You may receive a warning from your webhost about your site exceeding the Allowed CPU seconds.

This may happen very rarely during your first backup and it would depend upon the site size and the number of files on your website.

Not to worry, since the first backup takes into account all of your files and processes them to be uploaded on your cloud storage, the number of calls will be higher.

The subsequent backups will happen real quick and will in no way exceed the daily allowed CPU seconds.

Note: On earlier versions, there would be a progress bar that would constantly auto-refresh adding excess load to the existing load. We've changed it to refresh manually thus reducing the CPU usage.
