Linux通过shell脚本备份系统的方法
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,今天华军小编给大家展示的是Linux通过shell脚本备份系统的方法,精心挑选的内容希望大家多多支持、多多分享,喜欢就赶紧get哦!。 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 上面就是小编总结的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。
