windows文件备份到linux：windows定时任务+cwrsync+ssh免密码认证

一、安装cwrsync

二、创建密钥对，实现ssh免密码验证

linux服务器上

[[email protected] ~]# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 　　　　　　###回车
Created directory ‘/root/.ssh‘.
Enter passphrase (empty for no passphrase):
Enter same passphrase again: 　　　　　　　　###回车
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:　　　　　　####回车
fc:68:38:67:fd:d4:7f:3b:e7:67:93:ed:e2:c0:a9:25 [email protected]
The key‘s randomart image is:
+--[ RSA 2048]----+
|                 |
|                 |
|                 |
|       .         |
|        S        |
|       . + . o   |
|      o = E * . o|
|       =   * ..=*|
|          . ...*@|
+-----------------+

[[email protected] ~]# ssh-copy-id [email protected]The authenticity of host ‘localhost (::1)‘ can‘t be established.ECDSA key fingerprint is e5:07:2a:f0:9f:c5:df:64:70:61:6a:7a:31:bf:21:7a.Are you sure you want to continue connecting (yes/no)? yes/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys[email protected]‘s password: 

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh ‘[email protected]‘"and check to make sure that only the key(s) you wanted were added.

[[email protected] ~]# ls .ssh/authorized_keys  id_rsa  id_rsa.pub  known_hosts###########将id_rsa下载到本地

三、编辑远程copy脚本

 SETLOCAL
 SET CWRSYNCHOME=D:\cwRsync　　　　####cwrsync安装路径
 SET HOME=D:\cwRsync　　　　　　######服务器密钥rd_rsa路径，我的路径为D:\cwRsync\.ssh
 SET CWOLDPATH=%PATH%
 SET PATH=%CWRSYNCHOME%\BIN;%PATH% cd D:\cwRsync\bin rsync -avz --delete /cygdrive/d/test [email protected]:/tmp    ######/cygdrive是路径格式，我的实际路径为d:/test。#########首次运行脚本需要手动输入一次密码########

四、定时运行

• 创建基本任务

• 创建触发器，任务执行条件

• 具体执行时间

• 触发条件后需要做哪些操作

• 如果是打开程序，运行脚本，请选择程序、脚本路径
