[administrative][archlinux][clonezilla][disk cloning] 一块 windows 10 硬盘的备份
https://wiki.archlinux.org/index.php/disk_cloning
https://wiki.archlinux.org/index.php/full_system_backup_with_rsync
https://en.wikipedia.org/wiki/Comparison_of_disk_cloning_software
一个软件：

说白了，从技术上来讲，备份一块硬盘就两个途径。1 section to section 2. block to block
一，就是扇区到扇区备份：
这种方式，就是dd就好了，1T的备份出来就是1T，当然稍微聪明一点的方式就是gzip压缩一下，也许1T可以变成800G？ 我不知道。
二，就是块到块备份：
这是一个比较聪明的方法，因为程序可以知道，哪个块是空的，哪个块是用了的。所以，实际上，只需要把用了的块备份出来就可以了。
也就是说，一块1T的硬盘，我只写了1G的数据，理论上也就备份1点多个G的数据出来就够了。
但这个前提是软件要认识文件系统。以及各种分区表，巴拉吧啦之类的。
这样的软件有：
ghost https://www.symantec.com/products/endpoint-hybrid-cloud-security/endpoint-management/ghost-solutions-suite
True Image http://www.acronis.com/zh-cn/personal/computer-backup/
他们都很好，他们都是收！费！达！
最后一个，我呕心沥血终于找到的，免费又好用，还是GPL：

三， 安装clonezilla U盘启动
1. 下载zip格式的软件。
http://clonezilla.org/downloads/download.php?branch=stable
2. 根据文档 method B 安装
http://clonezilla.org/liveusb.php
a. 分区
(parted) mkpart primary 1MiB 1GiB (parted) mkpart primary 1GiB 100%
b. 创建文件系统
/home/tong/ISO [tong@T7] [20:07] > sudo mkfs.vfat -F 32 /dev/sdc1 # 这个地方是错的，见下文。正确应该用fat而不是vfat mkfs.fat 4.1 (2017-01-24) /home/tong/ISO [tong@T7] [20:07] > sudo mkfs.ntfs /dev/sdc2
c. 安装（先挂载起来）
/home/tong/ISO [tong@T7] [20:26] > unzip clonezilla-live-2.5.0-25-amd64.zip -d /run/media/tong/CentOS\ 7\ x86_64
/run/media/tong/CentOS 7 x86_64/utils/linux [tong@T7] [20:31] > sudo pacman -S syslinux
报错

四：
MD，大半夜的脑子进水选错了分区。。。成功。

卸掉 syslinux 和mtools 再试。
依然成功！
update @2017-06-06
并不能启动。经过验证排查怀疑问题如下：
1. sudo mkfs.vfat -F 32 /dev/sdc1 用了vfat而不是fat，不能启动。
2. 还用了ntfs分区，同样也不能启动。
3. 正确的用法是严格按照文档中的命令，sudo mkfs.fat -F 32 /dev/sdc1
至此，U盘可以正确启动了。全是图像界面，按照提示，很易用。不做赘述。
update @2017-06-10
镜像的时候可以选择工具，选了partclone，结果报错。
最后选了ntfsclone，保存成功。我是说应该成功了。。。。因为它打印成功了，但是在最后进行完整性检查的时候，说不能检测，因为不是partclone。
一共生成一个文件夹，12G。
