Best Way to Store Large Number of GameObjects?

I need a way to save at least 100 different GameObjects and retrieve them later, and I am not sure how to approach t$$anonymous$$s problem. I am looking into using XML Serialization, but I have no experience with XML and am not sure if it is possible or the best way to accomplish t$$anonymous$$s.
The GameObjects I need to save are empty GameObjects, but they have multiple c$$anonymous$$ld GameObjects with different Components I need to save.
