手工备份Xen HVM VPS

ssh登录服务器
运行 lvscan 扫描LV存储a

[root@vs09 /]# lvscan
ACTIVE ‘/dev/vol/vm3240_img’ [20.00 GB] inherit
ACTIVE ‘/dev/vol/vm3260_img’ [25.00 GB] inherit
ACTIVE ‘/dev/vol/vm3280_img’ [20.00 GB] inherit
ACTIVE ‘/dev/vol/vm3290_img’ [20.00 GB] inherit
ACTIVE ‘/dev/vol/vm3320_img’ [20.00 GB] inherit
ACTIVE ‘/dev/vol/vm3330_img’ [20.00 GB] inherit
ACTIVE ‘/dev/vol/vm3360_img’ [20.00 GB] inherit
ACTIVE ‘/dev/vol/vm3370_img’ [20.00 GB] inherit

建立Snapshot/快照

[root@vs09 /]#
lvcreate -s -L 10G -n vm3240_img-snap /dev/vol/vm3240_img
Logical volume “vm3240_img-snap” created

参数意思
-s = 快照模式
-L *G/M = 快照大小
-n xxx = 快照名称
/dev/vol/vm324_img 原镜像

重建分区表 (如果不需要挂载检查数据 不需要重建)
kpartx -av /dev/vol/vm3240_img-snap
add map vm324_img-snap1 : 0 62910477 linear /dev/vol/vm3240_img-snap 63

挂载NTFS文件系统 获得硬盘数据
mount -t ntfs /dev/mapper/vm3240_img-snap1 /mnt -o force

The disk contains an unclean file system (0, 0).
The file system wasn’t safely closed on Windows. Fixing.
可以查看数据
[root@vs09 /]# ll /mnt
