이중성: 백업이 다시 시작되지만 현재 암호화 설정이 원래 설정과 일치하지 않습니다.

저는 이중성을 사용하여 파일을 Backblaze B2에 백업했습니다. 며칠 전까지만 해도 이 방법은 매우 효과적이었습니다. 로컬 Python 라이브러리를 제거했다가 다시 설치했습니다. 또한 source현재 포함된 두 번째 스크립트로 비밀번호를 추출했습니다 . 업로드가 실패하고 다음 메시지가 계속해서 나타납니다.

Backblaze B2에 온라인으로 접속하여 간단히 복구되기를 바라면서 마지막 아카이브와 서명 파일을 삭제했지만 복구되지 않았습니다. 이제 Duplicity의 출력은 다음과 같습니다.

호출은 다음과 같습니다.

set -u모든 변수가 설정되었습니다. 정의되지 않은 변수로 종료를 활성화하고 set -x명령이 예상한 대로 작동하는지 확인했습니다.

온라인에서 모든 파일을 삭제하고 새로운 전체 백업으로 다시 시작할 수도 있지만 문제가 다시 발생하면 해결할 수 있도록 문제를 이해하고 싶습니다.
