이렇게 백업이 진행 된다.
옵션을 수정하지 않았다면 기본 백업 경로는
/var/opt/gitlab/backups/ 위치에 저장 되고
# ls
1701427000_2023_12_01_16.2.3_gitlab_backup.tar
tar 파일로 저장이 된다.
백업 경로는 수정하고 싶다면
# vi /etc/gitlab/gitlab.rb
위 파일을 수정하고 경로 수정 하면 된다.
gitlab.rb 파일을 수정하면 적용 시켜줘야 정상 작동이 된다.
적용 방법은
# gitlab-ctl reconfigure
# gitlab-ctl restart
이다.
복원은
# gitlab-backup restore 1701427000_2023_12_01_16.2.3_gitlab_backup.tar
백업된 파일을 /var/opt/gitlab/backups 로 복사 해주고 권한을 git:git 으로 변경해주자
# chown -r git:git /var/opt/gitlab/backups/*
이렇게 해주면 정상적으로 복원이 된다.
만약에 버전이 안맞는다면 위와 같이 버전이 안맞는다고 에러 뜬다 버전을 맞춰줘야 한다.
git 버전 확인 하는 방법은
# gitlab-rake gitlab:env:info
System information

이렇게 버전 확인이 가능하다.
특정 버전 설치는
yum install gitlab-ce-(원하는 버전)-ce.0.el6.x86_64 하면 된다.
yum install gitlab-ce-16.2.3-* 이렇게~
주기적인 백업을 하고 싶다면 crontab -e 를 이용해주면 된다.
# crontab -e
0 1 * * * /opt/gitlab/bin/gitlab-backup create CRON=1
하면 된다.
