I am reading and testing the function: incremental backup in qemu-2.5.
But I have serveral questions about it.
1. If I want to start image backup, at first I need to start full mode backup
and then, add a bitmap to trace io, next start incremental backup via the
bitmap before we added. But
device bitmap -- Clear dirty bitmap for
'device'
block_dirty_bitmap_remove device bitmap -- Remove dirty bitmap for
'device'

Add hmp command for incremental backup in drive-backup.
It need a bitmap to backup data from drive-image to incremental image,
so before it need add bitmap for this device to track io.
Usage:
drive_backup [-n] [-f] device target [bitmap] [format]
