今天給大家帶來Linux通過shell腳本怎麼備份係統,Linux通過shell腳本備份係統的步驟,讓您輕鬆解決問題。
在Linux中,備份係統的方法有很多,除了使用備份工具外,還能通過shell備份Linux係統,下麵小編就給大家分享下備份Linux係統的shell腳本。
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 -------------------------------------------- Example $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 “-------------------------------------------- These 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 “----------------------------------------- These 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 “------------------------------------------- These Add_Backup System Files Backup Successfully !”
fi
fi
}
Full_Backup;Add_Backup
上麵就是Linux使用shell腳本備份係統的方法介紹了,通過上麵的腳本就能自動備份係統,但腳本可能還存在不足的地方,可自行改良優化。
以上就是Linux通過shell腳本怎麼備份係統,Linux通過shell腳本備份係統的步驟教程,希望本文中能幫您解決問題。
