The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.
The scheme provided by the application can be used in a real scene that partial data in the terminal is restored after the terminal is restored to factory settings when people use the terminal in daily life, and for convenience of understanding, a few terms and application scenes related to the embodiment of the application are first briefly introduced below.
Recovery mode (Recovery mode): the backup function of an Android terminal refers to a mode that can modify data or an operating system inside the Android terminal.
Mounting: a process by which computer files and directories on a storage device (such as a hard disk, optical disk, or shared resource) are made available to a file system of a terminal device by an operating system.
And (4) factory setting restoration: the method includes that the terminal is restored to a default state when the terminal leaves a factory, for example, functions of a starting interface, a working mode, an operation shortcut key, a timing prompt and the like of the terminal are restored, and saved parameter settings, user data and the like are cleared. The method has the function of formatting various storage partitions (such as a formatted data (data) partition, a cache (cache) partition and the like) of the terminal.
Brushing the machine: the term "handset" refers to a handset that has some means of changing or replacing some language, picture, ring, software, or operating system that is originally present in the handset. Or, the refreshing is to reinstall the system for the mobile phone.
With the rapid development of science and technology, the use of the terminal greatly facilitates the daily life of people, and people can use the terminal to work, study, entertain and the like. The user can store the generated data in the terminal, for example, the user can store the information such as the photo taken by the user and the phone number of the friend in the terminal, so that the user can conveniently check the information. With the increase of the use times of the terminal, the data which the user may store in the terminal is more and more, and the performance of the terminal may be reduced by a large amount of stored data, so that the terminal is not smooth in operation and the like. Or, the user needs to restore factory settings to the terminal and clear data in the terminal. The user can work the terminal in the recovery mode to complete the clearing of the data in the terminal.
Referring to fig. 1, a schematic view of a scenario that a terminal provided by an exemplary embodiment of the present application operates in a recovery mode is shown. As shown in fig. 1, a terminal 100, a power control 101, and a volume control 102 are included.
Optionally, the terminal 110 is a terminal having a recovery mode. For example, the terminal may be a mobile phone, a tablet computer, an e-book reader, smart glasses, a smart watch, an MP3 player (Moving Picture Experts Group audio Layer III, motion Picture Experts Group audio Layer IV, motion Picture Experts Group audio Layer 4), an MP4 player, a notebook computer, a laptop computer, a desktop computer, and the like. Optionally, the power control 101 and the volume control 102 are physical controls or virtual controls.
The user may turn off or on the terminal 100 by pressing the power control 101 for a long time, and when the terminal 100 is turned off, the user may also press the power control 101 and the volume control 102 at the same time, so that the terminal enters the recovery state shown in fig. 1, and the data of the terminal is deleted in the recovery state. Alternatively, the terminal 100 may enter the recovery state shown in fig. 1 in other ways, which is not limited in this embodiment of the application.
Currently, in the recovery mode shown in fig. 1, the terminal does not support the function of restoring the deleted data. That is, data deleted by the terminal in the recovery mode cannot be restored by the user, and the user cannot select data to be deleted when the terminal deletes data in the recovery mode. When a user wants to retain part of data in the terminal, the terminal is caused to lose internal data and cannot restore the data, and the security of the data stored in the terminal is reduced.
In order to protect the data which the user wants to store and improve the safety of the data storage when the user deletes other data in the terminal, the application provides a solution, which can restore the data which the user wants to store and is deleted before when the terminal is in the recovery mode. Referring to fig. 2, a flowchart of a method for recovering data according to an exemplary embodiment of the present application is shown. The method may be applied to the scenario shown in fig. 1, which is executed by the terminal in the scenario. As shown in fig. 2, the data recovery method may include the following steps:
The first operating mode may be a normal operating mode of the terminal, that is, in a normal use process of the terminal, the terminal receives an instruction to recover target data of the terminal. The first storage partition may be any partition which is divided into disks in the terminal and can be mounted in the normal operation mode, and the second storage partition is a partition which is divided into partitions in the terminal and cannot be mounted in the normal operation mode. That is, the terminal cannot mount the second storage partition in the normal operating mode, and the user cannot view the content of the second storage partition in the normal operating mode, or store data in the second storage partition.
