The restore backup do nothing

When that most important working code in the restoreBackup was commented?

function restoreBackup() {
        var txtBackupFilePath = $("#txtBackupFilePath");
        if (txtBackupFilePath.hasClass("initial") || txtBackupFilePath.val().trim().length == 0) {
                InfoTip.alertI18n("message_selectBackupFile");
                txtBackupFilePath.focus();
                return;
        }
        var backupFilePath = txtBackupFilePath.val();
        var backupData = undefined;

        if (backupFilePath.substr(0, 7) == "http://" || backupFilePath.substr(0, 8) == "https://") {
                $.ajax({
                        async: false,
                        url: backupFilePath,
                        success: function(data, textStatus){
                                if (data.length <= 1024 * 50) // bigger than 50 KB
                                        backupData = data;
                                else
                                        Logger.log("Too big backup file!", Logger.Types.error);
                        },
                        error: function(request, textStatus, thrownError){
                                Logger.log("Error downloading the backup file!", Logger.Types.warning);
                        },

                        timeout: 10000
                });     
        }
        else {
                try {
                        backupData = extension.plugin.readFile(backupFilePath);
                } catch (e) {
                        Logger.log("Oops! Can't read the backup file, " + e.toString(), Logger.Types.error);
                        InfoTip.alertI18n("message_cannotReadOptionsBackup");
                        return;
                }
        }

        if (!backupData || backupData.trim().length == 0) {
                InfoTip.alertI18n("message_cannotRestoreOptionsBackup");
                return;
        }

        var options;
        try {
                backupData = $.base64Decode(backupData);
                options = JSON.parse(backupData);
        } catch (e) {
                Logger.log("Oops! Can't restore from this backup file. The backup file is corrupted or invalid, " + e.toString(), Logger.Types.error);
                InfoTip.alertI18n("message_cannotRestoreOptionsBackup");
                return;

        if (!InfoTip.confirmI18n("message_restoreOptionsBackup"))
                return;
