the memory 11 is a flash memory. Different storage partitions are defined in the memory 11, and the system files and the application files are stored in the different storage partitions of the memory 11, that is, the storage paths of the system files and the application files are different. In this embodiment, different backup partitions are defined in the memory 11, such as a system backup area for storing system backup files and an application backup area for storing application backup files. The different storage partitions and the different backup partitions are different areas of the memory 11 that are logically independent of each other.
Referring to fig. 3, a storage example of an application backup area in an embodiment of the present invention is shown. The application backup area of the memory 11 is defined with a header information area, an application program area, and a free area. The free area is an area which is not stored with any data information temporarily in the application backup area. When the storage block storing the data in the application backup area is damaged, the data stored in the storage block can be stored in the free area, so that the data loss is avoided. In the embodiment, considering the problem of bad blocks in the flash memory and the size of the backup file, the size of the free area in the application backup area should not exceed 15% of the application backup area. And a backup application program file is stored in the application program area.
The header information area stores basic information of each backup application, a storage address of the backup application, and a check value of the header information. The check value is used for verifying the data information of the application backup area; the storage address of the backup application program is a logical address stored in the application backup area when the application program is backed up in the application backup area; the basic information of each backup application program comprises the number and/or name of the backed-up application program, the file size, the file path and other information. Referring to fig. 4, a storage example of each backed-up application in an embodiment of the present invention is shown. The application backup area stores basic information of each backed-up application program, including a backup number (i.e., Int Key) of the application program, a file Size (i.e., Int Back _ Size) of the application program, a file Path (i.e., Char App _ Path) of the application program, and a check value (i.e., unidimed IntCrc _ Byte) of file content. In this embodiment, the check value of the file content is the same as the check value of the header information. The program file path is a file path in the electronic device 1 when the application program runs on the electronic device 1. The check value is used for judging whether the file content of the application program is changed. In this embodiment, the backup module 23 backs up the system files and the application files of the electronic device 1 in the system backup area and the application backup area, respectively.
The backup module 23 specifically includes the following steps in backing up the application program file to the application backup area: firstly, selecting an application program to be backed up; then, the selected application program to be backed up is made into a mirror image file of the application program by using a mirror image program; and finally, backing up the image file of the application program to an application backup area of the memory by using a backup program.
In this embodiment, the selection of the application to be backed up is implemented by the interface module 24. In particular, the interface module 24 provides an interface that enables a user to select an application to be backed up. The interface includes a window or option for the user to select the application to be backed up. Referring to fig. 5, in an embodiment, the interface module 24 may read all the applications installed on the electronic device 1 from the application storage area of the memory 11, provide an option for each read application on the interface, and display the interface and the option and the name of the application to the user. The user can select the application program corresponding to the option to be backed up by clicking the option on the interface, that is, when the user clicks the option, the user indicates that the user selects to back up the application program, and the backup request of the reference program is triggered. As shown in fig. 5, the user has selected application 1, application 2, and application 4 as applications to be backed up. It will be appreciated that when the number of applications exceeds the real-world area of the interface, the applications may be displayed in a split-screen manner or a slider may be provided for the user to view other applications, and not to follow up. The window can receive input operation of a user and select an application program to be backed up according to information input by the user, for example, the application program to be backed up is selected according to an application program name input by the user. The application program to be backed up is any non-system program installed on the electronic device 1.
In the present embodiment, the backup program is a system-owned application program that is run on the electronic device 1 and is used to backup system files. Therefore, after the backup program makes the application program selected by the user and needing backup into the image file, the image file is merged into the version file of the system file. When the system file needs to be updated, namely version upgrade, the backup program will backup the image file of the application program to the application backup area. In this embodiment, the image file of the application is an img image file. In another embodiment, the backup program is an application program installed on the electronic device 1 and provided by a third party for program backup, such as a fastboot program.
The judging module 21 is configured to judge whether a system file of the electronic device 1 is recovered during a boot process of the electronic device 1. In this embodiment, the start-up of the electronic device 1 includes two modes; one of them is the normal starting mode of the system, and the other is the recovery starting mode of the system. When the electronic device 1 is powered on, if the electronic device 1 adopts the system recovery start mode, the determining module 21 determines that the system file of the electronic device 1 is recovered during the power on process.
