    This is what I did for backup and restore of my localDb

    public void BackupDatabase(string filePath)
    {
        using (TVend2014Entities dbEntities = new TVend2014Entities(BaseData.ConnectionString))
        {
            string backupQuery = @"BACKUP DATABASE ""{0}"" TO DISK = N'{1}'";
            backupQuery = string.Format(backupQuery, "full databsase file path like C:\tempDb.mdf", filePath);
            dbEntities.Database.SqlQuery(backupQuery).ToList().FirstOrDefault();
        }
    }

    public void RestoreDatabase(string filePath)
    {
        using (TVend2014Entities dbEntities = new TVend2014Entities(BaseData.ConnectionString))
        {
            string restoreQuery = @"USE [Master]; 
                                                ALTER DATABASE ""{0}"" SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
                                                RESTORE DATABASE ""{0}"" FROM DISK='{1}' WITH REPLACE;
                                                ALTER DATABASE ""{0}"" SET MULTI_USER;";
            restoreQuery = string.Format(restoreQuery, "full db file path", filePath);
            var list = dbEntities.Database.SqlQuery(restoreQuery).ToList();
            var resut = list.FirstOrDefault();
        }
    }



    Hope this is what you want.
