Data Backup And Disaster Recovery Technology Application In Telecom Billing System

Data lost will interrupt normal business, resulting in the huge economy expense. For telecommunication industry, the safety of data is vary important, its data not only is the resources of enterprise development, but also is the key basis which provide service to the customer. Most business of telecommunication has to depend on data processing. If there is no data, the telecommunication business will all be placed in to paralyze appearance. If the computer system of telecommunication break down, in addition to result in huge loss of economy, more importantly, will lose the market and trust of customer probably. For the billing system, customer service system business support system and etc. , must build up an effectively perfect system of backup and disaster recovery.Along with the technical development and the market competition, the scale of the system of IT is more and more big, data quantity increase very faster, the data of T class already very familiar, the data of billing system get to several ten Ts even ascend 100 Ts, data scale more and more big but the backup window is more and more small, have to adopt the suitable method to solves data backup and disaster recovery.This article introduces the definition of data backup, disaster recovery and pigeonhole, and analyzes the differences of disaster recovery and data backup, the differences of data backup and pigeonhole. We should use different methods of backup according to data size and speed of backup and speed of recovery.According to this conclusion, for Shandong CNC billing system, design a new scheme of data storage backup and disaster recovery. We realize local data backup through technology of BCV, copy data to remote side through SRDF, backup database logically through Oracle's RMAN, backup each table with Oracle's exp. This scheme exert ability of hard ware, resolve the bottle-neck of data backup and disaster recovery. Now it runs well.
