BackupPc 不备份挂载的 LVM 快照？

Question

我重新设置了我的 BackupPc 并且运行遇到了一个问题：

我想在所有主机上备份“/backup”。为了测试目的，我从一台主机开始。

进程：

BackupPC 在客户端调用 Shell-Script
该脚本生成一些快照并将它们装载到 /backup/...
现在 BackupPC 应该备份
至少 BackupPC 调用另一个 Shell-脚本，卸载并删除快照

/backup 得到 "backed up" 但只是文件夹，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，这里是输出：

您可以看到列出了一个文件 "docker-compose.yml"，但备份是空的

这可能是什么问题？

Answer 1

通过将 RsyncArgs 从默认更改为我在 BackupPC 3 中（默认情况下）使用的 Args，它起作用了：
