导读 gitlab的默认备份路径是/var/opt/gitlab/backups/，可以通过gitlab.rb来修改这个配置路径，gitlab_rails['backup_path'] = "/data/pgsql_bak"
1，全备份
集成包安装：
# gitlab-rake gitlab:backup:create

源码安装
# git -H bundle exec rake gitlab:backup:create RAILS_ENV=production

docker安装
# docker exec -t <容器名> gitlab-rake gitlab:backup:create
2，部分备份

db (数据库)
uploads (附件)
repositories (代码库)
builds (CI作业输出日志)
artifacts (CI工件)

集成包安装：
# gitlab-rake gitlab:backup:create SKIP=uploads,repositories,builds,artifacts,lfs,registry,pages

源码安装
# git -H bundle exec rake gitlab:backup:create SKIP=uploads,repositories RAILS_ENV=production

docker安装
# docker exec -t <容器名> gitlab-rake gitlab:backup:create SKIP=uploads,registry,pages
3，crontab
集成包安装：
0 7 * * * /opt/gitlab/bin/gitlab-rake gitlab:backup:create CRON=1

源码安装
