elasticsearch 索引备份恢复

备份脚本 es_backup.sh ：

#!/bin/bash
#备份昨天数据，删除30天前索引
host=`hostname`
address="xxx@xxx.com"
es_user=$1
es_passwd=$2
#获取昨天日期(备份使用)
date_yesterday=`date -d "-1 day" +%Y.%m.%d`
#获取当前时间戳
date_now=`date +%s`
#获取一个月前的日期
date_month_ago=`date -d@$[ $date_now - 2592000 ]  "+%Y.%m.%d"`
for  i in txxxx zhaoxxx   #指定备份索引
do
