freebsd rsync 数据镜像备份-Ppabc运维日志

前言
rsync是Linux系统下的数据镜像备份工具，从软件的命名上就可以看出来了——remote sync。rsync支持大多数的类Unix系统，无论是Linux、Solaris还是BSD上都经过了良好的测试。rsync的最新版本可以从 http://rsync.samba.org/rsync/获得。它的特性如下：
1、可以镜像保存整个目录树和文件系统。
2、可以很容易做到保持原来文件的权限、时间、软硬链接等等。
3、无须特殊权限即可安装。
4、优化的流程，文件传输效率高。
5、可以使用rcp、ssh等方式来传输文件，当然也可以通过直接的socket连接。

本文介绍了如何使用rsync服务从Linux到Windows和linux进行远程备份
软件及平台
FreeBSD 5.2 (Server and Client)
Server IP:192.168.83.80 Hostname: freebsd-1
Client IP:192.168.83.81 Hostname: freebsd-2
apache_1.3.29
rsync-2.5.7
目的/etc/rsyncd.conf

备份Rsync Server(192.168.83.80)上的 /usr/local/apache2/htdocs 目录下所有内容,到Rsync Client(192.168.83.81)的/backup/www 下
安装及配置
一,Rsync Server
Step 1: 安装
freebsd-1#cd /usr/ports/net/rsync
freebsd-1#make install clean .
Step 3: 配置rsyncd.conf
freebsd-1#vi /usr/local/etc/rsyncd.conf //加入以下内容
[www]
comment = web server backup
path = /usr/local/apache2/htdocs
auth users = tonny
uid = nobody
gid = nogroup
secrets file = /usr/local/etc/rsyncd.secrets
read only = no

cat /etc/rsyncd.conf
