This paper presents the process for research and implementation a database proxy module in Oracle of the database backup software H-info Backup. This software used the modular design,and has 5 major modules:Director(As the Server of other backup software),File Daemon(as the client of other backup software),Storage Daemon(Storage Server),Console(Control backup and recovery),Catalog DataBase(Background database for record the Job information of backup and recovery).While the software running,the database proxy module transfer a dynamic link library(DLL) to the File Daemon.This DLL includes functions of backup and recovery for database.File Daemon dynamically loaded DLL to call these fuctions,then backup and recovery a concrete database.The H-info Backup also provided the logical backup.The test environment is OS:windows2000,CPU:Celeron 2.4 GB,Memory:768 MB.Under such a test environment,this software worked well in logical backup.And the speed of physical backup almost equals to that of other backup software.
