We have a problem with making a backup without a progress bar being shown. The Waiting time (TTFB) is very high, nearly as much as the time of the backup. When the backup is nearly finished a progressbar is shown or the message that the backup is ready. In the meantime the webpage remains unchanged (I can see the request is in progress).
This behavior is not the case in every backup test and on different networks. Could it be a problem with our firewall that blocks the response of this specific backup process?

It's difficult to say what's the bottleneck here. Did you also look at the performance and network tab in Firebug?
Did you also check the logfiles on the server to see if some task is taking so much time?
You can also use the developersmode in Moodle to get more debug information (only use it in a test environment).

Did you use Firebug to test on the client? We had also long login times and the problem was the service.php call that wasn't able to connect and timed out every 30 seconds. The solution was configuring the proxy server in Moodle.

Ken, thanks for the tip. I knew Moosh already, it wasn't enough for me so I wrote a script that looks from the metadata in the database at the files on the filesystem. Moosh looks for files without metadata (orphans).

Howard, we're still investigating why the files are missing after the migration. That's why I made the bash script.
