You should follow these steps:

1- Create the job:

EXEC dbo.sp_add_job
   @job_name = N'BackupDBTestJob', 
   @enabled = 1, 
   @description = N'Create a complete backup of database TestDB' ; 
GO

2- Add a new step to this job:

EXEC dbo.sp_add_jobstep
    @job_name = N'BackupDBTestJob', 
    @step_name = N'Create the backup', 
    @subsystem = N'TSQL', 
    @command = N'BACKUP DATABASE DBTest TO DISK = ''c:\DBTest.bak'''
GO

3- You can schedule the job:

EXEC dbo.sp_add_schedule
    @schedule_name = N'RunOnceAt23', 
    @freq_type = 4, -- means run daily 
    @freq_interval = 1, -- means run once every 1 day
    @active_start_time = 233000 ; -- means at 23:00:00
GO

4- And attach this newly created schedule to the job

EXEC sp_attach_schedule
   @job_name = N'BackupDBTestJob'
   @schedule_name = N'RunOnceAt23; 
GO

And there is this sample in MSDN that may help.

Answer 2

To back up an entire database:

BACKUP DATABASE { database_name | @database_name_var } 
  TO <backup_device> [ ,...n ] 
  [ <MIRROR TO clause> ] [ next-mirror-to ]
  [ WITH { DIFFERENTIAL | <general_WITH_options> [ ,...n ] } ]
[;]
