Q：绑定端口873失败是怎么回事？

    　A：如果你不是以root权限运行这一守护进程的话，因为1024端口以下是特权端口，会出现这样的错误。你可以用–port参数来改变。

    　Q：为什么我认证失败？

    　A：从你的命令行看来：

    　你用的是：

    　> bash$ rsync -a 144.16.251.213::test test

    　> Password:

    　> @ERROR: auth failed on module test

    　>

    　> I dont understand this. Can somebody explain as to how to acomplish this.

    　> All suggestions are welcome.

    　应该是没有以你的用户名登陆导致的问题，试试rsync -a max@144.16.251.213::test test

    　四、一些可借鉴的脚本

    　这里这些脚本都是rsync网站上的例子：

    　1、每隔七天将数据往中心服务器做增量备份

    　#!/bin/sh

    　# This script does personal backups to a rsync backup server. You will end up

    　# with a 7 day rotating incremental backup. The incrementals will go

    　# into subdirectories named after the day of the week, and the current

    　# full backup goes into a directory called "current"

    　# tridge@linuxcare.com

    　# directory to backup

    　BDIR=/home/$USER

    　# excludes file – this contains a wildcard pattern per line of files to exclude

    　EXCLUDES=$HOME/cron/excludes

    　# the name of the backup machine

    　BSERVER=owl

    　# your password on the backup server

    　export RSYNC_PASSWORD=XXXXXX

　########################################################################

    　BACKUPDIR=`date +%A`

    　OPTS="–force –ignore-errors –delete-excluded –exclude-from=$EXCLUDES

    　–delete –backup –backup-dir=/$BACKUPDIR -a"

    　export PATH=$PATH:/bin:/usr/bin:/usr/local/bin

    　# the following line clears the last weeks incremental directory

    　[ -d $HOME/emptydir ] || mkdir $HOME/emptydir

    　rsync –delete -a $HOME/emptydir/ $BSERVER::$USER/$BACKUPDIR/

    　rmdir $HOME/emptydir

    　# now the actual transfer

    　rsync $OPTS $BDIR $BSERVER::$USER/current
