rsync+sersync | 易学教程

rsync是linux系统下的数据镜像备份工具。使用快速增量备份工具Remote Sync可以远程同步，支持本地复制，或者与其他SSH、rsync主机同步

sersync可以记录下被监听目录中发生变化的（包括增加、删除、修改）具体某一个文件或者某一个目录的名字，然后使用rsync同步的时候，只同步发生变化的文件或者目录

实验环境

centos6.5_x64

192.168.10.18 rsync+sersync rsync1

192.168.10.15 rsync rsync2

实验软件

sersync2.5.4_64bit_binary_stable_final.tar.gz
