S102, screening target parameter information from the parameter information of the target hard disk according to the use information of the target hard disk, wherein the use information of the target hard disk comprises the data volume stored in the target hard disk and/or the use duration of the target hard disk.
In the embodiment of the invention, since the parameter information of the target hard disk includes a plurality of parameter information, if the time of the failure of the target hard disk is predicted according to all the parameter information, the prediction efficiency is lower. In order to improve the prediction efficiency and the prediction precision, the parameter information in the target hard disk can be screened, specifically, the electronic equipment can screen the target parameter information from the parameter information of the target hard disk according to the use information of the target hard disk, wherein the target parameter information is part of the parameter information in the parameter information of the target hard disk. The use duration of the target hard disk is from the time when the electronic device corresponding to the target hard disk is activated to the current time, for example, the activation time of the electronic device is 2016, 11 and 23 days, and the current time is 2018, 11 and 23 days, so that the use duration of the target hard disk is 2 years.
S103, predicting the time of the failure of the target hard disk according to the target parameter information.
In the embodiment of the invention, the electronic equipment can predict the time of the failure of the target hard disk according to the target parameter information, and specifically, the electronic equipment stores the corresponding relation between each parameter information and the time of the failure of the hard disk, and determines the time of the failure of the target hard disk according to the corresponding relation.

The target hard disk may be used for 2 years according to the correspondence in table 1, and if the current time is 2018, 11, 23, the time when the target hard disk fails is 2020, 11, 23.

| 1 year-2 years | For 2 years |
| 2 years to 3 years | For 1 year |
And S104, backing up the data in the target hard disk to the standby hard disk before the system time reaches the time of failure of the target hard disk.
In the embodiment of the invention, in order to avoid data loss in the target hard disk, the electronic device can backup the data in the target hard disk to the spare hard disk before the system time reaches the time of the failure of the target hard disk. Specifically, the electronic device may backup the data in the target hard disk to the spare hard disk within one month or one week before the system time reaches the time when the target hard disk fails, or the like. For example, when the current time is 2018, 11 and 23 days and the failure time of the target hard disk is 2020, 11 and 23 days, the electronic device may backup the data in the target hard disk to the spare hard disk when the system time reaches 2020, 9 and 23 days.
The spare hard disk and the target hard disk may be hard disks located in the same electronic device, or may be hard disks located in different electronic devices.
In one example, the spare hard disk and the target hard disk may be hard disks located in different electronic devices, where the spare hard disk may include a co-city spare hard disk and a cross-city spare hard disk, where the co-city spare hard disk is a hard disk disposed in the same area as the target hard disk, and the cross-city spare hard disk is a hard disk disposed in a different area from the target hard disk. The electronic device can select a target spare hard disk according to the states of the same-city spare hard disk and the cross-city spare hard disk, wherein the states comprise a fault state and a normal state, and the data in the target hard disk is backed up to the target spare hard disk before the system time reaches the time when the target hard disk breaks down. For example, in order to reduce the workload of data migration and improve the efficiency of data migration, the data in the target hard disk may be preferentially stored in the spare hard disk in the same city; the electronic equipment can acquire the state of the standby hard disk in the same city, and if the state of the standby hard disk in the same city is in a normal state, the data in the target hard disk is backed up to the standby hard disk in the same city before the system time reaches the time when the target hard disk fails; if the state of the backup hard disk in the same city is a fault state, before the system time reaches the time when the target hard disk fails, the data in the target hard disk is backed up to the backup hard disk in a cross city.
In another embodiment, to equalize the storage pressure of each spare hard disk, the electronic device may select the target spare hard disk according to the amount of data stored by the same-city spare hard disk and the cross-city spare hard disk. For example, the electronic device may obtain the current data amount of the backup hard disk in the same city and the current data amount of the backup hard disk in a cross-city, take the backup hard disk with the smallest current data amount as the target backup hard disk, and backup the data in the target hard disk to the target backup hard disk before the system time reaches the time when the target hard disk fails.
