Problems solved by technology

[0003] However, the backup time interval of the current scheduled backup is fixed. For example, if the user sets the backup time interval through the menu page, such as 10 minutes, the application will automatically perform a backup every 10 minutes
However, the data in the time period between the two automatic backups still cannot be backed up in time. If the user has made a relatively large data modification without backing up during this time period, a large loss will occur
If the user sets the time interval of the scheduled backup to be shorter, the risk of data loss is relatively small, but the backup during editing will cause a strong sense of interruption, which will lead to a decline in user experience

Embodiment 1

[0028] see figure 1 , which is a flow chart of the data backup method of the present invention. This data backup method comprises the steps:

[0029] Step S11: Open or create a new file.

[0030] Step S12: call the backup parameter of the previous backup, and obtain the time interval value of the next backup according to the backup parameter.

[0031] In this embodiment, the time interval value of the next backup is obtained by means of a lookup table, and the time interval value lookup table is as follows:

[0032] The backup time of the previous backup Interval value for next backup

0 30s

≤500ms 30s

≤1s 60s

≤10s 200s

≤20s 300s

＞20s Backup according to the "time interval" value set by the user

[0033] Specifically, for a new file, the time-consuming value of its previous backup is set to 0 by default. It can be seen from the above table that the shorter the backup time of the current bac...

Embodiment 2

[0057] The data backup method of this embodiment 2 is roughly the same as the data backup method of embodiment 1, the only difference being that: the step S12 is replaced by: call the backup parameter at the current running time, and obtain the time interval of the next backup according to the backup parameter value.

[0058] Wherein, the backup parameters at the current running time are the file size x value and the current memory size a value. The time interval value y of the next backup is calculated through a convergence function y=f(a,x). Specifically, the function is:

[0059] y = f ( a , x ) = 20 × ( 1 + 200 x ) x 100 × 1 ...

Abstract

The invention relates to a data backup method. The data backup method comprises the following steps: D1. obtaining a backup parameter and obtaining a time interval value of next backup according to the backup parameter; D2. recording the backup time interval value obtained by a backup time interval calculation module, and timing; D3. when execution time is up, backuping a file; and D4. recording the backup parameter of current backup. Relative to the prior art, the data backup method and the data backup device can automatically and dynamically adjust a file backup time interval according to a file data modification situation so as to perform an automatic backup operation.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a data backup method and device. Background technique [0002] In the field of computer applications, data backup refers to the process of copying all or part of the data collection in the computer to other storage locations. The computer's file system is the core module of application program (such as office software) file management, and manages the local persistence of data of the application program. In the process of using the software, users often encounter the situation that the program exits abnormally, and the previous work results are lost instantly because they are not saved. In order to avoid the occurrence of the above situation, the application software generally provides the function of scheduled backup. The so-called scheduled backup means that the application program checks whether the currently running document is saved every once in a while, and...
