Embodiment 1
[0032] This embodiment provides a data protection method for ensuring application consistency. By analyzing the relationship between various data components of the application system, the sequential dependency relationship between each data component is found, and data backup at different times is implemented based on the dependency relationship. Such as figure 2 As shown, the method includes the following steps:
[0033] Obtain application configuration information, the configuration information includes data components and dependencies between data components, such as figure 1 shown;
[0034] When performing data backup, create an application-level backup task, and record the backup time point as a data recovery instruction at the same time, create backup subtasks for each data component based on the dependencies, and determine the scheduling sequence of each backup subtask, based on the The scheduling completes each of the backup subtasks sequentially, and then completes...
Embodiment 2
[0040] refer to figure 2 As shown, this embodiment provides a data protection device that ensures application consistency, including an instruction receiving module and an orchestration and scheduling module, wherein the instruction receiving module is used to obtain application configuration information and data recovery instructions, and the configuration information includes data Dependencies between components and various data components; the orchestration and scheduling module is used to perform data backup and data recovery operations, specifically,
[0041] In response to the set data backup command, create an application-level backup task, and record the backup time point as the data recovery command, create backup subtasks for each data component based on the dependency relationship, and determine the scheduling sequence of each backup subtask , completing each of the backup subtasks in sequence based on the scheduling, and then completing the application-level backu...
Embodiment 3
[0047] This embodiment provides a data protection system for ensuring application consistency, including one or more processors, memory, and one or more programs stored in the memory, the one or more programs include a system for executing such as Instructions of the data protection method for ensuring application consistency described in Embodiment 1.
