ephemeral data

基本解释

When you delete the virtual machine, the ephemeral storage is deleted and thus the data stored on that storage will be deleted.
当您删除虚拟机时，临时性存储会被删除，因此该存储中保存的数据也将随之被删除。

When you delete the instance, the instance is halted and the data in the ephemeral file system is deleted and is not recoverable, so you have to keep important data on other storage systems.
当删除实例时，实例将被停止，并且在临时文件系统中的数据也将被删除且不能恢复，因此，需要把重要的数据保存到其他的存储系统上。
