I usually leave my staves outside in the garage with the bark off for a couple of weeks if I think they will check on the back (still sealing the ends, as those will check no matter what), in the cold weather. That'll slow down evaporation. Also, half-rounds have a greater chance of checking than quarters, due to the greater surface area of the back versus the mass of the stave. Bringing a freshly debarked half-round stave inside a warm, dry house is pretty risky, even if the ends are sealed.
In warmer weather, not much you can do but seal the back as well. Most of my staves are black locust and buckthorn cut in the winter (buckthorn bark is easy to remove year-round), so I haven't had to deal with warm weather checking.
