服务器即将到期，准备把数据进行快照，分别选择七牛云和阿里oss 测试，最终快照结果都是
socket ignored tar错误，一开始以为是服务运行中导致，我把所有docker停止继续备份仍然抱错，麻烦官方帮忙确认下具体原因，下面是具体错误信息

1、将 docker.service 和 docker.socket 都手动停止后试一下，具体命令如下：
systemctl stop docker.service
systemctl stop docker.socket
2、还可以在创建快照前，可以手动清理一下无用的镜像、容器，具体命令如下：
docker system prune -a --volumes -f
快照功能还在测试中，命令1 手动停止docker后，进行快照提示无法链接docker，所以必须要打开才行。
问题2： 快照业务除了docker本身，是否包含我们额外在宿主机安装的程序和进程服务
碰到的问题，停止服务后，任务状态未变更，清理无用镜像后，提示database is lock

我刚刚把code-server删了就只剩下mongodb的错误，现在把mongodb删除在试试。不行就重启看。
在进行网站单独备份时， 网站备份周期太长，而且不成功
删除2个服务后，没出现新的错误，但是也没有成功,无错误原因，继续测试1pctl restart，重启后的失败信息与前一次相同。
