Backup Error processing archive file

Automatic backup task has an error. The server task gives a delay.

Executing automated_backup_task in CLI gives the error:

  • Backing up XXXX.

    ... used 18 dbqueries

    ... used 21.788386106491 seconds

    Scheduled task failed: Automatische backups (core\task\automated_backup_task),Fout bij het verwerken van het archiefbestand (note: Error processing archive file)

The manual backup runs ok. Activating debugging there gives the result:

  • setting controller status to 700
  • saving controller to db
  • calculating controller checksum 41e7d1628d542dcc0905e50eb1628dbe
  • loading controller from db
  • setting controller status to 800
  • setting controller status to 1000
  • saving controller to db

I'm using Moodle 3.0.3+ (Build: 20160506) 

What could be wrong? What's blocking the automatic backup

Hard to say ... so more questions ...

When the automated backup script fails, Is there a directory in /moodledata/temp/backup/ with a long name ... something like '02a5c174a5e99ff94ee40113ae54a9929c638e4d'.  If so, there should also be a matching .log file that might give a hint at what stage the course backup failed.

If it reached 900 (finished is 1000) could be there is a valid good backup with an .mbz file extension in (as per example) 02a5c174a5e99ff94ee40113ae54a9929c638e4d.   The very last step in the backup process is to *copy* the backup to a destination .... if set to defaults, that is back into the sea of files in moodledata/filedir/   Depending upon operating system and permssions/ownerships of moodledata that could be the hickup ... can't copy the file ... notice that's copy ... not move.

Then there is always a chance that another automated task to clean up is actually romping on the automated backup ... ie, clean up happens while Moodle trying to complete an automated backup.