In one embodiment, the electronic device may obtain states of the target hard disk in a plurality of time periods, where the states include an operating state and an idle state, determine a target time period in which the target hard disk is in the idle state, and store data in the target hard disk in the spare hard disk during the target time period before a time when the target hard disk fails.
In order to avoid influencing the normal operation of the service, the electronic device may backup the data in the target hard disk to the spare hard disk when the target hard disk is in an idle state. Specifically, the electronic device may obtain states of the target hard disk in a plurality of time periods, where the states include a working state and an idle state; the operating state refers to a state in which the amount of data written and/or data read by the target hard disk is relatively large, and the idle state refers to a state in which the amount of data written and/or data read by the target hard disk is relatively small. And determining a target time period of the idle state of the target hard disk, wherein the target time period is positioned before the time of the fault of the target hard disk, and storing the data in the target hard disk into the standby hard disk in the target time period.
In the embodiment of the invention, the electronic equipment can screen out the target parameter information from the parameter information of the target hard disk according to the use information of the target hard disk, and predict the time of the failure of the target hard disk by adopting the target parameter information; the method can avoid predicting the time of the failure of the target hard disk by adopting all the parameter information of the target hard disk, and only adopts the target parameter information to predict the time of the failure of the target hard disk, thereby improving the efficiency of predicting the failure of the target hard disk and improving the accuracy of predicting the failure of the target hard disk. Before the system time reaches the time when the target hard disk fails, the data of the target hard disk is backed up to the standby hard disk, so that the data loss in the target hard disk can be avoided, and the normal operation of the service is effectively ensured.
Fig. 2 is a schematic flow chart of another data processing method according to an embodiment of the present invention, where the method according to the embodiment of the present invention may be performed by the above-mentioned electronic device. In this embodiment, the data processing method includes the following steps.
S201, acquiring parameter information of a target hard disk, wherein the parameter information comprises the number of faults of a data block of the target hard disk, the number of errors of writing data into the target hard disk, the power-on duration of the target hard disk, the temperature information of the target hard disk and the voltage value of the target hard disk.
S202, screening target parameter information from the parameter information of the target hard disk according to the use information of the target hard disk.
In the embodiment of the present invention, the electronic device may screen out target parameter information from parameter information of the target hard disk according to the usage information of the target hard disk, and if the screened out target parameter information is the first type of target parameter information, execute step S203; otherwise, if the screened target parameter information is the second type of target parameter information, step S204 is executed.
The use information of the target hard disk comprises the data quantity stored in the target hard disk and/or the use duration of the target hard disk; the target parameter information comprises first-type target parameter information and second-type target parameter information, wherein the first-type target parameter information comprises one or more of the following items: the number of errors of writing data to the target hard disk, the power-on duration of the target hard disk and the number of faults of the data block of the target hard disk, and the second type of target parameter information comprises one or more of the following: and the temperature information of the target hard disk and the voltage value of the target hard disk.
In one embodiment, the usage information of the target hard disk includes an amount of data stored in the target hard disk, and step S202 includes: counting the data volume stored in the target hard disk, and screening the first type of target parameter information from the parameter information of the target hard disk if the data volume stored in the target hard disk is larger than the preset data volume; and if the data volume stored in the target hard disk is smaller than or equal to the preset data volume, screening the second type of target parameter information from the parameter information of the target hard disk.
The electronic equipment can screen the parameter information of the target hard disk according to the data volume stored in the target hard disk, specifically, if the data volume stored in the target hard disk is larger than the preset data volume, the number of times of writing data into the target hard disk is larger, the power-on duration of the target hard disk is longer, and the probability of failure of a data block is larger; therefore, the reference value of the failure time prediction of the target hard disk according to the first type of target reference information is higher, and the first type of target reference information is screened out from the reference information of the target hard disk. If the data volume stored in the target hard disk is smaller than or equal to the preset data volume, the number of times of writing data into the target hard disk is smaller, the power-on duration of the target hard disk is shorter, and the probability of failure of the data block is smaller; therefore, the reference value of the failure time prediction of the target hard disk according to the first type of target reference information is relatively low, and the second type of target reference information is screened out from the reference information of the target hard disk.