When the system file of the electronic device 1 is restored, the determining module 21 further determines whether the application program is ready to be damaged. When the application program is damaged, the recovery module 22 acquires the backup file of the application program from the application backup area XX, and recovers the application program by using the acquired backup file.
In this embodiment, the determining module 21 determines whether the application program is ready for damage according to whether the two check values are consistent or not by acquiring the check value in the header information of the application program backup area and the check value in the file content of the application program. When the two check values are inconsistent, the determining module 21 determines that the application program has been damaged, and needs to perform backup recovery on the application program. When the two check values are consistent, the determining module 21 determines that the application program is not damaged in the system recovery process, so that the application program does not need to be backed up and recovered.
Therefore, the application program backup recovery method provided by the invention can perform backup recovery on the application program only when the system of the electronic equipment is recovered and the application program is detected to be damaged. Therefore, unnecessary recovery of the undamaged application program can be avoided, and data loss of the application program in the recovery process of the application program can be avoided.
In another embodiment of the present invention, after the application program selected by the backup module 23 is backed up in the application backup area, the determining module 21 may read the check value of the file content of the application program and the check value of the header information area of the application backup area, and determine whether the two check values are consistent. When the two check values are not consistent, the determining module 21 determines that the file backup of the application program is incorrect, i.e. needs to be backed up again, and sends information to the backup module 23. The backup module 23 reads the files in the directory specified by the application program from the electronic device 1 again and backs up the files until the two check values are consistent. When the two check values are consistent, the determining module 21 determines that the file backup of the application program is accurate. Therefore, the accuracy of the application program for backing up the file can be ensured.
In an embodiment of the present invention, the backing up the application program to the application backup area by the backup module 23 specifically includes the steps of: writing a backup mark of the selected application program into the free area before performing backup recovery on the application program; and after the application program backup is completed, clearing the backup mark from the free area. And when power failure occurs in the backup recovery process of the application program and the backup mark is read from the idle area, performing backup recovery on the application program again.
Therefore, the application program backup recovery method provided by the application can provide a power-off protection mechanism when the application program is backed up, namely, under the condition of power-off, whether the backup work of the application program is complete or not can be identified. If not, the backup can be carried out again to ensure the integrity of the application program.
In an embodiment of the present invention, the restoring, by the restoring module 22, the application program by using the read backup file includes: writing a backup mark of the selected application program into the free area before backup recovery is carried out on the application program; after the application program backup is completed, the backup mark is removed from the free area; and when power failure occurs in the backup recovery process of the application program and the backup mark is read from the idle area, performing backup recovery on the application program again.
Therefore, the application program backup and recovery method provided by the application program can provide a power-off protection mechanism when the application program is recovered, namely, whether the recovery work of the application program is complete or not can be identified under the condition of power-off. If not, the backup can be restored again to ensure the integrity of the backup restoration of the application program.
Referring to fig. 6, a flowchart illustrating steps of a method for restoring backup of an application according to an embodiment of the present invention is shown. In this embodiment, the execution order of the steps in the flowchart shown in fig. 6 may be changed and some steps may be omitted according to different requirements.
In one embodiment, in this embodiment, the startup of the electronic device 1 includes two modes; one of them is the normal starting mode of the system, and the other is the recovery starting mode of the system. When the electronic device 1 is powered on, if the electronic device 1 adopts the system recovery start mode, the determining module 21 determines that the system file of the electronic device 1 is recovered during the power on process.
In one embodiment, step 601 can be omitted, that is, the starting step 602 of the application backup recovery method includes: when the electronic equipment recovers the system file in the starting process, whether the application program on the electronic equipment is damaged or not is judged.
In an embodiment, the application backup area is defined with a header information area and an application program area, the header information area stores a check value of header information, and the check value is used for verifying data information of the application backup area; and a backup application program file is stored in the application program area. The header information also stores basic information of each backup application program, and the basic information of each backup application program comprises the file size of the application program, the file path of the application program and the check value of the file content of the application program.
