There are four cases:
1) incremental=false, new_image_file not passed:
right now fail; in the future:
- create an image on dest with no backing file;
- writes will be mirrored to current_image_file and dest
- start streaming from current_image_file to dest
2) incremental=false, new_image_file passed:
right now fail; in the future:
- create an image on dest with no backing file;
- live-snapshot based on current_image_file to new_image_file;
- writes will be mirrored to new_image_file and dest
- start streaming from current_image_file to dest
3) incremental=true, new_image_file not passed:
- error
4) incremental=true, new_image_file passed:
- no images will be created
- writes will be mirrored to new_image_file and dest
