If the site’s size is large, it needs many consecutive calls to back up the entire DB and files.
We have the default call limit set to 1500. When the backup fails with the above error, the admin panel will automatically increase the limit to 3000.
But if you still encounter the same error, you can increase the limit further by adding the below line to your IWP config.php file.
define('MULTICALL_LIMIT_COUNT', 5000);
