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

2、备份至一个空闲的硬盘

#!/bin/sh

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

LIST="rootfs usr data data2"

for d in $LIST; do

mount /backup/$d

rsync -ax --exclude fstab --delete /$d/ /backup/$d/

umount /backup/$d

done

DAY=`date "+%A"`

rsync -a --delete /usr/local/apache /data2/backups/$DAY

rsync -a --delete /data/solid /data2/backups/$DAY

3、对vger.rutgers.edu的cvs树进行镜像

#!/bin/bash

cd /var/www/cvs/vger/

PATH=/usr/local/bin:/usr/freeware/bin:/usr/bin:/bin

RUN=`lps x | grep rsync | grep -v grep | wc -l`

if [ "$RUN" -gt 0 ]; then

echo already running

exit 1

fi

rsync -az vger.rutgers.edu::cvs/CVSROOT/ChangeLog $HOME/ChangeLog

sum1=`sum $HOME/ChangeLog`

sum2=`sum /var/www/cvs/vger/CVSROOT/ChangeLog`

if [ "$sum1" = "$sum2" ]; then

echo nothing to do

exit 0

fi

rsync -az --delete --force vger.rutgers.edu::cvs/ /var/www/cvs/vger/

exit 0

4、利用find的一种巧妙方式

rsync -avR remote:'`find /home -name "*.[ch]"`' /tmp/

可以用这种方法列出需要备份的文件列表——这种方法似乎比较少人用到。
