-depth여기서 문제는 find. 이는 find디렉터리 자체보다 먼저 디렉터리 내용을 처리하도록 지시합니다.

출력에서 볼 수 있듯이 find . -depth -print | cpio -ov > backup.cpio:

  • ./eBooks/logstash_atlantis/03_output.conf디렉토리 이전 처리./eBooks/logstash_atlantis
  • ./eBooks/Container-Networking-Docker-Kubernetes.pdf이전에 처리되었습니다 ./eBooks.
  • ...

아카이브를 추출하려고 하면 디렉터리가 아직 존재하지 않기 때문에 하위 디렉터리의 모든 파일이 실패합니다("열 수 없음: 해당 파일 또는 디렉터리가 없습니다").

또한 ./backup.cpio디렉터리에 이미 존재하기 때문에 실패합니다.

해결책:에는 -depth옵션을 사용 하지 마십시오 .findcpio
