高性能数据拯救系统DataSafe的设计

Design of High Performance Data Rescue System DataSafe

研发的DataSafe是一款高性能数据拯救系统,它采用备份服务器端自动合并技术,支持各种基于块变更跟踪的数据备份技术,实现了只需要在初始化阶段做一次全量备份,此后只需要做增量备份即可,并且可快速恢复,数据库恢复的时间与数据库规模无关。文中介绍了DataSafe系统的总体功能架构和系统创新特点。

The developed DataSafe is a high performance data rescue system,which uses the backup server-side automatic merging technology to support various data backup technologies based on block change tracking.It only needs to do a full backup in the initialization stage,and only needs to do an incremental backup after that,and it can recover quickly.The database recovery time has nothing to do with the database size.This paper introduced the overall function architecture and system innovation features of DataSafe system.
