BackupPc不备份挂载的LVM快照吗？

Question

我重新设置了我的BackupPc并遇到了一个问题：

我想备份所有主机上的"/backup“。为了测试目的，我从一个主机开始。

进程：

1. BackupPC在客户端上调用Shell脚本。
2. 该脚本生成一些快照并将其挂载到/backup/.
3. 现在BackupPC应该备份
4. 至少BackupPC调用另一个Shell-Script，它卸载并删除快照。

/backup得到“备份”，但只得到文件夹，而不是它们的内容。

我增强了第一个shell脚本，以确保文件夹有内容，在这里输出如下：

您可以看到列出了“docker-come.yml”的文件，但是备份是空的。

这里有什么问题吗？

Answer 1

通过将RsyncArgs从默认更改为BackupPC 3中的Args (默认情况下)，它起了作用：
