Detailed Description
For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present application based on the embodiments herein.
Referring to fig. 1, fig. 1 is a flow chart of a data recovery method according to an embodiment of the present application. As shown in fig. 1, the data recovery method may include the steps of:
and 101, under the condition that the data recovery triggering condition is met, sequentially detecting a plurality of backup data in the backup data area, wherein the plurality of backup data are obtained by backing up a plurality of original data in the main data area.
Specifically, the main data area refers to an NVRAM area of the communication module. The main data area may be used for storing a plurality of original data that needs to be used by the communication module during the startup process, where the plurality of original data may include, but is not limited to, calibration data, international mobile equipment identification (International Mobile Equipment Identity, abbreviated as IMEI), serial Number (SN), and the like. The backup data area may be any area of the communication module other than the main data area. The backup data area may be used for storing a plurality of backup data corresponding to a plurality of original data, such as backup data corresponding to calibration data, backup data corresponding to an international mobile equipment identification code, backup data corresponding to a product serial number, and the like.
Step 102, detecting a state of original data corresponding to the abnormal backup data in the main data area when detecting that the abnormal backup data exists in the plurality of backup data.
In this step, when detecting that there is abnormal backup data in the plurality of backup data in the backup data area, the state of the original data corresponding to the abnormal backup data in the main data area may be detected, and if detecting that the state of the original data corresponding to the abnormal backup data in the main data area is a normal state, step 103 is executed; if the state of the original data corresponding to the abnormal backup data in the main data area is detected to be the abnormal state, ending the data recovery flow.
And 103, when detecting that the state of the original data corresponding to the abnormal backup data in the main data area is normal, recovering the abnormal backup data by using the original data corresponding to the abnormal backup data.
In this step, if it is detected that the state of the original data corresponding to the abnormal backup data in the main data area is a normal state, the abnormal backup data may be restored using the original data corresponding to the abnormal backup data. Therefore, the original abnormal backup data in the backup data area can be restored to be normal, and the original data in the main data area can be restored conveniently by using the backup data after the normal backup data in the backup data area is restored later.
And 104, recovering the plurality of original data by utilizing the recovered plurality of backup data.
In this step, after the original abnormal backup data in the backup data area is restored, the original data in the main data area may be restored by using the backup data after the normal restoration in the backup data area.
In this embodiment, bidirectional data recovery can be performed on the main data area and the backup data area, so that when abnormal backup data exists in the backup data area, normal original data corresponding to the abnormal backup data in the main data area can be utilized to perform data recovery on the abnormal backup data, thereby ensuring that a plurality of backup data in the backup data area are kept normal, and further ensuring that data in the backup data area can perform data recovery on data in the main data area. Therefore, the probability of successful data backup and restoration can be improved, and the service performance of the communication module is more stable.
Further, the plurality of raw data includes calibration data, an international mobile equipment identification code, and a product serial number;
step 101, detecting a plurality of backup data in the backup data area sequentially includes:
and detecting the backup data corresponding to the calibration data, the backup data corresponding to the product serial number and the backup data corresponding to the international mobile equipment identification code in the backup data area in sequence.
In one embodiment, the plurality of raw data in the primary data region may include calibration data, an international mobile equipment identification code, and a product serial number. In this way, when detecting a plurality of backup data in the backup data area, it is necessary to sequentially detect the backup data corresponding to the calibration data in the backup data area, the backup data corresponding to the product serial number, and the backup data corresponding to the international mobile equipment identification code. If any one or more of the backup data are detected to be abnormal, the abnormal backup data are considered to exist; if all of the backup data are detected to be normal, it is considered that no abnormal backup data exist. By the method, the detection of the plurality of backup data in the backup data area can be realized, so that the plurality of backup data in the backup data area are ensured to be in a normal state.
Further, the abnormal backup data includes at least one of backup data corresponding to the calibration data, backup data corresponding to the international mobile equipment identification code, and backup data corresponding to the product serial number.
In an embodiment, since the plurality of original data in the main data area may include calibration data, an international mobile equipment identification code, and a product serial number, the plurality of backup data in the backup data area may include backup data corresponding to the calibration data, backup data corresponding to the international mobile equipment identification code, and backup data corresponding to the product serial number. That is, the abnormal backup data in the backup data area may be one or more of the backup data corresponding to the calibration data, the backup data corresponding to the international mobile equipment identification code, and the backup data corresponding to the product serial number, which is not specifically limited in the embodiment of the present application. When the number of the abnormal backup data is multiple, the data recovery is required for the multiple abnormal backup data, and if all the multiple abnormal backup data can be recovered to be normal, the original data in the main data area can be recovered by using the backup data after the normal recovery in the backup data area. If the plurality of abnormal backup data portions are restored to normal, the original data in the main data area cannot be restored by using the backup data in the backup data area.
