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

cd $TARGET_DIR/$YEAR/$MONTH/$DAY ;

if

[ -f $TARGET_DIR/$YEAR/$MONTH/$DAY/$FILES ];then

[ “$CODE” == “0” ]&&echo -e “-----------------------------------------\nThese Add_Backup System Files Backup Successfully !”

fi

else

if

[ $WEEK -ne “7” ];then
