摘　　要：石油行业地质资料数据具有数据量大、增长快和数据种类复杂等特点,如何备份这些海量的数据成了一大难题。以中国南海东部海域石油勘探数据为例,结合石油行业数据特点,设计了"两地三中心"的数据备份系统架构,建成了三级数据备份系统。该系统以NAS存储数据快照技术为基础,各级备份系统采用不同的备份策略,对应不同的风险级别,通过对各级备份数据进行恢复验证,各级备份数据都是完整有效的,取得了预期的效果,达到了系统建设的目的。The geological data of petroleum industry has the characteristics of large data volume,fast growth and complex data types.How to backup these huge data is a difficult problem.Taking the data of oil exploration in the eastern South China Sea as an example,combining with the characteristics of the oil industry data,the paper designs the Three Centers for Two Places data backup system architecture,and constructs the three-level backup system.The system is based on NAS storage data snapshot technology,and different backup strategies at all levels are adopted,corresponding to different levels of risk.Through the study of recovery verification,all levels of the backup data are complete and effective,and the expected results and the purpose of system construction are achieved.
