There are now two kinds of pausing: a Vacation Pause, where you know you will be coming back to the character at a specific time, and a Cold Storage pause, where you are putting the character on ice indefinitely.
With the former, you keep (IIRC) guild memberships, bonds, unique items, and Marshalships.
With the latter, you lose pretty much everything but your character's stats, common items, and gold on hand.
