Referring to fig. 1, fig. 1 provides a network architecture of a data backup system according to an embodiment of the present invention, where the network architecture may include: the mobile terminal and the server can establish communication connection through a wireless fidelity network, a mobile communication network (such as 2G, 3G, 4G, 5G and the like) and a wired network. The system can be used for realizing the following process, the mobile terminal acquires a plurality of data types to be backed up, each data type to be backed up corresponds to one priority, each priority corresponds to one synchronization frequency, data corresponding to the plurality of data types to be backed up are monitored according to the synchronization frequency, when the situation that the data corresponding to the data type i have new data is monitored, the new data is backed up to the server, and the data type i is any one of the plurality of data types to be backed up.
Referring to fig. 2, a schematic flowchart of a first embodiment of a data backup method according to an embodiment of the present invention is shown based on the network architecture of the data backup system described in fig. 1. The data backup method described in this embodiment includes the following steps:
101. the method comprises the steps of obtaining a plurality of data types to be backed up, wherein each data type to be backed up corresponds to a priority, and each priority corresponds to a synchronous frequency.
The data types to be backed up can be set by a user, and the data types can be at least one of the following: photos, video files, address lists, short messages, audio files, word files, PDF files, application installation packages, application plug-ins and the like. For example, the plurality of data types to be backed up may be: photos and address books.
Alternatively, after the data types to be backed up are acquired, the priority of each data type to be backed up may be set by the user. For example, when the type of the data to be backed up is address book, video file, photo, and audio file, the corresponding priority may be address book, video file, photo, and audio file from high to low, and the synchronization frequency corresponding to each priority may be determined according to the corresponding relationship between the priority and the synchronization frequency. Of course, the correspondence between the priority and the synchronization frequency may be set before the embodiment of the present invention is performed.
Optionally, after determining the priority corresponding to each type of data to be backed up, the user may also set the synchronization frequency corresponding to each priority. For example, the types of data to be backed up are set as address book, file, photo and audio, the corresponding priorities are set as address book, video file, photo and audio file from high to low, the corresponding synchronization frequency with high priority is high, the corresponding synchronization frequency with low priority is low, the address book can be monitored once every 12 hours, the video file can be monitored once every 24 hours, the photo can be monitored once every 36 hours, and the audio file can be monitored once every 48 hours.
102. And monitoring the data corresponding to the types of the data to be backed up according to the synchronous frequency.
Each type of data to be backed up corresponds to a synchronization frequency, and the corresponding data is monitored according to the synchronization frequency. For example, the priority is sequentially from high to low for a communication list, a video file, a photo and an audio file, and the communication list is monitored once every 12 hours, the video file is monitored once every 24 hours, the photo is monitored once every 36 hours and the audio file is monitored once every 48 hours according to the set synchronous frequency. Different data types to be backed up are monitored through different synchronous frequencies, so that the backup frequency of each data type is different, all data types do not need to be monitored in real time, and changed data are reported to a server to implement data backup as soon as data corresponding to the data types change, so that the access times of the server are reduced, and the load of the server is lightened.
103. When it is monitored that new data occurs in data corresponding to a data type i, the new data is backed up to a server, and the data type i is any one of the multiple data types to be backed up.
The new data in the implementation of the present invention refers to data that has not appeared in the mobile terminal at the previous monitoring time, for example, a new photo taken at the previous monitoring time and the current monitoring time, for example, a newly downloaded movie taken at the previous monitoring time and the current monitoring time, or for example, a short message received at the previous monitoring time and the current monitoring time, currently, the mobile terminal may also perform a deletion operation on the data, but the deleted part is not new data. When it is monitored that new data occurs in data corresponding to any data type i, the new data can be backed up to a server, and the data type i is any one of a plurality of data types to be backed up.
Optionally, the backing up the new data to the server may include the following steps:
31) and judging whether the current access amount of the server exceeds a preset load threshold value.
32) And when the current access amount of the server exceeds the load threshold value, executing the backup of the new data to the server within a preset time period.
