SQLDMO(SQL Distributed Management ObjectsSQL分布式管理对象)封装了Microsoft SQL Server数据库中对象SQLDMO是Microsoft SQL Server中企业管理器所使用应用接口所以它可以执行很多功能其中当然也包括对数据库备份和恢复

　　SQLDMO由Microsoft SQL Server自带SQLDMO.dll提供由于SQLDMO.dll是个COM对象所以大家在用的前必须在.NET项目中添加对它引用

　　下面是用C#语言书写用于Microsoft SQL Server数据库备份和恢复类:

using ;
DbService
{
/// <summary>
/// DbOper类,主要应用SQLDMO实现对Microsoft SQL Server数据库备份和恢复
/// </summary>
public sealed DbOper
{
/// <summary>
/// DbOper类构造
/// </summary>
private DbOper
{
}
/// <summary>
/// 数据库备份
/// </summary>
public void DbBackup
{
SQLDMO.Backup oBackup = SQLDMO.BackupClass;
SQLDMO.SQLServer oSQLServer = SQLDMO.SQLServerClass;
try
{
oSQLServer.LoginSecure = false;
oSQLServer.Connect("localhost", "sa", "1234");
oBackup.Action = SQLDMO.SQLDMO_BACKUP_TYPE.SQLDMOBackup_Database;
oBackup.Database = "Northwind";
oBackup.Files = @"d:Northwind.bak";
oBackup.BackupSetName = "Northwind";
oBackup.BackupSetDescription = "数据库备份";
oBackup.Initialize = true;
oBackup.SQLBackup(oSQLServer);
}
catch
{
throw;
}
finally
{
oSQLServer.DisConnect;
}
}
/// <summary>
/// 数据库恢复
/// </summary>
public void DbRestore
{
SQLDMO.Restore oRestore = SQLDMO.RestoreClass;
SQLDMO.SQLServer oSQLServer = SQLDMO.SQLServerClass;
try
{
oSQLServer.LoginSecure = false;
oSQLServer.Connect("localhost", "sa", "1234");
oRestore.Action = SQLDMO.SQLDMO_RESTORE_TYPE.SQLDMORestore_Database;
oRestore.Database = "Northwind";
oRestore.Files = @"d:Northwind.bak";
oRestore.FileNumber = 1;
oRestore.ReplaceDatabase = true;
oRestore.SQLRestore(oSQLServer);
}
catch
{
throw;
}
finally
{
oSQLServer.DisConnect;
}
}
}
}

　　这段代码虽然很短但是却很实用希望能够对大家有所帮助:)
