對于如何在windows系統(tǒng)上面怎么進行系統(tǒng)備份相信大家都知道,那么大家知道linux通過shell腳本怎么備份系統(tǒng)嗎?小編分享了Linux通過shell腳本備份系統(tǒng)的方法，希望對大家有所幫助。

Linux通過shell腳本備份系統(tǒng)方法

腳本如下：

#!/bin/sh

#Automatic Backup Linux System Files

#Author wugk 2013-11-22

#Define Variable

SOURCE_DIR=(

$*

)

TARGET_DIR=/data/backup/

YEAR=`date +%Y`

MONTH=`date +%m`

DAY=`date +%d`

WEEK=`date +%u`

FILES=system_backup.tgz

CODE=$?

if

[ -z “$*” ];then

echo -e “Please Enter Your Backup Files or Directories/n--------------------------------------------/nExample $0 /boot /etc 。。。。。。”

exit

fi

#Determine Whether the Target Directory Exists

if

[ ! -d $TARGET_DIR/$YEAR/$MONTH/$DAY ];then

mkdir -p $TARGET_DIR/$YEAR/$MONTH/$DAY

echo “This $TARGET_DIR is Created Successfully !”

fi

#EXEC Full_Backup Function Command

Full_Backup()

{

if

[ “$WEEK” -eq “7” ];then

rm -rf $TARGET_DIR/snapshot

cd $TARGET_DIR/$YEAR/$MONTH/$DAY ;tar -g $TARGET_DIR/snapshot -czvf $FILES `echo ${SOURCE_DIR[@]}`

[ “$CODE” == “0” ]&&echo -e “--------------------------------------------/nThese Full_Backup System Files Backup Successfully !”

fi

}

#Perform incremental BACKUP Function Command

Add_Backup()

{

cd $TARGET_DIR/$YEAR/$MONTH/$DAY ;

if

[ -f $TARGET_DIR/$YEAR/$MONTH/$DAY/$FILES ];then

read -p “These $FILES Already Exists， overwrite confirmation yes or no ? ： ” SURE

if [ $SURE == “no” -o $SURE == “n” ];then

sleep 1 ;exit 0

fi

#Add_Backup Files System

if

[ $WEEK -ne “7” ];then

cd $TARGET_DIR/$YEAR/$MONTH/$DAY ;tar -g $TARGET_DIR/snapshot -czvf $$_$FILES `echo ${SOURCE_DIR[@]}`

[ “$CODE” == “0” ]&&echo -e “-----------------------------------------/nThese Add_Backup System Files Backup Successfully !”

fi

else

if

[ $WEEK -ne “7” ];then

cd $TARGET_DIR/$YEAR/$MONTH/$DAY ;tar -g $TARGET_DIR/snapshot -czvf $FILES `echo ${SOURCE_DIR[@]}`

[ “$CODE” == “0” ]&&echo -e “-------------------------------------------/nThese Add_Backup System Files Backup Successfully !”

fi

fi

}

Full_Backup;Add_Backup

上面就是Linux使用shell腳本備份系統(tǒng)的方法介紹了，通過上面的腳本就能自動備份系統(tǒng)，但腳本可能還存在不足的地方，可自行改良優(yōu)化。
