Well, they're just files on disk. You can freely copy the index files around wherever you want. I'd do a few practice runs first though. So: 1> unload the core (or otherwise shut it down). 2> copy the data directory and all sub directories. 3> I'd also copy the conf directory to insure a consistent picture of the index when you restored it. 4> delete the core however you please.
Of course before I did <4> I'd try bringing up the core on some other machine a few times, just to be sure you had all the necessary parts... Once you were confident of the process you don't need to restore _every_ time.
