|Note many Linux utilities won't gracefully deal with files with spaces in their names. The default filenames for backups are set in backup.class.php - just edit the three lines that look like|
$fname = $this->dbName."-$prefix-".date("Y-m-d H-i-s").".sql";
to replace that space between Y-m-d and H-i-s with something. Another "-" works.