The load value of the server may be represented by a load pressure borne by a processor used for representing the mobile terminal, and in general, the load value of the server may be represented by a percentile system, of course, the more programs the server runs, the greater the corresponding load pressure, or the greater the access amount of the server, the greater the corresponding load pressure.
The preset load threshold value can be set by a user or defaulted by a system. The preset time period can be set by the user, or the mobile terminal acquires the preset time period from the server. The preset time period may be: 13:00-18:00, or the preset time period may be acquired in the following manner: the server counts the user access amount in a period of time, and marks the time period in which the user access amount is less than a certain threshold value, so that the server is relatively idle when the access amount of the server is less in each day, and the time period in which the access amount of the server is less can be used as a preset time period. Before the new data is backed up to the server, whether the current access amount of the server exceeds a preset load threshold value or not can be judged, and when the current access amount of the server exceeds the preset load threshold value, the new data can be backed up to the server within a preset time period so as to avoid that the access pressure of the server is too high and exceeds the preset load threshold value. For example, the preset time period may be: two points in the morning to seven points in the morning, the access amount of the server in the time period is small, and the backup can be automatically delayed to be executed in the preset time period by setting the mobile terminal.
Optionally, the backing up the new data to the server may include the following steps:
33) judging whether the size of the memory occupied by the new data exceeds a first preset threshold value or not;
34) when the size of the memory occupied by the new data exceeds the first preset threshold value, splitting the new data into a plurality of data packets, and backing up the data packets to the server by adopting multiple threads or multiple processes;
35) and when the size of the memory occupied by the new data is smaller than or equal to the first preset threshold value, backing up the new data to the server.
The first preset threshold value can be set by the user or the system defaults. When the size of the memory where the new data is located exceeds a first preset threshold, the new data can be split into a plurality of data packets, and the data packets are backed up to the server by adopting multiple threads or multiple processes, so that the backup efficiency can be improved. When the size of the memory occupied by the new data is smaller than or equal to the first preset threshold value, the new data can be backed up to the server, so that when the memory occupied by the new data is smaller, the new data is directly backed up to the server without being split into a plurality of data packets. Therefore, whether the multi-process or the multi-thread is adopted can be determined according to the memory size of the new data, so that the power consumption of the mobile terminal can be reasonably reduced, and the new data can be quickly backed up.
Furthermore, the mobile terminal may implement data backup on the new data by using a multithread or multiprocess mechanism, after the new data is split into a plurality of data packets, each data packet may correspond to one thread or one process, taking the data type as a photo as an example, the plurality of photos are split into a plurality of data packets, and the plurality of data packets are backed up to the server, so as to improve the backup efficiency.
It can be seen that, according to the embodiment of the present invention, a plurality of data types to be backed up are obtained, each data type to be backed up corresponds to one priority, each priority corresponds to one synchronization frequency, data corresponding to the plurality of data types to be backed up is monitored according to the synchronization frequency, when it is monitored that new data occurs in the data corresponding to the data type i, the new data is backed up to the server, and the data type i is any one of the plurality of data types to be backed up. Thus, it is possible to reduce the access frequency to the server, i.e., reduce the amount of access to the server, by adjusting the synchronization frequency.
In accordance with the above, please refer to fig. 3, which is a flowchart illustrating a data backup method according to a second embodiment of the present invention. The data backup method described in this embodiment includes the following steps:
301. the method comprises the steps of obtaining a plurality of data types to be backed up, wherein each data type to be backed up corresponds to a priority, and each priority corresponds to a synchronous frequency.
302. And monitoring the data corresponding to the types of the data to be backed up according to the synchronous frequency.
303. And when it is monitored that the data corresponding to the data type i has new data, judging whether the memory size of the new data is larger than a second preset threshold value.
Wherein, the second preset threshold value can be set by the user or the system defaults. Firstly, the memory size of the new data corresponding to the data type i can be determined, and then whether the memory size is larger than a second preset threshold value is judged.
