Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
The existing terminal equipment, especially the traditional computer equipment, is often powered off maliciously in the using process, especially the computers for home office use, and the unexpected power off is often caused by various reasons in the using process, and data in the office process cannot be stored in time, so that the data are lost, and great inconvenience is brought to people. Therefore, the embodiment provides a data backup and recovery method, and through the method of the embodiment, the thorough data loss caused by system crash or equipment damage can be effectively avoided, sudden accidents are effectively prevented, and the data safety is guaranteed. In specific implementation, the present embodiment first obtains current input data, and determines a shutdown state according to the current input data. And backing up system data to an independent disk according to the shutdown state. And finally, when a starting command is received, acquiring a data recovery requirement, flashing the system data into a memory according to the data recovery requirement, and formatting the independent disk. The invention can save the system data in time and independently save the system data in the independent disk when the computer is shut down, can effectively avoid the complete data loss caused by system crash or equipment damage, can effectively backup and restore the system data and has high reliability.
For example, when a user uses a computer to work, the computer detects current input data in real time, and determines a power-off state according to the current input data, wherein the power-off state reflects whether the computer is normally powered off or abnormally powered off. Based on the determined shutdown state, the computer can save the system data at the moment in time. That is, when the computer is powered off, the computer automatically collects the system data, performs backup, and backs up the system data to an independent disk, so that the system data can be conveniently recovered and called when the computer is powered on subsequently. When the computer is started, the computer can obtain the data recovery requirement, namely, whether the data needs to be recovered is judged, if the data needs to be recovered, the system data in the independent disk can be flashed into the memory, and after the flashing, the independent disk can be formatted.
Exemplary method
In the data backup and recovery method in this embodiment, the data backup and recovery method may be applied to a terminal device, and the terminal device may be an intelligent product such as a computer, an intelligent television, a mobile phone, and the like. Specifically, as shown in fig. 1, the data backup and recovery method in this embodiment includes the steps of:
step S100, current input data are obtained, and a shutdown state is determined according to the current input data.
What this embodiment will realize is that can in time store system data when terminal equipment shuts down to prevent that terminal equipment from shutting down suddenly and causing the problem that system data loses. Therefore, in this embodiment, the terminal device needs to be monitored to determine whether the terminal device is powered off, and determine that the power off is normal, that is, determine the power off state. Therefore, the embodiment can acquire the current input data, the current input data is the power supply condition of the external power supply or the internal power supply for the terminal equipment, and the shutdown state can be determined according to the current input data.
In one implementation manner, when determining the shutdown state, the present embodiment includes the following steps:
s101, detecting the power supply current of an external power supply and an internal power supply through a detection end to obtain current input data;
step S102, when the current input data is empty, determining that the shutdown state is abnormal shutdown;
step S103, when the current input data is not empty, determining that the shutdown state is normal shutdown.
In specific implementation, the terminal device of this embodiment is preset with a detection end, and the detection end is used for detecting the power supply condition of the external power supply and the internal power supply of the terminal device to the terminal device, so as to obtain the current input data. In practical application, the detection end starts to detect the power supply current of the external power supply and the internal power supply when the terminal device starts a shutdown program, so that current input data can be acquired in time. When the detecting end normally detects the normal current input of the external power supply or the internal power supply, namely the current input data is not empty, the shutdown state is determined to be normal shutdown. And when the detection end does not normally detect the normal current input of the external power supply or the internal power supply, namely the current input data is empty, determining that the shutdown state is abnormal shutdown. In this embodiment, the shutdown state of the terminal device is determined, so that the system data of the terminal device is backed up according to the shutdown state.
And step S200, backing up system data to an independent disk according to the shutdown state.
When the shutdown state of the terminal device is determined, the embodiment can back up the system data according to the shutdown state, the purpose of the backup is to store the system data, and in order to conveniently back up the system data, an independent disk is arranged in the embodiment and is specially used for storing the system data. In this embodiment, the system data includes recorded data of the terminal device during use, such as log data, application use data, and data edited or input by the user (e.g., document input).
