用rsync对网站进行镜像备份(3)

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" 

# [e-mail] 

 

# 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。
