Moodle 3.3.5 and problems doing backup

Hi,

i was using Moodle 3.3.4 with no problem. Since i've installed Moodle 3.3.5, i've got problems doing backups for some courses (a lot) ; other courses backup well.

Automatic backups fails, manual backup (and importation) are also concerned.

When doing a backup (with everything), when trying to go to the step 3 (confirmation), i got an error message : error/setting_invalid_filename

For the moment, i've not found where the problem comes from.

Do other people have the same problem? Ideas about it? A solution?

Don't speak French ... wish I did sometimes ... haven't experienced the same problem myself so this is a 'sluething guess' just looking at what it's showing in debug ...

setting_invalid_filename and it's the name of the backup file.

sauvegarde-moodle2-course-83-m2_dmse_-_ue3-théorie_des_organisations_-p4_foad-20180321-1633.mbz

The backup settings have options for what to name the backup file ... .mbz is the extension.  so in those one could opt to use course shortname, etc..

I see a 'é' in the backup file name which should be ok, but the other items that involve a '-'?

'_-_' and '_-p4' ...

what if you changed the shortname/longname of the course removing the "spacedashspace' or 'spacedash' in front of p4 - in other words ... remove the dashes and use only one space.

Hi Ken,

and thanks for your answer and suggestion.

For what i've seen, some other courses containing same signs work well.

But i've discovered that all courses in error (in automatic backup) have a shortname over a certain value, and thus a backup filename over a certain value, which seems to break the backup processus (now).

I'll have to do more tests to confirm the value.

And then, the need to understand what changes between Moodle 3.3.4 and 3.3.5 which make backups impossible.

I don't know if this is relevant but I did see a tracker issue about backup file names over 255 characters - is this anything to do with your problem? https://tracker.moodle.org/browse/MDL-33886

(Whatever it is, it is fixed for 3.34 mixed so maybe not...)

Re: Moodle 3.3.5 - impossible to make backup when course shortname is "long"

Hi Mary,

Thanks for your help, but i'm not concerned by this issue.

I've rather created MDL-61723 for this new problem.