In an implementation manner, when backing up system data, the embodiment includes the following steps:
step S201, when the shutdown state is normal shutdown, acquiring a data backup requirement;
step S202, if the data backup requirement is that data backup needs to be performed, starting a preset capacitor power supply, and backing up the system data to the independent disk.
In specific implementation, the embodiment may determine whether the shutdown state of the terminal device is a normal shutdown or an abnormal shutdown, and execute different operations based on different shutdown states. When the shutdown state is normal shutdown, the detecting end detects normal current input, and at this time, the terminal device needs to determine whether system data needs to be backed up. Specifically, the terminal device may output a prompt message of a data backup requirement to inquire whether a backup is required at this time. When the user selects that data backup is needed, namely the data backup is needed, the data backup operation can be executed at the moment, and the system data can be backed up to the independent disk. In this embodiment, when performing a data backup operation, the present embodiment may start a predetermined capacitor power supply, which is to ensure that the system data can be successfully backed up. In another implementation manner, if the data backup requirement is that data backup is not needed (that is, a user selects that system data does not need to be backed up), the system is directly powered off.
In an implementation manner, if the shutdown state is abnormal shutdown, it indicates that the detecting end cannot detect normal current input, and it indicates unexpected shutdown, and in order to prevent data loss, the terminal device may automatically trigger a data backup operation to automatically backup the system data to the independent disk.
Step S300, when a starting command is received, acquiring a data recovery requirement, flashing the system data into a memory according to the data recovery requirement, and formatting the independent disk.
When the data backup is completed, the system data cannot be lost, and the terminal equipment can recover and call the system data in the next using process. When the terminal equipment is started, the data recovery requirement can be obtained, namely whether the system data needs to be recovered or not can be obtained, so that the system data can be flashed into the memory according to the data recovery requirement. When the system data is recovered, the system data in the independent disk can be formatted.
In an implementation manner, when recovering system data, the embodiment includes the following steps:
step S301, receiving the starting-up instruction and determining whether backup system data exists or not;
step S302, if backup system data exists, acquiring the data recovery requirement;
step S303, if the data recovery requirement is that recovery is needed, reading the system data in the independent disk, and flashing the system data into the memory;
and S304, formatting the system data in the independent disk, and supplying energy to a preset capacitor power supply.
In specific implementation, the terminal device of this embodiment receives the boot instruction and enters the boot program.
At this time, the terminal device determines whether there is backup system data, that is, determines whether to backup the system data when the terminal device was last powered off. If the backup data exists, it needs to be determined whether to restore the backup data, that is, whether to restore the system data backed up when the system is powered off last time is determined. If the backup data does not exist, the terminal equipment can be directly and normally started up at the moment when the last shutdown of the terminal equipment is described and the system data is backed up. If the backup data exists, the terminal equipment can output prompt information of data recovery requirements at the moment, and then whether the recovery needs to be continued is determined according to the prompt information. If the user selects that the system data needs to be recovered, namely the data recovery requirement is that the system data needs to be recovered, the terminal device reads the system data in the independent disk at the moment, and then the system data is flashed into the memory, so that the recovery of the system data is realized. And when the system data is recovered, the terminal equipment formats the system data in the independent disk in time to make room for the independent disk, so that the system data needing to be backed up can be stored conveniently when the system is shut down next time. After the terminal equipment is started, the terminal equipment supplies energy to the preset capacitor power supply, so that the energy stored by the capacitor power supply is convenient for completing data backup operation when the terminal equipment is shut down. In another implementation manner, if the data recovery requirement is that recovery is not required, the device is directly started and supplies energy to a preset capacitor power supply.
In summary, the present embodiment obtains current input data, and determines a shutdown state according to the current input data; according to the shutdown state, backing up system data to an independent disk; when a starting-up instruction is received, acquiring a data recovery requirement, flashing the system data into a memory according to the data recovery requirement, and formatting the independent disk. The invention can save the system data in time and independently save the system data in the independent disk, can effectively avoid the thorough data loss caused by system crash or equipment damage, effectively prevent sudden accidents, can effectively back up and restore the system data and has high reliability.
