title: How to restore the sharepoint list data after deploying project solution again?
body: <p>I have an Visual Studio 2010 empty sharepoint solution project. Solutions consist of several custom lists and workflows attached to that lists. The solution always changes, so it means I'm redeploying the solution very often. After deploying it deletes all of the content from the existed lists and recreates that lists again. Now I'm considering the ways how to solve the problem of disappearing of the data, are there effective ways?</p>
  
  <p>p.s. I cannot use lists created in UI, because I need custom defined lists.</p>
