일자별로 자동으로 begin backup을 수행하는 백업 스크립트(backup script)

 

-- 실전 오라클 백업과 복구(생능출판사, 서진수 지음), p.224~p.229
-- 일자별로 자동으로 begin backup을 수행하는 백업 스크립트
-- 로그 확인: /u01/app/oracle/total.log
-- 실행: sh main_backup.sh
-- main_backup.sh를 crontab에 등록해 두면 아주 쉽게 주기적으로 백업을 수행 할 수 있습니다.

-- 1. main_backup.sh

-- 2. begin_backup.sh

-- 3. copy_backup.sh
