When a page is deleted, it is just flagged as deleted, not completely removed from the database. And project admins are able to view deleted pages (and restore them too). If you try it out you should be able to see how it works.

If a page is deleted, where would it's link be stored?
I mean, if a page is deleted, is there any place its copy would be stored?
