BackupWordPress deletes the database sql backup file

[amsharma9]

Description of issue

I am using BackupWordPress 3.6.4 on Windows 7 64bit using Wamp server. Using WordPress 4.9.8. I installed the plugin and set it up to backup both files and database in only "Manual" mode. When I take a backup it generates the SQL file but deletes it while its still working and taking backup of the files. I end up having only the backup of files.

My wp-config.php contains the following constants:

define( 'HMBKP_PATH', 'R:/' );
define( 'HMBKP_MYSQLDUMP_PATH', 'C:\Wamp\bin\mysql\mysql5.7.14\bin\mysqldump.exe' );

R:/ is a RAM Drive on my laptop. At the end of it I do have the files backup localhost-test-1536049790-complete-2018-09-04-14-52-53 but no database backup. What could be the issue.

Thanks
Amal

The backup file for database which gets created for a few seconds is database-localhost-test-1536049790.sql. It is visible for a very short time and then gets removed from the backup directory.
