軟件介紹

RFDD 類似于UNIX DD工具，用于復(fù)制文件并對(duì)原文件的內(nèi)容進(jìn)行轉(zhuǎn)換和格式化處理，用的比較多的是用來(lái)備份物理硬盤(pán)，并且通過(guò)RFSD服務(wù)，實(shí)現(xiàn)對(duì)遠(yuǎn)程文件的操作。建議在需要時(shí)，對(duì)本地或遠(yuǎn)程物理磁盤(pán)進(jìn)行操作。

軟件功能

支持DD的基本功能
支持?jǐn)帱c(diǎn)續(xù)傳文件
通過(guò)RFSD服務(wù)，實(shí)現(xiàn)對(duì)遠(yuǎn)程設(shè)備文件讀寫(xiě)操作
多平臺(tái)支持 Windows Macosx iPhone iPad Linux Android FreeBSD

如何安裝

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")

安裝路徑

在Linux和Macosx上，默認(rèn)安裝路徑在 /usr/local/bin ，如果需要指定其它路徑，請(qǐng)更改 sh -s 后面的路徑配置。

Windows上，默認(rèn)安裝路徑在 c:\rfdd ，如果需要指定其它路徑，請(qǐng)更改 $rfdd_dir= 后面的路徑配置。

假定rfsd運(yùn)行在192.168.1.1的資源極少的Linux系統(tǒng)上，現(xiàn)在要備份硬盤(pán)數(shù)據(jù)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默認(rèn)512字節(jié)，一次讀取512字節(jié)，讀取速度會(huì)比較慢，所以建議值200k以上。
