OS환경 : Oracle Linux 7.4 (64bit)
DB 환경 : Oracle Database 19.3.0.0
방법 : 오라클 19c rman backup set 방식과 image copy 방식 백업 크기 비교
오라클 19c에서 rman으로 백업할때는 2가지 방식을 사용해서 백업할 수 있음
하나는 backup set 방식이고 하나는 image copy 방식임
이 두 백업방식을 각각 진행하면서 백업 크기를 비교해봄

데이터파일 갯수만큼 백업파일이 만들어짐
이중 ORACLE19_data_D-ORACLE19_I-3209222764_TS-RMANTS_FNO-5_072ejhq9_20231221_imgcopy.bk가 11gb임
총 13gb가 백업됨
백업된 전체용량을 보면 datafile 할당 기준으로 용량을 확인했을때와 비슷함
결론 : rman 백업방식에서 backup set 방식으로 백업할때는 사용하는 segment 만큼만 백업을 받고(2.4gb)
image copy 방식으로 백업할때는 os에서 파일을 복사할때 사용하는 cp명령어가 수행되는것처럼 용량이 거의 그대로 복사가됨(13gb)
참고로 19c docs에 보면 이렇게 작성되어 있음
Note:Data file backup sets are typically smaller than data file image copies and take less time to write.
메모:데이터 파일 백업 세트는 일반적으로 데이터 파일 이미지 복사본보다 작으며 쓰는 데 시간이 덜 걸립니다.
