Star Wars: Galaxies explains it in much the same way as EVE Online. The majority of NPC and player cities have clone centers, and your clone data is stored whenever you land in a new town or city. When you die, your datapad sends a signal to the clone center to create a new clone of you, complete with all your gear and abilities! Of course, this doesn't explain there are cloning centers everywhere even though the Empire outlawed cloning after the Clone Wars.
Neither does it correlate with consciousness transference being a dark side power.