Further, after detecting the state of the original data corresponding to the abnormal backup data in the main data area in sequence in step 102, the method further includes:
and when detecting that the state of the original data corresponding to the abnormal backup data in the main data area is an abnormal state, ending the data recovery flow.
In an embodiment, when detecting that the state of the original data corresponding to the abnormal backup data in the main data area is an abnormal state, the original data corresponding to the abnormal backup data cannot restore the abnormal backup data, and at this time, the data restoring process can be ended, and detection and judgment of other backup restoring files are not performed, so that the communication module is prevented from being always stopped in the link of the data restoring process in the starting process.
Further, after detecting the plurality of backup data in the backup data area in sequence in step 101, the method further includes:
and under the condition that each backup data in the plurality of backup data is detected to be normal, the plurality of original data is directly restored by utilizing the plurality of backup data.
In an embodiment, after detecting the plurality of backup data in the backup data area, if each backup data in the plurality of backup data is detected to be normal, the plurality of original data can be directly recovered by using the plurality of backup data, thereby improving the data recovery efficiency.
Further, before detecting the plurality of backup data in the backup data area in step 101, the method further includes:
detecting whether target files in a main data area exist or not, wherein the target files in the main data area and the target files in a backup data area are preset, and the target files in the main data area are used for reflecting whether a plurality of original data in the main data area exist abnormal original data or not;
under the condition that the absence of the target file in the main data area is detected, determining that the data recovery triggering condition is currently met;
under the condition that the existence of the target file in the main data area is detected, sequentially detecting a plurality of original data in the main data area;
if the plurality of original data are abnormal, deleting the target file in the main data area, and restarting the target file so as to enable the restarting target file to meet the data recovery triggering condition;
if the plurality of original data are not abnormal, the starting-up process is directly entered.
In an embodiment, before detecting the plurality of backup data in the backup data area, it is further required to determine whether a data recovery trigger condition is currently satisfied, so that it is required to detect the target file in the main data area, and determine whether the target file in the main data area exists. If the target file in the main data area does not exist, the condition that the original data in the main data area is abnormal and the data recovery is needed is indicated, namely that the current meeting of the data recovery triggering condition can be determined, and the data recovery flow is executed subsequently; if the target file in the main data area exists, detecting a plurality of original data in the main data area in sequence, if abnormality exists in the plurality of original data, deleting the target file in the main data area, restarting, and then meeting the triggering condition of data recovery after restarting, and executing the data recovery flow subsequently. If the plurality of original data in the main data area are normal, the data recovery is not needed, and the starting-up process is directly carried out.
By the mode, the communication module can determine whether to trigger the data recovery flow according to the target file in the main data area, namely, when a plurality of original data in the main data area have abnormal original data, the data recovery flow is actively triggered, and data recovery is carried out on the abnormal original data.
Further, the method further comprises:
and under the condition that the recovered plurality of backup data are utilized to recover the plurality of original data, recovering the target files in the main data area by utilizing the target files in the backup data area.
In an embodiment, the target file in the main data area is deleted before the data recovery process is triggered, so that when the recovered multiple backup data are used for recovering multiple original data, the target file in the main data area can be recovered by using the target file in the backup data area, and when the original data in the main data area are recovered, the target file in the main data area can be recovered, and the communication module can conveniently judge the state of the original data in the main data area in the next starting process.
In one embodiment, the data recovery process is shown in fig. 2, and may specifically include the following steps:
step 201, starting a communication module.
It should be noted that, when the communication module is calibrated before leaving the factory, the BACKUP and restore function of the communication module needs to be started by a tool, and calibration Data, an international mobile equipment identification code, a product serial number, and a target file (such as a restoeflag flag file) are respectively stored in two areas, namely an NVRAM-Data area (corresponding to the main Data area above) and a BACKUP-Data area (corresponding to the BACKUP Data area above).
Step 202, judging whether a RestoreFlag flag bit file exists in the NVRAM-Data area.
After the communication module is started, it is first required to detect whether a RestoreFlag flag bit file exists in the NVRAM-Data area, and if so, step 203 is executed; if the RestoreFlag flag bit file does not exist within the NVRAM-Data area, step 206 is performed.
Step 203, traversing all files within the NVRAM-Data area (i.e., the plurality of files corresponding to the plurality of original Data above).
Specifically, calibration Data in NVRAM-Data needs to be detected, and its deposition path may be: /mnt/vendor/nvdata/md/NVRAM/CALIBRAT/;
there is also a need to detect international mobile equipment identities in NVRAM-Data, which deposit paths may be: /mnt/vendor/nvdata/md/NVRAM/IMEI/;
there is also a need to detect a product serial number in NVRAM-Data, which can be deposited on the path: N/mnt/vendor/nvdata/md/NVRAM/SN/;
step 204, determining whether all files in the NVRAM-Data area cannot be opened.
