Hello TLIT,
Thanks for reaching out, to address the timeout issue with the dynamic plan in Azure Functions while syncing blobs using AZCopy every 3 hours, switching to the Premium Plan is the recommended solution. The Premium Plan offers a longer execution timeout, making it ideal for long-running tasks like AZCopy. While the estimated cost is around $150 per month, the actual cost can vary depending on execution time, memory usage, and frequency. Using the Azure Pricing Calculator can help you estimate the precise cost based on your specific usage. By moving to the Premium Plan, you can ensure smooth and uninterrupted sync operations without being limited by the 5-minute timeout of the dynamic plan.