The second working mode may be a recovery mode of the terminal, in which the terminal may mount the first partition and the second storage partition, that is, the second storage partition has a right to be mounted in the recovery mode, and in other modes, the terminal may not mount the second storage partition.
And 203, storing the target data in the second storage partition to the first storage partition, wherein the target data is the data stored from the first storage partition to the second storage partition when the terminal is restored to the factory setting last time.
When the terminal restores factory settings and executes commands such as deletion, modification and management on data in each storage partition except the second storage partition in the terminal, the data in the first storage partition is stored in the second storage partition, and then the data is the target data. After the terminal executes the above steps 201 and 202, the terminal may restore the data stored in the second storage partition from the first storage partition to the first storage partition when the terminal restores the factory settings last time, so that the target data is restored in the restore mode.
In summary, when the terminal is in the first operating mode, an instruction for recovering the target data in the terminal is received; the first working mode is a working mode that the first storage partition is mounted and the second storage partition is not mounted; restarting the terminal, and entering a second working mode, wherein the second working mode is a working mode for mounting the first storage partition and the second storage partition; and storing the target data in the second storage partition to the first storage partition, wherein the target data is the data stored from the first storage partition to the second storage partition when the terminal is restored to factory settings last time. According to the method and the device, the terminal mounts the second storage partition which is not mounted in the first working mode under the second working mode, so that the terminal can restore the data stored in the second storage partition from the first storage partition when the terminal restores the factory settings in the second working mode for the last time, and the safety of target data storage when a user deletes other data is improved.
In a possible implementation manner, the scheme shown in fig. 2 is described by taking as an example that before the terminal receives an instruction to restore target data in the terminal, the terminal may first execute a command to restore factory settings, and store the target data from the first storage partition to the second storage partition.
Referring to fig. 3, a flowchart of a method for recovering data according to an exemplary embodiment of the present application is shown. The method may be applied to the scenario shown in fig. 1, which is executed by the terminal in the scenario. As shown in fig. 3, the data recovery method may include the following steps:
step 301, when the terminal is in the first working mode, receiving an instruction for executing factory reset.
The first working mode is a working mode that the first storage partition is mounted and the second storage partition is not mounted.
Optionally, the description of the first operating mode may refer to the description in step 201, and is not repeated here. The terminal may receive a command to restore factory settings in the first operating mode. For example, a user may trigger a factory reset instruction through a factory reset control in the setting interface, so that the terminal receives the factory reset instruction. Or, in a possible implementation manner, a shortcut button for factory reset may be further disposed in the terminal, and the user may click the shortcut button, or the terminal may receive an instruction for factory reset execution. Referring to fig. 4, an interface diagram of a setting interface according to an exemplary embodiment of the present application is shown. As shown in fig. 4, a factory reset control 401 is included in the setting interface 400, and a user may click the factory reset control 401, so that the terminal receives an instruction to execute factory reset.
Optionally, the first memory partition may be a memory area for storing user data when the terminal is in the first operating mode, for example, the first memory partition is a data partition in the terminal, and may store user data of a user in each application program; or, the first storage partition may also be a cache partition in the terminal, and may also store user data cached in the terminal. Optionally, the second memory partition is a partition in which the terminal cannot be mounted in the first operating mode. The second memory partition may be partitioned and set by a manufacturer of the terminal, for example, before the terminal leaves a factory, the manufacturer of the terminal may partition a memory partition in the terminal as the second memory partition, and the terminal may not be mounted with the partition in the first operation mode.
Step 302, the terminal is restarted and enters a second working mode.