In another embodiment, the usage information of the target hard disk includes a usage duration of the target hard disk, and step S202 includes: acquiring running log data of the target hard disk, determining the using time length of the target hard disk according to the running log data of the target hard disk, and screening the first type of target parameter information from the parameter information of the target hard disk if the using time length of the target hard disk is longer than the preset time length; and if the using time length of the target hard disk is smaller than or equal to the preset time length, screening out the second type of target parameter information from the parameter information of the target hard disk.
The electronic equipment can screen the parameter information of the target hard disk according to the using time length of the target hard disk, specifically, the electronic equipment can acquire the running log data of the target hard disk, and determine the using time length of the target hard disk according to the running log data of the target hard disk, wherein the using time length of the target hard disk is the already used time length of the target hard disk. If the service time of the target hard disk is longer than the preset time, the number of times of writing data into the target hard disk is more, the power-on time of the target hard disk is longer, and the probability of occurrence of faults of the data block is larger; therefore, the reference value of the failure time prediction of the target hard disk according to the first type of target reference information is higher, and the first type of target reference information is screened out from the reference information of the target hard disk. If the using time length of the target hard disk is smaller than or equal to the preset time length, the number of times of writing data into the target hard disk is smaller, the power-on time length of the target hard disk is shorter, and the probability of occurrence of faults of the data blocks is smaller, so that the reference value of the fault time prediction of the target hard disk according to the first type of target reference information is lower; and in general, the temperature value of the temperature information of the target hard disk is approximately in direct proportion to the voltage value of the target hard disk, namely, the larger the temperature value is, the larger the voltage value is; the lower the temperature value, the lower the voltage value; when the relation between the temperature value of the temperature information of the target hard disk and the voltage value of the target hard disk does not have a direct proportion relation, the target hard disk is indicated to be in fault, so that the reference value of the fault time prediction of the target hard disk according to the second type of target reference information is higher, and the second type of target reference information can be screened out from the reference information of the target hard disk.
In another example, the electronic device may comprehensively consider the data amount stored in the target hard disk and the service life of the target hard disk to screen the parameter information of the target hard disk, so as to improve the accuracy of screening. Specifically, the electronic device may set weights for the data amount stored in the target hard disk and the usage time of the target hard disk, and perform weighted summation on the data amount stored in the target hard disk and the usage time of the target hard disk according to the weights to obtain a first value, and if the first value is greater than a preset value, the first type of target parameter information is screened out from the parameter information of the target hard disk; and if the first value is smaller than or equal to a preset value, screening the second type of target parameter information from the parameter information of the target hard disk. The weight of the data amount stored in the target hard disk and the use time setting weight of the target hard disk can be automatically set according to the requirement of a user.
S203, predicting the time of the failure of the target hard disk according to the first type of target parameter information.
In one embodiment, the first type of target parameter information includes the number of errors in writing data to the target hard disk, and step S203 includes: counting the total number of times of writing data into the target hard disk and the number of times of writing data into the target hard disk, determining the error rate of writing data into the target hard disk according to the number of times of writing data into the target hard disk and the total number of times of writing data into the target hard disk, and determining the time of failure of the target hard disk corresponding to the error rate of writing data into the target hard disk according to the corresponding relation between the error rate and the time of failure of the hard disk, wherein the corresponding relation between the error rate and the time of failure of the hard disk is determined according to the data of hard disk history failure.
