Backup and restore

Hello,

I have had a repeated, and still not solved, problem with the nigthly scheduled backup. There are a couple of courses that cannot be backuped although I can back them up manually.

It is not a problem of file size, neither a problem of execution time (at least I think so).

I have read on this forum about similar problems, but I have not found a definitive solution.

What I was now trying to do is to use a client php parser (CLI PHP), instead of "lynx", to run the "cron.php" script, as proposed in the Moodle documentation and in some topics of this forum.

I have installed the "php4-cli" package from Debian and, when I try and use it, it does not work. When using it manually I always obtain the same error:

Fatal error: Call to undefined function: init_performance_info() in /var/www/moodle/lib/setup.php on line 93

Any suggestion?

Thanks in advance.
