###上面为备份MySQL数据库，如果在前面加了Backup_Database_Name5=yourdatabasename，则再加/usr/local/mysql/bin/mysqldump -u$MYSQL_UserName -p$MYSQL_PassWord $Backup_Database_Name5 > /home/backup/db-$Backup_Database_Name5-$(date +"%Y%m%d").sql 。如果多余则删除多余行。
rm $OldWWWBackup
rm $OldDBBackup
###删除3天前的备份###
cd /home/backup/
###下面为自动上传部分，不得不说lftp很强大，抛弃ftp吧####
lftp $FTP_HostName -u $FTP_UserName,$FTP_PassWord << EOF
cd $FTP_BackupDir
mrm $OldWWWBackup
mrm $OldDBBackup
mput $TodayWWWBackup
mput $TodayDBBackup
bye
EOF
