I really don’t have enough information so this is a guess, but it looks like a timeout to me. That is, either the MySQL database or PHP has reached a preset execution time limit while trying to create the backup. Unless you have root privileges on the server you will probably have to ask you host for help.
Are you able to make backups using PhpMyAdmin or some other tool provided by your host?

I have root privileges on the server. Backup Database from phpmyadmin works. Also WP Complete Backup for WordPress creates backups.
Well that changes things 0_o
It still sounds like a timeout though… what happens if you put define('WP_DEBUG',true); in your wp-config.php? Do you get any useful information?

I never debugged WP before. In the file /var/www/wordpress/wp-config.php
I added three lines at the end and restarted:
define(‘WP_DEBUG’, true); // Turn debugging ON
define(‘WP_DEBUG_DISPLAY’, false); // Turn forced display OFF
define(‘WP_DEBUG_LOG’, true); // Turn logging to wp-content/debug.log ON
Than I tried to backup database in Backup Manager. But the file wp-content/debug.log is not created?
Just use the one define('WP_DEBUG', true); // Turn debugging ON line. It will make a bit of a mess but you don’t need to leave it turned on very long– just long enough to see if that plugin generates errors.
If you also add define('WP_DEBUG_LOG', true);. you’ll also get a nice debug.log file in your wp-contents folder.

Yeah, he said that wasn’t working though. The file isn’t being created, which may be a symptom of the same problem.
@svenk, where does Backup Manager save its backup file?
What are the permissions on wp-content? Has the ownership of the folder been checked?

That is what I was thinking, spurred by your earlier comment. If Backup Manager is saving to wp-content and the permissions are wrong, then there is the problem.
First of all, sorry for the late reply.
I’m aware of this issue and there are some other people who encountered the same problem as well. This will hopefully be fixed in the next version as all those processes will be completely overhauled.
Thanks for using WordPress Move and sharing your experience.
Also, thanks s_ha_dum and esmi for assistance 🙂

Nothing happens when I put define( ‘WP_DEBUG’, true );
in the file /var/www/wordpress/wp-config.php
Why debugging is not working?
DBBackup* files with the size 0 are stored in:
/var/www/wordpress/wp-content/plugins/wordpress-move/backup
I compared permissions with a site where WP-move works. There are the same. Ownership is by www-data user and group. The difference is, on not-working site I’m using multilingual plugin WPML and some others.
I’m having the exact same problem. I used this plugin last week on another site I’m running with no issues. I get the same zero byte sized backup file after running a backup using Backup Manager. I can create backups successfully using BackWPup.
Odd, I tried it today and it worked creating the backup.
