Rsync 同步备份服务器重要配置文件

步骤：

1.确定备份目标服务器list 

2.确定备份目标文件路径

3.制订备份策略

4.搭建rsync server

5.生成执行备份脚本

6.saltstack分发脚本到备份目标服务器

7.saltstack批量配置cron计划任务到备份目标服务器

8.在rsync server配置cron计划任务定时生成tar包存储到指定路径

 

一、确定备份目标服务器list

　　PMC PMS LS

二、确定备份目标文件路径

　　/etc/lis　　/etc/logstash　　/lib/systemd/system

三、备份策略

　　每天23点同步备份到rsync server

　　每天23：:50 rsync server 打包备份文件 转移到目录 /opt/backup_tar/ 下
