The bumps are either projected file textures or 2d procedurals or 3d procedural textures. To ensure the relationship between the projections transofmations and the spheres are maintained you can simply parent the texture transform nodes to your sphere for a simple solution.

However this will not work for deformations unless you create a texture reference object or bake the textures out as 2d files and add those to your shader in place of the 3d procedurals.
