求助!为 docker 里的 gitlab 做远程备份一直不成功

服务器是 windows server 2012 r2,gitlab 跑在虚拟机里的 centOS7 的 docker 里,想要把 gitlab 备份到 window 的文件夹内,尝试了若干办法均不成功,目前的现象是执行备份不报错,但是只有容器内 /var/opt/gitlab/backups 文件夹内有备份文件,共享文件夹没有,还是 v 站请教下各位大佬帮忙指点下

docker 的运行配置

docker run \ -itd \ -p 80:80 \ -p 443:443 \ -p 22:22 \ -v /usr/local/gitlab/etc:/etc/gitlab \ -v /usr/local/gitlab/log:/var/log/gitlab \ -v /usr/local/gitlab/opt:/var/opt/gitlab \ -v /mnt/gitlab-backups:/mnt/host/gitlab-backup\ --restart always \ --privileged=true \ --name gitlab \ gitlab-test 

//linux 下挂载目录的命令(尝试过 hgfs 跟 cifs,现在用的是 cifs)

//192.168.1.220/gitlab-backup-share /mnt/gitlab-backups cifs auto,username=Administrator,passwd=admin@123,file_mode=0777,dir_mode=0700,uid=998,gid=998,iocharset=utf8 0 0 

//这个 uid 跟 gid 是因为容器内 git 账户 uid 是 998,中间开启 manage_backup_path 选项的时候报错想到的歪主意

gitlab 的配置(省略了无关项)

#gitlab_rails['backup_path'] = "/mnt/host/gitlab-backup" #直接把备份路径指向挂载的文件夹,备份最后的时候会报 file changed as we read it 错误 gitlab_rails['manage_backup_path'] = true gitlab_rails['backup_upload_connection'] = { :provider => 'Local', :local_root => '/mnt/gitlab-backups' } gitlab_rails['backup_upload_remote_directory'] = 'gitlab_backups' gitlab_rails['backup_archive_permissions'] = 0644 gitlab_rails['backup_keep_time'] = 604800 user['username'] = "root" user['group'] = "root"
