增量实时灾备笔记

ssh-keygen -t rsa

这时.ssh目录下会生成私钥和公钥的键值对id_rsa，id_rsa.pub

ssh-copy-id -i /root/.ssh/id_rsa.pub [email protected]

企业文件目录增量实时同步 删除不同步 

wget -O/etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo
yum -y install inotify-tools  rsync

 shell脚本如下：

#!/bin/bash
path1=/srv/salt/base/ldy
ip=192.168.30.13
/usr/bin/inotifywait -mrq --timefmt %y/%m'%d %H:/%M' --format '%T %w%f' -emodify,create,attrib $path1 | while read file;
do
rsync -avz /srv/salt/base/ldy  [email protected]:/root
echo "${file} was rsynced" >> /var/log/rsync.log 2>&1
