  在Linux中,备份系统的方法有很多,除了使用备份工具外,还能通过shell备份Linux系统,下面小编就给大家分享下备份Linux系统的shell脚本。  Linux通过shell脚本备份系统的方法   脚本如下:   #!/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脚本备份系统的方法介绍了,通过上面的脚本就能自动备份系统,但脚本可能还存在不足的地方,可自行改良优化。