Specifically, the second preset threshold determines whether to back up new data to the server when it is monitored that new data exists in the data type i. For example, the data type is used as a photo for explanation, the second preset threshold is 100 million, the photo is monitored once every 36 hours through the set synchronization frequency, when new data (multiple photos) is monitored and the memory occupied by the new data is greater than 100 million, the 100 million new data is backed up, namely the data is backed up to the server, and when the memory occupied by the new data is less than 100 million, the data backup is not performed, and the photo is continuously monitored according to the synchronization frequency. Therefore, when the number of new data is small, the server is not accessed, and therefore, the access amount of the server can be reduced. When a user does not frequently use a camera to take pictures or the mobile terminal only adds a few photos, the size of the newly added photo data may not exceed 100 megabytes, and the backup of the photo data is not needed, so that the access pressure on the server is reduced while the use of the user is not influenced.
304. And when the memory size of the new data is larger than the second preset threshold value, backing up the new data to a server, wherein the data type i is any one of the multiple data types to be backed up.
It can be seen that, according to the embodiment of the present invention, a plurality of data types to be backed up are obtained, each data type to be backed up corresponds to one priority, each priority corresponds to one synchronization frequency, data corresponding to the plurality of data types to be backed up is monitored according to the synchronization frequency, when it is monitored that new data occurs in the data corresponding to the data type i, and when the memory size of the new data is greater than a second factor threshold value, the new data is backed up to the server, and the data type i is any one of the plurality of data types to be backed up. Therefore, the method can be used for reducing the access frequency to the server by adjusting the synchronization frequency, and by setting the second preset threshold, the server is accessed only when the memory size of the new data is larger than the second preset threshold, so that the access amount of the server can be reduced.
In accordance with the above, please refer to fig. 4, which is a flowchart illustrating a data backup method according to a third embodiment of the present invention. The data backup method described in this embodiment includes the following steps:
401. the method comprises the steps of obtaining a plurality of data types to be backed up, wherein each data type to be backed up corresponds to a priority, and each priority corresponds to a synchronous frequency.
402. And monitoring the data corresponding to the types of the data to be backed up according to the synchronous frequency.
403. And when the situation that the data corresponding to the data type i has new data is monitored, determining the current electric quantity of the mobile terminal.
The mobile terminal can detect the running state of the battery, and therefore current electric quantity is obtained.
404. And judging whether the current electric quantity can finish the backup of the new data to the server or not.
Optionally, the mobile terminal may determine an expected backup electric quantity according to the size of the memory of the new data, and if the current electric quantity is greater than the expected backup electric quantity, it indicates that the current electric quantity can complete the backup of the new data to the server. And if the current electric quantity is less than or equal to the expected backup electric quantity, the current electric quantity is proved to be incapable of completing the backup of the new data to the server. The mobile terminal may determine the expected backup power according to the size of the memory of the new data, and the specific implementation manner may be as follows: the mobile terminal can obtain its backup record and further determine how much data can be transmitted when consuming 1% of the power. Thus, the memory size of the new data may be determined to result in the expected amount of backup power.
405. And when the current electric quantity can finish the backup of the new data to the server, the new data is backed up to the server, and the data type i is any one of the multiple data types to be backed up.
Optionally, when the current electric quantity cannot finish the backup of the new data to the server, the user is prompted to charge, if the mobile terminal is in a charging state, the new data is backed up to the server, and the data type i is any one of a plurality of data types to be backed up.
It can be seen that, according to the embodiment of the present invention, a plurality of data types to be backed up are obtained, each data type to be backed up corresponds to one priority, each priority corresponds to one synchronization frequency, data corresponding to the plurality of data types to be backed up is monitored according to the synchronization frequency, when it is monitored that new data occurs in the data corresponding to the data type i, and when the memory size of the new data is greater than a second factor threshold value, the new data is backed up to the server, and the data type i is any one of the plurality of data types to be backed up. Therefore, the method can be used for reducing the access frequency to the server by adjusting the synchronous frequency, and data backup can be performed only when the current electric quantity can complete data backup of new data, so that the access quantity of the server can be reduced, and the success rate of the data backup can be ensured.
