Question

I need to backup (using C#) a SQL 2005 Database to a *.bak file. From that file, I am trying to restore into a new Database on the same exact server.

The backup works fine and then my C# code calls the restore method and it appears to be working until it finally “timesout”. I checked the “innerExceptions” and they reveal that the RESTORE made it to 90 percent and then returns the exception.

Below is the code I am using to BACKUP AND RESTORE.

Can someone please let me know where I am going wrong? It must be a timeout parameter somewhere that I can set but I do not know what it is or how to do it.

public class JRBackupRestoreDB
{
    public static void BackupDatabase(String databaseName, String userName, String password, String serverName, String destinationPath)
    {
        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);
    }

    public static void RestoreDatabase(String databaseName, String filePath,
    String serverName, String userName, String password,
    String dataFilePath, String logFilePath)
    {
        Restore sqlRestore = new Restore();

        BackupDeviceItem deviceItem = new BackupDeviceItem(filePath, DeviceType.File);
        sqlRestore.Devices.Add(deviceItem);
        sqlRestore.Database = databaseName;

        ServerConnection connection = new ServerConnection(serverName, userName, password);
        Server sqlServer = new Server(connection);

        Database db = sqlServer.Databases[databaseName];
        sqlRestore.Action = RestoreActionType.Database;
        String dataFileLocation = dataFilePath + databaseName + ".mdf";
        String logFileLocation = logFilePath + databaseName + "_Log.ldf";
        db = sqlServer.Databases[databaseName];
        RelocateFile rf = new RelocateFile(databaseName, dataFileLocation);

        System.Data.DataTable logicalRestoreFiles = sqlRestore.ReadFileList(sqlServer);
        sqlRestore.RelocateFiles.Add(new RelocateFile(logicalRestoreFiles.Rows[0][0].ToString(), dataFileLocation));
        sqlRestore.RelocateFiles.Add(new RelocateFile(logicalRestoreFiles.Rows[1][0].ToString(), logFileLocation));

        sqlRestore.SqlRestore(sqlServer);
        db = sqlServer.Databases[databaseName];
        db.SetOnline();
        sqlServer.Refresh();
    }

}

Have you tried setting a value with ServerConnection.StatementTimeout to see what happens?
