java - JPA: Embedding an entity for one case, but linking it in another

Question

I have several @Entity classes that are used throughout the code.

@Entity
@Table(name = "foo")
public class Foo {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long foo_id;

    @Column(name="my_name")
    private String name;

... (10+ fileds that will likely be changed throughout the development)

}

I need to create a system that will archive this Entity and similar ones (each one in its own table) adding a snapshot time, so the resulting archive table looks somewhat like:

Archive rec id	Snapshot time	foo_id	name	...
1	12.01.2021 10:00	1	foo1	...
2	12.01.2021 11:00	1	foo1	...
3	12.01.2021 11:00	2	foo2	...
