How many entity attributes should been saved so that next time when I load it from server, It is at same position, direction, and scale in world space

If you want something at same position, then you should save position. Likewise for any other fundamental properties, such as velocity.

[RossNordby]

Pretty much- what you should save depends on what you care to persist. Position, orientation, linear velocity, and angular velocity covers kinematic state. Could store a shape id or something to disk to reconstruct/load the entity's shape. Dynamic bodies would need mass/inertia too.

thanks a lot of RossNordby's suggestion
