Subject: [Qemu-devel] snapshot vs COW?
Date: Fri, 12 Dec 2008 12:17:14 +0900	[thread overview]
Message-ID: <fdaac4d50812111917n47c27f5atf36b81f7c40c620e@mail.gmail.com> (raw)

Hi,

>From what I see, both snapshot and COW features can be used to try
some changes on the file image before we the change back to the
original image.

But what is the advantages of snapshot over COW, and in which case we
should use snapshot, but not COW? Vice verse, when COW is more
appropriate?

Many thanks,
Jun
