Subject: [Qemu-devel] [Questions] Several questions about incremental backup
Date: Mon, 25 Jan 2016 15:35:13 +0800	[thread overview]
Message-ID: <56A5D031.4030409@gmail.com> (raw)

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 when the first incremental backup over, it will
   abdicate the bitmap. How can I start the second incremental backup without
   the bitmap to trace io? I don't know why abdicate the bitmap.
   Is it only an incremental backup?
2. When abdicating the bitmap, it seems leak memory about bitmap->successor.
