Mysql数据备份以及异地存储

整理tuscany.org.cn的服务器，发现3年前写的脚本还在跑着 :)
脚本如下：
#==========================================================
#!/bin/bash
current_date=`date +%Y-%m-%d:%H:%M:%S`
/usr/local/mysql/bin/mysqldump -prootpass  dbname1 > ./DB_DIR/dbname1_"$current_date"_dump_file.sql 
/usr/local/mysql/bin/mysqldump -prootpass  dbname2 > ./DB_DIR/dbname2_"$current_date"_dump_file.sql
scp /root/DB_DIR/dbname1_"$current_date"_dump_file.sql sca@172.90.91.92:/root/DBBakDir
scp /root/DB_DIR/dbname2_"$current_date"_dump_file.sql sca@172.91.92.93:/root/DBBakDir
if [ $? -ne 0 ]
then
mail -s "Warning mesage from the automating backup program of tuscany.org.cn" wanghongwei@myce.net.cn < mailcontext.txt
fi
