远程备份虚拟实验连载（三）

backwang

平台xp sp2 ase12.5
实验目标：远程备份
步骤：
1.假设本地为A，远程为B，启动A的主服务备份服务
2.在A中执行sp_configure "allow remote access",1
3.在A的INI文件中增加B的备份服务器，并执行sp_addserver BACK_B（B的备份服务）
4.然后执行dump database db_name to "/../../xx.data" at BACK_B
5.如果对方有防火墙将会出现以下错误！
request from the Backup Server.
Backup Server: 5.16.2.2: Client-Library error: Error number 4, Layer 5, Origin
3, Severity 5: ct_connect(): network packet layer: internal net library error:
Net-Lib protocol driver call to connect two endpoints failed.
Backup Server: 5.3.2.1: Cannot open a connection to the slave site 'MONKhk_BS'.
Start the remote Backup Server if it is not running.
Msg 8009, Level 16, State 1:
Line 1:
Error encountered by Backup Server.  Please refer to Backup Server messages for
details.
注：如果在没有防火墙并且本地打开了allow remote access，将可以无限制的在远程B上写备份文件，如果有恶意破坏行径者，可以写批处理把B的磁盘占满（）
