Backup and restore

Hi,

it can happen when the course is too big. You can try to make the backup of this course in command line. The script is in the admin/cli directory.
If it's also possible activate the debug to see the exact error.
And somtime even if the UI display a timeout the backup is restored.
You can also activate the backup/restore asynchronus it maybe also avoid the error.

Hope it's help.

Dominique.
