dateDir=`date +%Y%m`
targetPath="$HOME/$dateDir"
backupName=`date +%Y%m%d`
#

if [ ! -e $targetPath ]
then
mkdir $targetPath
fi
#
#备份文件并压缩,~/date/stu_date.tar.gz
cd $sourcePath && tar -zcvf "$targetPath/stu_$backupName.tar.gz" ./*
#
#记录备份文件列表,~/date/stu_date.log
ls -Rl >> "$targetPath/stu_$backupName.log"