The description of the second operating mode may also refer to the description in step 202, and is not repeated here. Optionally, after the terminal is restarted and enters the second working mode, the terminal may obtain a trigger instruction for entering the second working mode, check whether the trigger instruction is the instruction for restoring the factory setting, mount the second storage partition in the second working mode if the trigger instruction is the instruction for restoring the factory setting, and mount the second storage partition if the trigger instruction is not the instruction for restoring the factory setting.
Step 303, storing the target data in the first storage partition to the second storage partition, and deleting the data in the first storage partition.
In a possible implementation manner, the terminal may first store the target data of the first storage partition in the second storage partition, and then delete the target data and the remaining data in the first storage partition, that is, perform subsequent factory restoration. In a possible implementation manner, when the terminal performs factory reset, the terminal may delete the target data in the first storage partition, and store the target data in the first storage partition to the second storage partition. That is, the second storage partition may correspond to a recycle bin, and the target data deleted by the terminal from the first storage partition may be temporarily stored in the second storage partition. Or, the terminal may also backup the target data in the first storage partition to the second storage partition in advance, that is, before the terminal performs factory reset, the target data is stored in the second storage partition first, and then the data in the first storage partition is erased, so that factory reset is completed. The storage or deletion order of the target data is not limited in the embodiments of the present application.
Optionally, the target data in the first storage partition may be set in the terminal in advance by a manufacturer of the terminal, for example, when a certain terminal leaves a factory, the manufacturer sets data in a system folder "album" in the terminal as the target data in advance, and when a user stores some data in the album, and the terminal restores the factory setting, the terminal may back up the data in the album as the target data, that is, store the data in the album as the target data in the second storage partition from the first storage partition. Optionally, the system folder may also be "note", "phone", etc.
In a possible implementation manner, the terminal may further provide an interface for selecting target data in the first operating mode, please refer to fig. 5, which shows an interface schematic diagram of a data selection interface according to an exemplary embodiment of the present application. As shown in fig. 5, each folder directory 501 and a selection control 502 are included in the terminal interface 500, when the user selects and checks the selection control, the terminal may know that data in the folder directory selected by the user is target data, and when the terminal performs factory reset according to the above steps, the terminal may store the data in the folder directory selected by the user as the target data in the second storage partition from the first storage partition.
Optionally, when the target data is more and the storage space of the second storage partition is insufficient, the terminal may store the target data in an overlay manner. That is, when the target data has already occupied the space of the second storage partition, and the terminal needs to continue to store other target data in the second storage partition, at this time, the terminal may replace the target data stored in the second storage partition first, so as to continue to backup the target data.
In a possible implementation manner, before the terminal backs up the target data in the second storage partition, the terminal may further obtain user identity information logged in the terminal, and store the user identity information in the second storage partition, so that the user is authenticated when subsequently restoring the target data. Optionally, the user identity information 402 of the terminal is logged in the setting interface shown in fig. 4, and when the user clicks the factory resetting control, the terminal may obtain the user identity information.
In a possible implementation manner, the terminal may not log in any user information currently, and before the terminal backs up the target data in the second storage partition, the terminal may further obtain an authentication password input by the user in the terminal, and store the authentication password input by the user in the second storage partition, so that the authentication is performed when the user subsequently restores the target data. Referring to fig. 6, which shows an interface schematic diagram displayed after a user clicks a factory reset control according to an exemplary embodiment of the present application, as shown in fig. 6, a terminal interface 600 includes a password input box 601, a confirmation control 602, and a cancel control 603, the terminal prompts the user to input a verification password by displaying the password input box 601, when the user inputs a password in the password input box 601 and clicks the confirmation control 602, the terminal may perform a subsequent factory reset step, and before backing up target data in a second storage partition, the terminal may acquire the verification password input by the user in fig. 6 and store the verification password in the second storage partition.
Optionally, when the terminal deletes the target data in the first storage partition and stores the target data in the first storage partition in the second storage partition, the terminal may further encrypt the target data stored in the second storage partition, so as to improve the security of the target data storage.