If all files within the NVRAM-Data area can be opened normally, then step 205 is performed; if there is a file in the NVRAM-Data area that cannot be opened normally, then step 218 is performed.
Step 205, entering a startup procedure.
Step 206, triggering a restoration mechanism.
Step 207, traversing all files in the BACKUP-Data area.
Step 208, it is determined whether the calibration Data file in the BACKUP-Data area cannot be opened.
If the calibration Data file in the BACKUP-Data area cannot be opened, step 212 is performed; if the calibration Data file in the BACKUP-Data area can be opened, step 209 is performed;
step 209, determining whether the international mobile equipment identity file in the BACKUP-Data area cannot be opened.
If the International Mobile Equipment identity document in the BACKUP-Data region cannot be opened, step 214 is performed; if the International Mobile Equipment identity file in the BACKUP-Data region can be opened, step 210 is performed;
step 210, judging whether the product serial number file in the BACKUP-Data area cannot be opened.
If the product serial number file in the BACKUP-Data area cannot be opened, then step 216 is performed; if the product serial number file in the BACKUP-Data area can be opened, step 211 is performed;
step 211, cover NVRAM-Data area with all files in BACKUP-Data area.
Step 212, determine if the calibration Data file within the NVRAM-Data area cannot be opened.
If the calibration Data file within the NVRAM-Data area cannot be opened, then step 205 is performed; if the calibration Data file within the NVRAM-Data area can be opened, then step 213 is performed;
step 213, overwrite the calibration Data file in the BACKUP-Data area with the calibration Data file in the NVRAM-Data area.
Step 214, determining whether the international mobile equipment identity file in the NVRAM-Data area cannot be opened.
If the International Mobile Equipment identity file in the NVRAM-Data area cannot be opened, then step 205 is performed; if the International Mobile Equipment identity file within the NVRAM-Data area can be opened, then step 215 is performed;
step 215, using the international mobile equipment identity file in the NVRAM-Data area to overwrite the international mobile equipment identity file in the BACKUP-Data area.
Step 216, determine whether the product serial number file in the NVRAM-Data area cannot be opened.
If the product serial number file within the NVRAM-Data area cannot be opened, then step 205 is performed; if the product sequence number file within the NVRAM-Data area can be opened, then step 217 is performed;
step 217, the product sequence number file in the BACKUP-Data area is overlaid with the product sequence number file in the NVRAM-Data area.
Step 218, determining whether the calibration Data file, the international mobile equipment identification code file, and/or the product serial number file belong to the NVRAM-Data area.
If the calibration Data file, the International Mobile Equipment identity file, and/or the product sequence number file belong to the NVRAM-Data area, step 219 is performed; if the calibration Data file, the International Mobile Equipment identity file, and/or the product sequence number file do not belong to the NVRAM-Data area, step 205 is performed.
Step 219, delete the RestoreFlag flag bit file in the NVRAM-Data area and restart the module.
Through the steps, when the communication module triggers the backup restoring mechanism, the states of the calibration Data file, the international mobile equipment identification code file and the product serial number file in the back_data area can be detected one by one, when a certain file abnormality is detected, the corresponding file in the NVRAM_data area is detected, and when the backup restoring file in the back_data area is abnormal, the corresponding normal file in the NVRAM_data area can be backed up to the back_data area, so that the backup restoring Data of the back_data area can be restored. And once detecting that a certain file cannot be normally opened in the BACK-up_data area and the NVRAM_data area, immediately ending the detection and judgment flow, and not detecting and judging abnormality of other backup restored files, thereby simplifying the backup restoring mechanism flow.
Through the steps, the following technical effects can be achieved: by detecting states of the calibration Data file, the international mobile equipment identification code file and the product serial number file in the BACK_data area one by one, when detecting that a certain file is abnormal, by detecting the corresponding file in the NVRAM_data area, when the backup restoring file in the BACK_data area is abnormal, the corresponding normal file in the NVRAM_data area can be backed up to the BACK_data area, backup restoring Data of the BACK_data area can be restored, the purpose of bidirectional backup restoring of the NVRAM_data area and the BACK_data area is achieved, and the success rate of backup restoring is improved.
For example: when the calibration Data file in the NVRAM_data area is normal, the international mobile equipment identification code file and the product serial number file are abnormal, a backup restoring mechanism is triggered, and if the calibration Data file in the BACK_data is abnormal, the international mobile equipment identification code file and the product serial number file are normal, the calibration Data file in the NVRAM_data area can be backed up and restored to the BACK_data area, so that the purpose of restoring the BACK_data area is achieved, and then all the file backups in the BACK_data are restored to the NVRAM_data area, so that the purpose of restoring the NVRAM_data area is achieved.
