From 51ef67270b1d10e1fcf3de7368dccad1ba0bf9d1 Mon Sep 17 00:00:00 2001 From: edison Date: Tue, 21 Sep 2010 19:58:41 -0700 Subject: Copy snapshots out of QCOW2 disk In order to backup snapshots, created from QCOW2 iamge, we want to copy snapshots out of QCOW2 disk to a seperate storage. The following patch adds a new option in "qemu-img": qemu-img convert -f qcow2 -O qcow2 -s snapshot_name src_img bck_img. Right now, it only supports to copy the full snapshot, delta snapshot is on the way. Changes from V1: all the comments from Kevin are addressed: Add read-only checking Fix coding style Change the name from bdrv_snapshot_load to bdrv_snapshot_load_tmp Signed-off-by: Disheng Su Signed-off-by: Kevin Wolf --- qemu-img-cmds.hx | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'qemu-img-cmds.hx') diff --git a/qemu-img-cmds.hx b/qemu-img-cmds.hx index 6d3e5f8e69..6c7176f8b4 100644 --- a/qemu-img-cmds.hx +++ b/qemu-img-cmds.hx @@ -28,9 +28,9 @@ STEXI ETEXI DEF("convert", img_convert, - "convert [-c] [-f fmt] [-O output_fmt] [-o options] filename [filename2 [...]] output_filename") + "convert [-c] [-f fmt] [-O output_fmt] [-o options] [-s snapshot_name] filename [filename2 [...]] output_filename") STEXI -@item convert [-c] [-f @var{fmt}] [-O @var{output_fmt}] [-o @var{options}] @var{filename} [@var{filename2} [...]] @var{output_filename} +@item convert [-c] [-f @var{fmt}] [-O @var{output_fmt}] [-o @var{options}] [-s @var{snapshot_name}] @var{filename} [@var{filename2} [...]] @var{output_filename} ETEXI DEF("info", img_info, -- cgit v1.2.3-55-g7522
