對於如何在Windows系統上面怎麼進行系統備份相信大家都知道,那麼大家知道Linux通過shell腳本怎麼備份系統嗎?學習啦小編分享了Linux通過shell腳本備份系統的方法，希望對大家有所幫助。
Linux通過shell腳本備份系統方法
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腳本備份系統的方法介紹了，通過上面的腳本就能自動備份系統，但腳本可能還存在不足的地方，可自行改良優化。
