JoomlaCloner has reached version V1.7, beside some small bug fixes, we have added a new improvement to the backup generator process called "Manual Backup"!
This new feature allows users which have sites limited by a php time execution(usually 500 error, blank page, or save index.php message when generating a backup), to create incremental backups, so the total backup generator time is splited into smaller pieces!
All you have to do is to upgrade the component, and activate the "Manual Backup" in your Configuration area!
For more info about this process please review our Documentation
