Problems solved by technology

[0003] At present, similar technologies are implemented in Linux systems and other fields based on databases and processes for data backup and restoration. However, this type of technology requires backup and restoration managers to be deeply involved in the backup content and purpose of the backed up data, and needs to be customized for different backup targets. Strong coupling, heavy workload, strong customization
Not suitable for the extensiveness and consistency of task backup and restore at the operating system level

[0099] Figure 2A Shown is a first embodiment of a method for computer system data backup and a corresponding general flow of a first embodiment of a method for computer system data restoration, both of which are used in conjunction. Wherein, above the dotted line is the step of the first embodiment of the method for computer system data backup, which includes:

[0100] Step 110, determine the current checkpoint interval of the user partition.

[0101] Among them, this step sets the current checkpoint interval based on the time of user partition failure and the frequency of user partition failure. For a detailed description, please refer to [Checkpoint interval setting method] described later.

[0102] From the above, from the effect of recovering data, the smaller the checkpoint interval, the better. In this way, when the user partition fails, the restored data will be closer to the failure point, but too small checkpoint interval will affect the efficiency of the user parti...

[0274] The second embodiment of an apparatus for restoring computer system data is used in conjunction with the second embodiment of an apparatus for backing up computer system data. The following is also based on Figure 5C A second embodiment of the device for restoring data in a computer system is introduced, which includes the following modules:

[0275] The status monitoring module 540 is used for the computer system to detect the operating status of each user partition, detect whether there is a fault in each user partition, and determine the acquisition node of the backup data and the selected recovery checkpoint when a fault occurs. The working principle and advantages of this module are the same Step 240 of the second embodiment of the method for computer system data restoration will not be described in detail here.

[0276] The restoration node selection module 550 is used for the computer system to select a restoration node for restoring the user partition based on ...

Abstract

The invention provides a method for backing up computer system data, which comprises the following steps of: generating a partition snapshot at each check point of a user partition on the basis of data of a related operating system of the user partition in a memory of a running node, wherein each time window indicates the corresponding check point; and backing up the partition snapshots generatedby the check points. The invention further provides a method for recovering computer system data. Based on the backed-up partition snapshots, the data of the related operating systems of the user partitions are recovered in the memory of the recovery node. The invention also correspondingly provides a device corresponding to each method. The method and the device do not depend on user partition tasks, are suitable for various user partition tasks, and guarantee real-time and high-reliability operation of a computer system.

Description

technical field [0001] This application relates to the field of computer operating systems, in particular to the field of computer system data backup and restoration. Background technique [0002] Computer system fault-tolerant recovery technology is the basis to ensure the efficient, safe, reliable and real-time operation of various tasks. [0003] At present, similar technologies are implemented in the Linux system and other fields based on databases and processes for data backup and restoration. However, this type of technology requires the backup and restoration manager to be deeply involved in the backup content and purpose of the backed up data, and needs to be customized for different backup targets. High coupling, heavy workload, and strong customization. It is not suitable for the extensiveness and consistency of task backup and restoration at the operating system level. Contents of the invention [0004] In view of this, the present invention provides a method ...
