-C 전송시 파일을 압축해서 전송한다.

-l 전송속도 옵션이다. 단위는 Kbit/s

-P 포트지정 옵션이다. 22번 포트는 생략하여도 된다.

-p 원본 파일과 시간을 동일하게 복사한다.

-q 전송진행 상태를 안보여준다.

-r 하위 디렉토리까지 같이 복사하다.

-v 디버깅메시지를 보여준다. 그러나 너무 분잡하다.

테스트용 디렉토리와 100MByte 파일 생성

[root@conoha ~]# dd if=/dev/zero of=./testdir/subdir/100M.bin bs=100M count=1

1+0 records in

1+0 records out

104857600 bytes (105 MB) copied, 0.227941 s, 460 MB/s

30Mbps 속도로 원격지 서버에 testdir 디렉토리를 전송 (속도가 제어되어서 전송되었다.)

[root@conoha ~]# scp -P10022 -l30000 -pr ./testdir/ root@vultr.ivps.kr:~/testdir/

100M.bin                                      100%  100MB   3.7MB/s   00:27

속도제한 없이 원격지 서버에 전송 (160Mbps 속도가 나온다.)

[root@conoha ~]# scp -P10022 -pr ./testdir/ root@vultr.ivps.kr:~/testdir/

100M.bin                                      100%  100MB  20.0MB/s   00:05

압축해서 원격지 서버에 전송 (800Mbps 속도가 나왔다. 더미파일이라서 압축효과가 있다.)

[root@conoha ~]# scp -P10022 -Cpr ./testdir root@vultr.ivps.kr:~/

100M.bin                                      100%  100MB 100.0MB/s   00:01

이번엔 원서버에 원본 디렉토리를 지우고

[root@conoha ~]# rm -rf testdir

원격지 서버의 testdir 디렉토리를 다운로드

[root@conoha ~]# scp -P10022 -Cpr root@vultr.ivps.kr:~/testdir ~/

100M.bin                                      100%  100MB  50.0MB/s   00:02

[root@conoha ~]# scp -P10022 -pr root@vultr.ivps.kr:~/testdir ~/

100M.bin                                      100%  100MB  20.0MB/s   00:05

[root@conoha ~]# ls -l ~/testdir/subdir/
