怎么实现数据库备份文件的恢复呢？

想实现任意bs端选择数据库备份文件之后，直接运行数据库备份文件，然后恢复数据到数据库服务器中

当前代码如下：【可以实现数据库从服务器备份数据到bs端打开的任意电脑指定目录下】

If FileSys.DirectoryExists("D:\\SQL_Backup") Then \'如果目录C:\\MyFolder存在
  Dim cmd As New SQLCommand
  cmd.C
  Dim time As String =Format(Date.now,"yyyyMMddHHmmss")
  Dim mdf As String = "综合业务系统"
  cmd.CommandText = "use master;BACKUP DATABASE [" & mdf & "] To DISK = \'D:\\SQL_Backup\\" & mdf & "_" & time & ".bak\';"
  cmd.ExecuteNonQuery
 Else
  FileSys.CreateDirectory("D:\\SQL_Backup")
  Dim cmd As New SQLCommand
  cmd.C
  Dim time As String =Format(Date.now,"yyyyMMddHHmmss")
  Dim mdf As String = "综合业务系统"
  cmd.CommandText = "use master;BACKUP DATABASE [" & mdf & "] To DISK = \'D:\\SQL_Backup\\" & mdf & "_" & time & ".bak\';"
  cmd.ExecuteNonQuery
 End If
