One of these nice DNS resolvers that can store and load the cache is 
.... drumroll... Unbound!

Usage:    unbound-control [options] command
     Remote control utility for unbound server.
[...]
   dump_cache            print cache to stdout
   load_cache            load cache from stdin
[...]

However that is not done automatically, you need to tweak your startscript.
