mysqlのbinlogログの自動パッケージング

一、需要
オンラインの1台の機械はrsyncをして、5台のmysql機械からbinlogログをローカルに引き出して、前は手動でパッケージして、今スクリプトを書いて、crontabに置いて定期的にパッケージを実行して、そしてパッケージしたファイルを削除します.
二、脚本は以下の通り

#!/bin/sh
# usage: 
# nohup sh /tmp/backup_binlog_tar.sh > nohup.out  2>/dev/null  &


dir_backup_tar="/data0/backup_log-bin_tar"_`date +%Y-%m-%d--%H-%M-%S`
echo $dir_backup_tar
mkdir -p $dir_backup_tar

# usage: 
# nohup sh /tmp/backup_binlog_tar.sh > nohup.out  2>/dev/null  &
