服务器的还原数据库失败

Question

Using this I successfully back up my database:

Server myServer = new Server(@"PC-1\INSTANCE1");   
private void button1_Click(object sender, EventArgs e)
    {
        try
        {
            if (saveFileDialog1.ShowDialog() == DialogResult.OK)
            {

                Backup bkpDBFull = new Backup();
                bkpDBFull.Action = BackupActionType.Database;
                bkpDBFull.Database = "MyDatabase";
                BackupDeviceItem bkpDevice = new BackupDeviceItem(saveFileDialog1.FileName, DeviceType.File);
                bkpDBFull.Devices.Add(bkpDevice);
                bkpDBFull.BackupSetName = "Sample";
                bkpDBFull.BackupSetDescription = "Sample";
                bkpDBFull.SqlBackup(myServer);
            }
        }
        catch (SmoException ex)
        {
            throw new SmoException(ex.Message, ex.InnerException);
        }
    }

But I got an error in my restore Restore failed for Server 'PC-1\\INSTANCE1'.

    private void button2_Click(object sender, EventArgs e)
    {
        if (openFileDialog1.ShowDialog() == DialogResult.OK)
        {
            Restore restoreDB = new Restore();
            restoreDB.Database = "MyDatabase";
            restoreDB.Action = RestoreActionType.Database;
            BackupDeviceItem bkpDevice = new BackupDeviceItem(openFileDialog1.FileName, DeviceType.File);
            restoreDB.Devices.Add(bkpDevice);
            restoreDB.ReplaceDatabase = true;
            restoreDB.SqlRestore(myServer);
        }
    }

I use the same server in both backup and restore. Why it failed in restore although the backup is successful using the same server and database?

Answer 1

One thing to rule out is it not liking the hyphen in the machine name, which you're not supposed to do really. If you try using the IP address as the server name this should rule this out.

More likely to be a database in use thing as others have said.
