From Dan Wood of the Orange County Register:
A scheduling challenge that NHL players, coaches and observers viewed as a tremendous disadvantage not so long ago has become nothing more than a necessary evil, with the less thought given to it, the better.
It used to be that when a team had to play a second game in two nights, against a fresh opponent, the “tired” team was considered to be in a huge hole. In today’s NHL, however, a large percentage of games feature exactly that scenario.
The Ducks, for example, will play 18 sets of back-to-back games this season, and on only two occasions will their second-night opponent also have played the night before. Seventeen times, meanwhile, the Ducks will face a club that has played the night before, with the Ducks also on the second night of a back-to-back in two of those instances.

As Wood states, unless you lessen the number of games per season (no chance because it cuts into revenue) then back-to-backs will continue to be as prevelant as they are now.
