无法打开备份设备“\\Servername\backup$\Database\databasename.bak”。操作系统错误 53（找不到网络路径。）
Cannot open backup device '\\Servername\backup$\Database\databasename.bak'. Operating system error 53(The network path was not found.)
我用过
Microsoft SQL Server 2012 (SP3) (KB3072779) - 11.0.6020.0 (X64)
Standard Edition (64-bit) on Windows NT 6.1 (Build 7601: Service Pack 1)
1)I have an Maintenance Plan, which backup sql database in a network share.
2) Backup execute every day in 17:00
3) Sql server services and SQL Agent services running domain accounts
Domain\SQLServer
4) Remote Network share : \Servername\backup$\Database\databasename.bak
5) Network path "backup$" have a full rights domain accounts
Domain\SQLServer and path "Database" have a full rights domain accounts
Domain\SQLServer.
6) But i get this error
Cannot open backup device '\Servername\backup$\Database\databasename.bak'. Operating system error 53(The network path was not found.).
7) I can't understand what could be the problem.
8) I noticed one interesting moment. When i forced update sql server in a sql management studio and run manually maintenance plan, backup run success and databasename.bak appears on remote network share, but when i start maintenance plan automatically, plan success work 2-3 days but then history again Cannot open backup device '\Servername\backup$\Database\databasename.bak'. Operating system error 53(The network path was not found.). I have no idea what it could be.
大家好，我已经解决了这个问题。
问题出在 Kaspersky Endpoint Security 10 中。我已经停止模块 "protection from network attacks" 并且备份成功到远程网络共享并且 "lanman service" 工作正常。感谢您的 wireshark。模块 "protection from network attacks" 以某种方式阻止了正常工作的 lanman 服务并阻止了使用 lanman 服务的 445 端口。
