The invention discloses a
backup disaster recovery optimization method, and relates to the technical field of IT operation and maintenance and
disaster recovery, and the method comprises the steps: analyzing a statistical dependency relationship between basic performance indexes through employing a causal discovery
algorithm based on a standardized
monitoring data flow, and constructing a directed weighted graph; when a basic
performance index in the directed weighted graph deviates from a normal performance baseline, triggering a reverse
traceability positioning
root cause component, identifying a service influence path through forward path analysis, and generating a
backup enhancement instruction; in a digital twin environment, according to historical
drill records and a strategy
library, multiple potential
disaster recovery switching schemes are generated, parallel deduction is carried out, the performance influence of each potential disaster
recovery switching scheme on a virtual service link is quantitatively evaluated in the deduction process, and the optimal disaster
recovery switching scheme is selected by comparing evaluation results. According to the invention, the prospective optimization of the disaster
recovery decision and the minimization of the business influence are realized, and the
automation, intelligence and business
adaptation capabilities of the
backup disaster recovery
system are enhanced.
