Automated backups unfinished

Hi everyone, recently I'm having a problem with a automated backups in Moodle. When I try to backup manually all courses, cerminal shows this error,

Server Time: Mon, 17 Aug 2020 11:09:46 +0200

Execute adhoc task: core\task\course_backup_task

... started 11:09:46. Current memory use 35.2MB.

Processing automated backup for course: Física.1BA(BO)

Automated backup for course: XXXXX encounters an error.

Exception: No se puede encontrar registro de datos en la tabla backup_courses de la base de datos.

Debug: SELECT * FROM {backup_courses} WHERE courseid = ? AND laststatus = ?

[array (

  0 => '165',

  1 => 6,

)]

Has anyone have the same problem or know the solution?

Thanks in advance
