Yes, I’ve tried.
I’m running WP in a subdirectory, and use WP 3.5.x.

It seems there is a bug when downloading the backup files.

This is the content of downloaded files

Warning: filesize(): stat failed for /path/to/public_html/content/backup-db/1372805295_-_novrian.info_.sql in /path/to/public_html/content/plugins/wp-dbmanager/wp-dbmanager.php on line 383