The electronic device may predict a time at which the target hard disk failed based on a number of errors in writing data to the target hard disk. Specifically, the electronic device may count the total number of times of writing data into the target hard disk and the number of errors of writing data into the target hard disk according to the running log data of the target hard disk; determining the error rate of the data written to the target hard disk according to the error times of the data written to the target hard disk and the total times of the data written to the target hard disk, wherein generally, the higher the error rate of the target hard disk is, the more easily the target hard disk is broken down; the lower the error rate of the target hard disk, the longer the time to failure from the target hard disk. The electronic equipment can comprise a corresponding relation between the error rate and the time of the hard disk failure, wherein the corresponding relation is obtained by statistics according to the historical data of the hard disk failure; therefore, the electronic device can determine the time of the failure of the target hard disk corresponding to the error rate of the write data of the target hard disk according to the corresponding relation between the error rate and the time of the failure of the hard disk. For example, the correspondence between the error rate and the time when the hard disk fails may refer to the correspondence between the error rate interval and the time when the hard disk can be used, and as shown in table 2, when the error rate of the target hard disk [50%,60% ], the time when the target hard disk can be used is 2 years, the error rate of the target hard disk [60%,70% ], and the time when the target hard disk can be used is 1 year. If the total number of times of writing data into the target hard disk is 100 and the number of times of writing data into the target hard disk is 55, the error rate of writing data into the target hard disk is 55%, the duration that the target hard disk can be used is determined to be 2 years according to the corresponding relation in table 2, and if the current time is 2018, 11, 23 days, the time that the target hard disk fails is 2020, 11, 23 days.
TABLE 2
| Error rate | Usable time of hard disk |
| 50％-60％ | For 2 years |
| 60％-70％ | For 1 year |
In another embodiment, the first type of target parameter information includes a power-on duration of the target hard disk and a number of failures of data blocks of the target hard disk, and step S203 includes: calculating a first ratio between the power-on duration of the target hard disk and the number of failed data blocks of the target hard disk, determining the number of failed data blocks of the target hard disk according to the total number of the data blocks of the target hard disk and the number of failed data blocks of the target hard disk, and determining the time of the failed data blocks of the target hard disk according to the first ratio and the number of failed data blocks of the target hard disk.
The electronic equipment can predict the time of the failure of the target hard disk according to the power-on time of the target hard disk and the number of failures of the data blocks of the target hard disk. Specifically, the electronic device may calculate a first ratio between a power-on duration of the target hard disk and a number of failures of the data blocks of the target hard disk, where the first ratio is used to describe how many data blocks fail in a unit time (such as in a year). Determining the number of the data blocks of the target hard disk which do not have faults according to the total number of the data blocks of the target hard disk and the number of the data blocks of the target hard disk which have faults, and determining the time of the faults of the target hard disk according to the first ratio and the number of the data blocks of the target hard disk which do not have faults. The time of the faults of all the data blocks of the target hard disk is determined according to the number of the data blocks with faults and the number of the data blocks without faults in unit time, and the time of the faults of the target hard disk is predicted according to the time of the faults of all the data blocks of the target hard disk. Here, the failure of the target hard disk means that all the data blocks in the target hard disk fail. For example, when the target hard disk includes 1000 data blocks, 500 data blocks have faults, the power-on duration is 2 years, and the first ratio of the power-on duration to the number of faults of the data blocks is calculated to be 1/250, that is, 250 data blocks have faults on average each year; and if the current time is 2018, 11 months and 23 days, the time of the failure of the target hard disk is 2020, 11 months and 23 days after the time of the failure of all the data blocks of the target hard disk is 2 years according to the first ratio and the number of the data blocks without the failure.
In another embodiment, the first type of target parameter information includes the number of errors in writing data to the target hard disk, the power-on duration of the target hard disk, and the number of failures of the data block of the target hard disk; the electronic equipment can comprehensively consider all items in the first type of target parameter information to predict the time of the failure of the target hard disk, and accuracy of predicting the time of the failure of the target hard disk is improved. Specifically, determining the error rate of the data written to the target hard disk according to the number of errors of the data written to the target hard disk; calculating a first ratio between the power-on duration of the target hard disk and the number of faults of the data blocks of the target hard disk; and carrying out weighted summation on the error rate of the write data of the target hard disk and the first ratio to obtain a second numerical value, wherein the correspondence between the second numerical value and the time of the failure of the target hard disk is stored in the electronic equipment, and the time of the failure of the target hard disk can be determined according to the correspondence.