Step 602 specifically includes: the judging module 21 judges whether the application program is ready for damage by acquiring the check value in the header information of the application program backup area and the check value in the file content of the application program, and according to whether the two check values are consistent. When the two check values are inconsistent, the determining module 21 determines that the application program has been damaged, and needs to perform backup recovery on the application program. When the two check values are consistent, the determining module 21 determines that the application program is not damaged in the system recovery process, so that the application program does not need to be backed up and recovered.
In this embodiment, the backup module 23 reads a backup file of the application program from the application backup area of the memory 11.
And step 604, restoring the application program by using the read backup file.
Specifically, the backup module 23 uses the backup program to restore the application program with the read backup file. In the present embodiment, the backup program is a system-owned application program that is run on the electronic device 1 and is used to backup system files. Therefore, after the backup program makes the application program selected by the user and needing backup into an image file, the image file is merged into the version file of the system file. When the system file needs to be updated, i.e. version upgrade, the backup program will backup the image file of the application program to the application backup area. In this embodiment, the image file of the application is an img image file. In another embodiment, the backup program is an application program installed on the electronic device 1 and provided by a third party for program backup, such as a fastboot program.
Therefore, the application program backup recovery method provided by the invention can perform backup recovery on the application program only when the system of the electronic equipment is recovered and the application program is detected to be damaged. Therefore, unnecessary recovery of the undamaged application program can be avoided, and data loss of the application program in the recovery process of the application program can be avoided.
In an embodiment of the present invention, the restoring, by the restoring module 22, the restoring the application program by using the read backup file specifically includes: writing a backup mark of the selected application program into the free area before performing backup recovery on the application program; after the application program backup is completed, the backup mark is removed from the free area; and when power failure occurs in the backup recovery process of the application program and the backup mark is read from the idle area, performing backup recovery on the application program again.
Therefore, the application program backup and recovery method provided by the application program can provide a power-off protection mechanism when the application program is recovered, namely, whether the recovery work of the application program is complete or not can be identified under the condition of power-off. If not, the backup can be restored again to ensure the integrity of the backup restoration of the application program.
In another embodiment, the application backup recovery method further includes, before step 601, the steps of: and backing up the application program files into the application backup area. Specifically, the step of backing up the application program file to the application backup area includes the following steps: firstly, selecting an application program to be backed up; then, the selected application program to be backed up is made into a mirror image file of the application program by using a mirror image program; and finally, backing up the image file of the application program to an application backup area of the memory by using a backup program.
In this embodiment, the selection of the application to be backed up is implemented by the interface module 24. In particular, the interface module 24 provides an interface that enables a user to select an application to be backed up. The interface includes a window or option for the user to select the application to be backed up. In one embodiment, the interface module 24 may read all the applications installed on the electronic device 1 from the application storage area of the memory 11, provide an option for each read application on the interface, and display the interface and the options and the names of the applications to the user. The user can select the application program corresponding to the option to be backed up by clicking the option on the interface, that is, when the user clicks the option, the user indicates that the user selects to back up the application program, and the backup request of the reference program is triggered. The window can receive input operation of a user and select an application program to be backed up according to information input by the user, for example, the application program to be backed up is selected according to an application program name input by the user. The application program to be backed up is any non-system program installed on the electronic device 1.
In an embodiment of the present invention, the backing up the application program file to the application backup area by the backup module 23 further includes: when an application program is backed up to the application backup area, the backup module reads the check value of the file content of the application program and the check value in the head information of the application backup area and judges whether the two check values are consistent. When the two check values are consistent, the backup module 23 determines that the file backup of the application program is correct; when the two check values are not consistent, the backup module 23 determines that the file backup of the application program is incorrect, and reads the file in the directory specified by the application program from the electronic device again and performs the backup until the two check values are consistent.
In another embodiment of the present invention, the backing up the application program to the application backup area further includes: writing a backup mark of the selected application program into the free area before the backup of the application program is carried out; and after the application program backup is finished, removing the backup mark from the idle area, and if the power failure occurs in the application program backup process and the backup mark is read from the idle area, carrying out backup on the application program again.
Therefore, the application program backup recovery method provided by the application can provide a power-off protection mechanism when the application program is backed up, namely, under the condition of power-off, whether the backup work of the application program is complete or not can be identified. If not, the backup can be carried out again to ensure the integrity of the application program.
