Archive Size: (detection limit is set at )
PHP max_execution_time: (zero means not limit)
PHP set_time_limit: SuccessFailed

The PHP max_execution_time setting is used to determine how long a PHP process is allowed to run. If the setting is too small and the archive file size is too large then PHP may not have enough time to finish running before the process is killed causing a timeout.

Duplicator attempts to turn off the timeout by using the set_time_limit setting. If this notice shows as a warning then it is still safe to continue with the install. However, if a timeout occurs then you will need to consider working with the max_execution_time setting or extracting the archive file using the 'Manual Archive Extraction' method.   [Additional FAQ Help]
