RFDD

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服务器,实现对远程文件的操作。建议在有需要时,对本地或远程物理磁盘进行操作。

版本: 1.1.3.419 更新: 2018-10-10
功能特性
  • 支持DD的基本功能
  • 支持断点续传文件
  • 通过RFSD,实现远程设备的文件操作
  • 多平台支持 Windows Macosx iPhone iPad Linux Android

usage: rfdd [if=FILE] [of=FILE] [ibs=N] [obs=N] [bs=N] [count=N] [skip=N]
[seek=N] conv=[notrunc|noerror|sync|fsync|resume] retry=NUM
status=[noxfer|none] level=[LEVEL]
	bs=BYTES    read and write BYTES bytes at a time
	ibs=N       Read N bytes at a time
	obs=N       Write N bytes at a time
	count=N     copy only N input blocksn
	seek=BLOCKS skip BLOCKS obs-sized blocks at start of output
	skip=BLOCKS skip BLOCKS ibs-sized blocks at start of input
	if=FILE     read from FILE instead of stdin
	of=FILE     write to FILE instead of stdout
	conv=CONVS  [notrunc,noerror,sync,fsync,swab,resume,]
	conv=notrunc   Don't truncate output file
	conv=noerror   Continue after read errors
	conv=sync      Pad blocks with zeros
	conv=fsync     Physically write data out before finishing
	conv=swab      Swap every pair of bytes
	conv=resume    Continue writing at the end of the output file
	iflag=skip_bytes skip=N is in bytes
	oflag=seek_bytes seek=N is in bytes
	retry=NUM      Retry request NUM times if transient problems occur
	status=noxfer  Suppress rate output
	status=none    Suppress all output
	level=LEVEL    set log level: [verb, dbg, info, warn, err]

使用例子

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。
