서버 간의 대용량 파일 이동이나 복제가 잦아지면서 원격 저장소가 필요해짐

구글 드라이브 저장용량을 구매해서 사용하고 있고, 다른 프로그램과 연동이 가능한 점에서 구글 드라이브를 선택함

흔히 사용되는 wget을 활용하는 방법을 알아보다가 용량이나 권한의 한계로 gdown을 사용함

wget 보안 문제 해결 방법

wget 옵션에 쿠키를 설정해서 다운로드 할 수 있는 방법

1. Git LFS

git은 100MB 이상의 파일 업로드에 제한이 있으며, 대안으로 Git Large File Storage(LFS)가 있음

Git LFS 사용하기

다만 lfs 용량 제한이 있는데, Github와 Bitbucket은 1GB, GitLab은 10GB의 용량을 제공하고, 용량 추가시 돈을 지불해야한다.
