Hardware and performance

Hi

> does it mean that syncing the remote and local server is not possible and updates made in local server will not get reflected in the remote server.

The short answer is: Yes.

You can find the explanation in the answer I gave in the "Installaton problems" forum

This idea is often discussed in the "Hardware and Performance" forum http://moodle.org/mod/forum/view.php?id=596 for example http://moodle.org/mod/forum/discuss.php?d=173408.

You'll find more discussions searching that forum for "replication" and "mirror". Make use of the "'Using Moodle' advanced search facility" mentioned in the introduction to that forum.
