protection和restoration的区别:
The term protection is used to denote the paradigm whereby a dedicated backup resource is deployed to recover the services provided by a failed resource. In contrast, the term restoration is used to denote the paradigm whereby backup resources are not dedicated to specific primary resources, but a pool of resources is kept available for overall recovery purposes.

跳舞,像没有人注视一样
唱歌,像无人聆听一样
热恋,像从未受过伤
活着,即把人间当做天堂