And step 304, restarting the terminal and entering a first working mode.
Optionally, after backing up the target data, the terminal may continue to perform the step of restoring the factory settings, for example, continue to erase other data of the first storage partition, continue to erase data of other first storage partitions, and the like. And after the factory reset is finished, restarting again and entering a first working mode.
305, when the terminal is in a first working mode, receiving an instruction of restoring target data in the terminal; the first operating mode is an operating mode in which the first memory partition is mounted and the second memory partition is not mounted.
Optionally, the user may click a control for restoring the target data in the terminal, so that the terminal receives an instruction for restoring the target data in the terminal. Referring to fig. 7, an interface diagram of a setup interface according to an exemplary embodiment of the present application is shown. As shown in fig. 7, a restore target data control 701 is included in the setting interface 700, and a user may click the restore target data control 701, so that the terminal receives an instruction to execute the restore target data.
Step 306, when receiving the instruction of restoring the target data in the terminal, performing a first verification, where the first verification is used to verify whether the terminal has the authority to restore the target data.
When the terminal receives an instruction of restoring the target data in the terminal, the terminal can verify the authority of restoring the target data executed this time.
In a possible implementation manner, when the user identity information of the terminal logged in when the factory settings of the terminal are restored last time is stored in the second storage partition, the first verification is performed according to the user identity information. Optionally, when the terminal receives an instruction to restore target data in the terminal, the terminal may obtain user information that a setting interface in the terminal logs in currently, perform verification according to the user information and stored user identity information, if the user information and the stored user identity information are the same, the terminal is considered to pass the first verification, and if the user information and the stored user identity information are different, the terminal is considered to fail the first verification.
In a possible implementation manner, when the second storage partition stores the verification password set when the factory settings of the terminal are restored last time, the first verification is performed according to the verification password. Optionally, when the terminal receives an instruction to restore the target data in the terminal, the terminal may display a verification password input box in the terminal. Referring to fig. 8, an interface diagram of a terminal interface related to fig. 7 according to an exemplary embodiment of the present application is shown. When the user clicks the above-mentioned restore target data control in fig. 7, the terminal may present the interface shown in fig. 8, as shown in fig. 8, the terminal interface 800 includes a verification password input box 801, a confirmation control 802, and a cancel control 803. The user can input a password in the verification password input box 801 and click the confirmation control 802, the terminal can perform verification according to the password input by the user and the verification password stored in the second storage partition, if the password input by the user and the verification password are the same, the terminal is considered to pass the first verification, and if the password input by the user and the verification password are different, the terminal is considered to not pass the first verification.
Optionally, when the first verification fails N times, the target data is deleted from the second storage partition. Wherein N is an integer. Optionally, the terminal may set an upper limit of the verification times of the first verification, and if the first verification fails within N times, the terminal may delete the target data stored in the second storage partition, thereby preventing recovery of the target data in the second storage partition in other manners. Alternatively, N may be set in advance by the terminal manufacturer.
And 307, when the first verification is passed, restarting the terminal, and entering a second working mode, wherein the second working mode is a working mode for mounting the first storage partition and the second storage partition.
Optionally, when the first authentication of the terminal is passed, the terminal may enter the second operating mode by restarting.
In a possible implementation manner, the second storage partition stores a first storage time, and the terminal may first determine whether a second storage time, in which the target data is stored in the second partition, is less than the first storage time when entering the second operating mode in this step; and when the second storage time is less than the first storage time, executing the step of storing the target data in the second storage partition to the first storage partition.
For example, in a setting interface of the terminal, a user may set a storage duration of the target data in the second storage partition, please refer to fig. 9, which shows an interface schematic diagram of a setting interface according to an exemplary embodiment of the present application, as shown in fig. 9, a time input box 901, a confirmation control 902, and a cancellation control 903 are included in the setting interface 900, when the user inputs a duration that the target data needs to be stored in the time input box 901, and when the terminal performs factory reset, the terminal may also store the duration in the second storage partition. Therefore, before the terminal enters the second working mode to recover the target data, whether the duration of the target data in the second storage partition exceeds the duration input by the user can be judged, and when the duration of the target data in the second storage partition is smaller than the duration input by the user, the terminal executes the step of storing the target data in the second storage partition into the first storage partition.
