namespace DBBackup

{
public partial class Form1 : Form
{

DataTable dtServers = SmoApplication.EnumAvailableSqlServers(true);

private static Server srvr;
ServerConnection conn;
public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)

{
ServerConnection srvConn = new ServerConnection("localhost");
srvConn.LoginSecure = true;
srvr = new Server(srvConn);
foreach (Database dbServer in srvr.Databases)
{
cmbDataBase.Items.Add(dbServer.Name);
}
}

private void btnBrowse_Click(object sender, EventArgs e)

{
FolderBrowserDialog folderBrowserDlg = new FolderBrowserDialog();
folderBrowserDlg.ShowNewFolderButton = false;
DialogResult dlgResult = folderBrowserDlg.ShowDialog();
if (dlgResult.Equals(DialogResult.OK))
{
txtPath.Text = folderBrowserDlg.SelectedPath;
Environment.SpecialFolder rootFolder = folderBrowserDlg.RootFolder;
}
}

private void txtBackup_Click(object sender, EventArgs e)

{
Backup bkp = new Backup();
conn = new ServerConnection();
srvr = new Server(conn);
try
{
string databaseName = cmbDataBase.Text;
bkp.Action = BackupActionType.Database;
bkp.Database = databaseName;
string path;
if (!(txtPath.Text.EndsWith("\\")))
{
path = txtPath.Text + "\\";
}
else
{
path = txtPath.Text;
}

BackupDeviceItem bkpDevice = new BackupDeviceItem(path + databaseName + ".bak", DeviceType.File);

bkp.Devices.Add(bkpDevice);
bkp.Incremental = false;
bkp.SqlBackup(srvr);
MessageBox.Show("Database Backup created successfully");
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
}
}
