Do you have to add a subfloor to subfloor of a bathroom before adding backer board?

Not usually, no. As long as the sub floor is solid, without water damage, etc then a backer board is usually plenty. You need to have 1 1/4" of sub floor and backer board when you put the tile down. Generally speaking, homes are built with at least a 3/4" sub floor and 1/4" cement backer board with 1/4" x 1/4" trowel of thinset equals this. If you are not sure, don't assume. Find a vent in the floor. Pull out the register vent and use a hand mirror to see the sub floor. Take a tape measure and measure its thickness.

If you are talking about a fiber cement backer board, the manufacturer of the board should provide the answer you are after. I am currently using Hardiplank to reside my house, and the manufacturer recommends attacheing the TyVek house wrap to the wood sheathing per TyVeks recommended process. Hope this helps.
