zroot mirror: resilvering disk1 -> disk0

Dear *,

I am having quite an idiotic setup probably most people would say but I use an external USB HDD (disk1) for mirroring my EEEPC's HDD (disk0) and I was thinking what is the procedure to do the resilvering from disk1 to disk0, my external USB mirror disk is attached from time to time only for backing up purposes.

Maybe you know if there is a way of swapping device names and do opposite resilvering? Or I must use replace command? Or I use mirror functionality not for its purpose? (these both HDDs are identical).

Many Thanks,
ekar
