Embodiment Construction

[0027] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the present invention.

[0028] In this embodiment, a DAG-based complex disaster recovery switching process rollback method is provided, including the following steps,

[0029] S1. According to the component switching sequence inside the information system, generate a switching DAG inside the information system, that is, a component-level DAG; see the attached figure 1 (When each component is more complicated, it can also generate its own DAG, that is, the sub-component level DAG).

[0030] S2. According to the switching dependency sequence between information systems, generate a switching DAG between information systems...

Abstract

The invention discloses a DAG-based complex disaster recovery switching process rollback method, which includes the following steps: S1. According to the component switching sequence inside the information system, generate a switching DAG inside the information system, that is, the component level DAG; S2. According to the information The switching between systems depends on the sequence, and the switching DAG between information systems is generated, that is, the information system level DAG; S3. According to different fallback scenarios, the corresponding fallback process is performed in combination with the component level DAG and the information system level DAG. The advantage is that the process of disaster recovery switching is planned based on DAG, and the corresponding DAG is formed. The user performs the complex disaster recovery switching process rollback according to the rollback path.

Description

technical field [0001] The invention relates to the technical field of IT operation and maintenance, in particular to a DAG-based method for rolling back complex disaster recovery switching processes. Background technique [0002] Since the emergence of information technology, various disaster problems faced by information systems have been repeated many times. After a disaster occurs, the process of restoring an information system from a disaster or paralyzed state to a normal operating state is called disaster recovery. In the process of disaster recovery or switching drill, each information system needs to strictly control the execution sequence of each step according to its inherent interdependence to complete the switching target or system recovery. When there are many associated information systems, the entire disaster recovery switching process will become more complicated. Under the conditions of complex disaster recovery switchover process, various abnormal or une...
