I am working on a code to take back up of databse in c#.net 2.0
I am using the following code:

Backup sqlBackup = new Backup();
sqlBackup.Action = BackupActionType.Database;
sqlBackup.BackupSetDescription = "ArchiveDataBase:" +
                                             DateTime.Now.ToShortDateString();
sqlBackup.BackupSetName = "Archive";
sqlBackup.Database = databaseName;
BackupDeviceItem deviceItem = new BackupDeviceItem(destinationPath, DeviceType.File);
ServerConnection connection = new ServerConnection(serverName, userName, password);
Server sqlServer = new Server(connection);
Database db = sqlServer.Databases[databaseName];
sqlBackup.Initialize = true;
sqlBackup.Checksum = true;
sqlBackup.ContinueAfterError = true;
sqlBackup.Devices.Add(deviceItem);
sqlBackup.Incremental = false;
sqlBackup.ExpirationDate = DateTime.Now.AddDays(3);
sqlBackup.LogTruncation = BackupTruncateLogType.Truncate;
sqlBackup.FormatMedia = false;
sqlBackup.SqlBackup(sqlServer);

At the last line of code I am getting Error like: 'Backup failed for Server 'SERVER\SQLEXPRESS'.'
I am not getting what is the problem. Please help me.
I am not using the Sa login for the database.

Edited to add code formatting. Always wrap your code in <pre> tags.

Here's some c# code which will back up your user databases - modify it to your needs:

C#

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Management.Smo;
using Microsoft.SqlServer.Management.Common;
namespace DBBackupCS
{
    class Program
    {
        static void Main(string[] args)
        {
            Server srv = new Server("MyServer\MyInstance");
            ServerConnection srvConn = srv.ConnectionContext;
            srvConn.LoginSecure = true;
            string strBackupDir = srv.Settings.BackupDirectory;
            DatabaseCollection objDatabases = srv.Databases;
            foreach (Database objDB in objDatabases)
            {
                if (objDB.IsSystemObject == false && objDB.IsMirroringEnabled == false)
                {
                    DateTime datNow = DateTime.Now;
                    string strDBName = objDB.Name;
                    string strBKDate = datNow.ToString("yyyyMMddhhmmss");
                    Backup objBackup = new Backup();
                    objBackup.Action = BackupActionType.Database;
                    objBackup.Database = strDBName;
                    objBackup.BackupSetDescription = "Full backup of " + strDBName;
                    objBackup.BackupSetName = strDBName + " Backup";
                    objBackup.MediaDescription = "Disk";
                    objBackup.Devices.AddDevice(strBackupDir + "\\" + strDBName + "_db_" + strBKDate + ".bak", DeviceType.File);
                    objBackup.SqlBackup(srv);
                    if (objDB.DatabaseOptions.RecoveryModel != RecoveryModel.Simple)
                    {
                        datNow = DateTime.Now;
                        string strTBKDate = datNow.ToString("yyyyMMddhhmmss");
                        Backup objTrnBackup = new Backup();
                        objTrnBackup.Action = BackupActionType.Log;
                        objTrnBackup.BackupSetDescription = "Trans Log backup of " + strDBName;
                        objTrnBackup.BackupSetName = strDBName + " Backup";
                        objTrnBackup.Database = strDBName;
                        objTrnBackup.MediaDescription = "Disk";
                        objTrnBackup.Devices.AddDevice(strBackupDir + "\\" + strDBName + "_tlog_" + strTBKDate + ".trn", DeviceType.File);
                        objTrnBackup.SqlBackup(srv);
                   }
                }
            }
        }
    }
}
