My back is still not (completely) post-processed via FTP to another server. Nearly at the end, I get an error

PHP Fatal error: Call to a member function stat() on a non-object in /var/www/[...]/libraries/joomla/database/driver/mysqli.php on line 202

Joomla is 3.4.7 and Akeeba Backuop is 4.5.1

I already tried the log analyser, without success. The log file can be found here :

Any help? Thank you!

Hello Andrè,

sadly that's a bug introduced in the latest version of Joomla, you can find more info here.
For the records, are you backing up multiple databases or a single one? Did you where in CLI or in the backend?

Thank you for your answer. Yes, I use multiple databases and I started the backup via a cronjob directely as root calling it with "php".

Have a nice day!

Sadly there's nothing we can do, since the error comes from Joomla itself.
The only advice we can provide is to downgrade to Joomla 3.4.6 until a proper fix has been published.
However that's a quite rare bug, it happens when the upload process takes too long and MySQL closes the connection.
You can try to lower the part size for the FTP upload, that should speed up things and prevent the database from closing the connection. It's a long shot, but it's worth trying.

Another thing you can do is to try to change the database type inside Joomla Global Configuration from mysqli to mysql (please note the missing trailing i)

My Joomla Installations are very big (5 to 15 GB). Neither changing from mysqli to mysql nor a lower part size helped in my case, so I downgraded to Joomla 3.4.6 and Akeeba 4.4.3

I will wait for another Jomla release and test again later.

Thank you!
