个人博客自动备份几天内的项目代码

1、先写个shell脚本

#!/bin/bash
#author: InBi
#date: 2011-07-28
#role: backup files periodically.
#website: http://www.itwhy.org/2011/07-28/707.html

LogFile=/home/lisong/backup/log/`date +"%Y-%m"`.log
DATE=`date +"%Y-%m-%d"`
#DATE=`date -d '1 days ago' "+%Y-%m-%d"`
SourceDir=/home/jiangtao/workspace   //目标代码目录
BakDir=/home/jiangtao/backup/project   //备份后的目录
RetainDay=10   //需要保留几天的备份
ProjectLst=/home/lisong/backup/shdir/project.lst    //目标代码具体目录

if [ ! -f "$LogFile" ]; then
 touch "$LogFile"
fi
if [ ! -w "$LogFile" ]; then
 chmod -R 777 "$LogFile"
fi

echo "backup start at $(date +"%Y-%m-%d %H:%M:%S")" > $LogFile
echo "--------------------------------------------------" >> $LogFile
cd $BakDir
PROJECTLIST=`cat $ProjectLst`
for Project in $PROJECTLIST
do
ProjectData=$SourceDir/$Project
DestDir=$BakDir/$Project
PackFile=$DATE.$Project.tgz
if [ -f $BakDir/$PackFile ]
then
echo "backup file have exist !" >>$LogFile
else
cp -RHpf $ProjectData $DestDir > /dev/null
tar -zcvf $PackFile $Project > /dev/null
echo "backup $Project done into $PackFile ">>$LogFile
rm -rf $Project
fi
OldFile="$BakDir/"$(date --date="$RetainDay days ago" +"%Y-%m-%d").$Project.tgz
if [ -f $OldFile ]
then
rm -f $OldFile > /dev/null
echo "[$OldFile],Delete Old File Success!" >> $LogFile
fi
echo " " >> $LogFile
done
echo "--------------------------------------------------" >> $LogFile
echo "backup end at $(date +"%Y-%m-%d %H:%M:%S")" >> $LogFile
echo " " >> $LogFile
exit 0

2、做个crontab计划任务
