软件介绍

RFDD 类似于UNIX DD工具，用于复制文件并对原文件的内容进行转换和格式化处理，用的比较多的是用来备份物理硬盘，并且通过RFSD服务，实现对远程文件的操作。建议在需要时，对本地或远程物理磁盘进行操作。

软件功能

支持DD的基本功能

支持断点续传文件

通过RFSD服务，实现对远程设备文件读写操作

多平台支持 Windows Macosx iPhone iPad Linux Android FreeBSD

如何安装

使用curl

curl http://ranfs.com/pub/rfdd/all/get.sh -o -|sh -s /usr/local/bin

使用wget

wget http://ranfs.com/pub/rfdd/all/get.sh -O -|sh -s /usr/local/bin

使用powershell

$rfdd_dir="c:\rfdd";Invoke-Expression(New-Object Net.WebClient).DownloadString("http://ranfs.com/pub/rfdd/all/get.ps1")

安装路径

在Linux和Macosx上，默认安装路径在 /usr/local/bin ，如果需要指定其它路径，请更改 sh -s 后面的路径配置。

Windows上，默认安装路径在 c:\rfdd ，如果需要指定其它路径，请更改 $rfdd_dir= 后面的路径配置。

假定rfsd运行在192.168.1.1的资源极少的Linux系统上，现在要备份硬盘数据本地的windows d:\1.img

rfdd if=rfp://192.168.1.1/dev/sda of=d:\1.img bs=512k

注意：bs默认512字节，一次读取512字节，读取速度会比较慢，所以建议值200k以上。
