[Snapshot Pro] Snapshot time issue

I get a warning message that my site is not set up with a long enough time to create back ups with Snapshot. My site is set to 30 seconds. The assistance for fixing this issue is beyond my skills.

Can you help? The error is listed below.

Max Execution Time WARNING max_execution_time is set to 30 which is too low. A minimum execution time of 150 seconds is recommended to give the migration process the best chance of succeeding. If you use a managed host, contact them directly to have it updated.
