Impossible to restore big courses (greater than 50 Mo)

[martignoni]

When attempting the restoration of big courses, error errorcopyingbackupfile occurs.

Related to the size of temp directory, limited to 64MB (see https://github.com/martignoni/make-moodlebox/blob/master/make_moodlebox.sh#L478).

For reference, here's a possible solution to the bug. Needs a separate partition :-(

Separate partition is not an option.

Still looking for another solution. As a (partial) workaround, one could increase the temp directory size in fstab.

After above fixes, it should be possible to restore course up to 120 MB.

Restoring bigger courses would need to disable RAM temp partition, with an overall bad performance of the MoodleBox.

I'd like to provide a durable fix for this.

The following solution (tested) seems to work:

• When creating the MoodleBox image, make a new /var/www/moodledata/backup directory (mkdir -p /var/www/moodledata/backup)
• Fix owner (chown -R www-data:www-data /var/www/moodledata/backup)
• Fix permissions (chmod -R ug+ws,o-w /var/www/moodledata/backup).
• Soft link it to /var/www/moodledata/temp/backup/ (ln -s /var/www/moodledata/backup /var/www/moodledata/temp/backup)
• Add a crontab @reboot redoing the link at boot time, since the temp folder lives in RAM and everything inside is deleted at shutdown.

If this solution is retained, we could lower the size of the RAM partition for the temp dir.
