나중에 테스트해볼것으로 ㅎ 와드입니당 

Docker 볼륨을 로컬로 백업하거나 S3, WebDAV, Azure Blob Storage, Dropbox 또는 SSH 호환 스토리지에 백업하세요.

offen /docker-volume-backup Docker 이미지는 기존 Docker 설정에 대한 경량(15MB 미만) 동반 컨테이너로 사용할 수 있습니다. Docker 볼륨을 로컬 디렉터리 , S3 , WebDAV, Azure Blob Storage, Dropbox 또는 SSH 호환 스토리지(또는 이들의 조합)에 대한 반복 또는 일회성 백업을 처리 하고 구성된 경우 오래된 백업을 순환시킵니다. 또한 GPG를 사용하여 백업을 암호화 하고 (실패한) 백업 실행에 대한 알림을 보내는 기능 도 지원합니다 .