Optionally, the storage duration of the target data in the second storage partition may also be set in advance by a manufacturer of the terminal, that is, the second storage partition in the terminal may store a default first storage time, and the acquisition of the first storage time is not limited in the embodiment of the present application.
In a possible implementation manner, when the second storage time is not less than the first storage time, the terminal may further delete the target data from the second storage partition. That is, if the terminal determines that the duration of the target data in the second memory partition exceeds the duration previously input by the user, the terminal may delete the target data from the second memory partition.
And 308, storing the target data in the second storage partition to the first storage partition, wherein the target data is the data stored from the first storage partition to the second storage partition when the terminal is restored to the factory setting last time.
Optionally, when the terminal stores the target data in the second storage partition into the first storage partition, the target data may be copied into a folder located at the last position in the original file directory according to the original file directory, where the original file directory is a file directory of the target data in the first storage partition when the terminal is last factory reset, and each original folder is a folder of a name of each folder included in the original file directory.
For example, when the terminal backs up the target data from the first storage partition to the second storage partition, the terminal may also store the folder directory of the target data in the second storage partition, and after the user recovers the target data, the user may find the target data according to the folder directory in which the original target data is located. For example, the folder directory stored by the terminal in the second memory partition may be: user: application one/recent files/albums. When the terminal stores the target data from the second storage partition to the first storage partition, the target data can be restored and stored according to the file directory. Optionally, when the terminal executes the factory reset, the folder, the latest folder, and the album folder of the first application program are all deleted, and in this step, the folder, the latest folder, and the album folder of the first application program may be re-established, and the target data is stored in the corresponding directory.
Optionally, if the terminal performs encryption processing on the target data when storing the target data in the second storage partition when the factory settings are restored, correspondingly, in this step, the terminal may also decrypt the target data to obtain decrypted target data, and then restore the target data to the first storage partition.
Step 309, restart the terminal again, enter the first working mode.
And the terminal can enter the first working mode again through restarting after restoring the target data in the second working mode, thereby normally using the terminal. The user can also check the target data before the factory setting is restored last time in the terminal through a series of operations.
In summary, when the terminal is in the first operating mode, an instruction for recovering the target data in the terminal is received; the first working mode is a working mode that the first storage partition is mounted and the second storage partition is not mounted; restarting the terminal, and entering a second working mode, wherein the second working mode is a working mode for mounting the first storage partition and the second storage partition; and storing the target data in the second storage partition to the first storage partition, wherein the target data is the data stored from the first storage partition to the second storage partition when the terminal is restored to factory settings last time. According to the method and the device, the terminal mounts the second storage partition which is not mounted in the first working mode under the second working mode, so that the terminal can restore the data stored in the second storage partition from the first storage partition when the terminal restores the factory settings in the second working mode for the last time, and the safety of target data storage when a user deletes other data is improved.
The data recovery method shown in fig. 2 and 3 is exemplified by taking an example that the terminal is a mobile phone, the target data is data in a file directory preset by a mobile phone manufacturer, and the second storage partition is also a storage partition which is divided by the mobile phone manufacturer in advance and is used for storing the target data. Referring to fig. 10, a flowchart of a method for recovering data according to an exemplary embodiment of the present application is shown. As shown in fig. 10, the data recovery method may include the following steps:
Wallpaper and backup target data can be set by a manufacturer, such as backup albums, short messages, notes and the like. If the data space of the partition is insufficient, the old data mode can be overwritten by the new data.
And step 1008, restarting the mobile phone after the factory reset is finished, wherein the second storage partition cannot be mounted when the mobile phone is normally started.
At step 1009, the user selects a control to restore the target data.
