Abstract

The invention provides an information system disaster recovery time objective calculation method. The key of the method is that k services (K1, K2...Kk) altogether operate on an information system comprising m production systems and that each service only can operate on one production system. By analyzing the importance of each production system in the information system, the importance of each service, the profit produced per second by each department and post-disaster tolerable loss, and on the basis of the post-disaster tolerable loss related to a service, the profit newly produced per second by each service, the profit newly produced per second by the production system related to the service and post-disaster tolerable loss are estimated according to the percentage of the post-disaster tolerable loss of the service used by a department accounting for the total post-disaster tolerable loss of the department, and according to the importance of each production system in the information system and the CPU (Central Processing Unit) load condition, the ratios of the tolerable losses to the produced profits of the production systems are weighted and averaged in order to work out the RTO (recovery time objective) value of the disaster recovery point objective of the whole information system.

Description

Technical field

[0001] The invention relates to a method for calculating the disaster recovery time target of an information system, which can scientifically calculate the disaster recovery points needed in the disaster recovery construction of the information system by analyzing the CPU load, business volume and related data of the existing business system Target (RTO: RecoveryTime Object) indicator. Background technique

[0002] According to the definition in the national standard "Information System Disaster Recovery Specification" (GB / T20988-2007): a disaster refers to a serious failure or paralysis of an information system due to man-made or natural reasons, which makes the business function or service level supported by the information system stop Unacceptable, unexpected events that reach a specific time. Typical disaster events include natural disasters (such as fire, flood, earthquake, wind disaster, etc.), equipment disasters (such as equipment failure, software error,...
