Docker Checkpoint

I wanted to make an evaluation of the state of the checkpoint support in docker but details are very scanty.
How is the checkpoint support in docker so far. I mean would checkpointing a container with open file handles, socket handles, open devices and so on be supported?
I tried looking for information on this topic but so far details are far in between.

what do you mean by checkpoint? what do you want to accomplish?

Checkpoint

I want to save the state of my applications and resume them to another server, container etc…
