You need to request your service provider to raise the upload and post limits to be large enough to cover your course.  Otherwise, you need to backup your course into multiple smaller files and upload that way.  e.g. Just back up one week/topic at a time.

Presumably a database inconsistency In mdl_book?) due to the upgrade route.

Any suggestions?

Now solved. Actually, the debug was very informative, but in case it helps anyone else.

A quick comparison of the mdl_book table of each instance using phpMyAdmin showed that the intro field (column) was missing from the upgraded version.

As we only had one or two earlier uses of the book module (and we have an archive 1.9 site with these on), I simply deleted it from the Moodle Manage activities Admin interface, then let it reinstall from the Notifications link to give the new mdl_book table with an intro field.

Now courses, from the other  2.3.1 instance, restore fine.

Hi Niles, I have not tried it yet because I host my moodle on my own server. But just sharing my thoughts.

How about striping out the big files first before creating a backup and then restore it. Without big files your course should be less than 10MB. If it's working, then create a repository to which you can ftp you large movie/files/presentation, and then re-link it again afterwards.

Just a thought smile

Hi Niles

Sorry, I don't have a satisfactory answer, not for Moodle 2.x.

The other day I was faced with the same problem. I had to restore a big course backup in my Moodle server. The backup file was in a (different) ftp server. But downloading it to my local machine and uploading to back in to the Moodle server was not an option, I am on holidays in a remote place and my whacky mobile internet connection wouldn't have allowed it, even if I raised the file upload limit. Luckily it was Moodle 1.9. I logged into the Moodle machine over SSH and did the following:
$ cd /path/to/moodledata/1
$ wget ftp://the.host.name/path/to/backup-something.zip

Then logged into Moodle as admin restored the backup into a new course.

How does one do that in Moodle 2.x? Should this work http://docs.moodle.org/21/en/File_system_repository#Creating_folders_for_your_file_system_repositories ?

When I click the "More information about this error" link, I am taken to a help page on moodle.org but it page is blank.

Is this type of restore possible?

Emma,

We do not have a service provider. we are running Moodle 2.2.3 on our own server. I have a backup for a computer course that is 1.14 GB The MBZ file (backup-moodle2-course-ist2300.mc-fa0111-20120521-2357) is the only file I have. The old course has been deleted and when I try to restore it from this MBZ file I am able to upload as the first step of the restore process. When I push the RESTORE button it sits and churns for hours. We let it run assuming that it was so large.

I have raised the limit to 2 GB and set the limit as mentioned in this post thread to 0 also. I still have no success.

Is it possible something is corrupted and if so is there a way to extract information. The course was taken down before a student was able to complete requirements to change an incomplete grade.

Do I need to repost this to everyone generally in this forum? Any suggestions?

I appreciate any help or sympathy.

Have you spoken to HostGator about this yet?

As I understand it, and please let me know if this is not correct, shared servers allocate a space allottment to a user, you cannot go over that allottment, you try and you get errors - lots of them. Could this be a cause? Have you checked your server logs? What do they say? 

One way around these kinds of issues is that when you upgrade your Moodle, you do it over the top of your existing Moodle, that is, you delete all your Moodle files, not the database, not the moodledata folder and definitely NOT the config.php file, just the moodle php files. You then unzip the newer version over the top of the now blank Moodle. Log in as per normal and it should begin the upgrade on its own. I have done this from a 1.9.13 to a 2.2.3 and it worked, but it did not have that many users, 112 right now, and less than 60 courses. Worked well actually, much to my surprise, but that is not a shared server...

Just a quick clarification about http://www.conversionthingy.net/ : it doesn't convert user data, only resources. Basically, it's only intended to convert old 1.9 zip backup file to 2.0 mbz backup files. But from 2.1 this process is completely managed by moodle itself. So, altough the programm works well in the conversion process, you shouldn't need this program to restore a backup file from 1.9 to 2.1 upwards.

This error occurs on our automated backups.

We are using MS-SQL 2008 R2. We are using the sa (SQL admin) account to connect to moodle so should have full priviliege to create/delete tables.

In the Course backup log it just says Error next to the course.  There is no link on the course name to go to a more detailed log which I have read should happen.

Any ideas appreciated.

I am getting the same error when trying to backup on about half of our courses.  I do not know if they are all (there are over 1,000) upgraded 1.9 courses now running on 2.2.4+ but the first couple I have checked are.

The backup works successfully if I do not include users.

Error 500 when restoring course

volgens Nick Oliver.  

Hi,


I am in the process of moving from Moodle 1.9 to Moodle 2.3. As part of this I am backing up and restoring old courses. Many of my courses have copied across fine onto the new system. I have 60+ courses that are failing to restore. When I try and restore the courses they come up with the 500 error on the browser. 

 

When I attempt to restore the backup I get to Step 2 and choose to delete the content of the course. When I hit continue the 500 error comes up (this is the same in all courses I tried,) but with the other courses I was able to press F5 to continue. This doesnt work on these 60 courses though so I am unable to continue.

 

My environment is: Server 2008R2, IIS 7.0 and MS SQL 9.0, PHP 5.3.13 and all are fine for the current environment we are running.

 

If anyone can provide any advice it would be much appreciated! I have been wracking my brains all week to try and sort this, I have tried deleting some stuff out of the backups, using small backups, large backups, remaking the backups, system made backups and nothing works! I would rather not have to recreate all 60 courses from the ground up!

 

Thanks. Nick.

Morning! 

 

Now I think this is actually something I may be able to help with, this is all down to the time allowed to upload the file by PHP. Now I think I am right in thinking here that if you follow these steps you should be able to change it and it "should" work. 

 

1. Go in to your Moodle folder (or the folder where your Moodle code is,)

2. Go to your PHP folder and find php.ini

3. If you look for line 126 you should have a max execution limit on there of the 30 seconds, if it is a big file I would bung a few 000s on the end of this to allow it upload this file but remember to change it back afterwards.

ALSO PLEASE ENSURE YOU BACKUP OR MAKE A COPY OF PHP.INI before you make ANY changes.

 

Hope this helps.

 

Thanks. Nick.
