The upload speed mentioned for the site is 20Mbps(its Bits not Bytes). Divide that by 8 to get the bytes which will translate to 2.5MBps. Now per min will be 2.5MB * 60 = 150MB. Per Hour will be 150MB * 60 = 9000MB (9GB). Per Day will 9GB*24 = 216GB. Over the course of 7 days it will be 216GB*7 = 1512 GB (1.5TB). I dont think it 30TB can be sent within 7 days

Azure Import/Export service is used to securely import large amounts of data to Azure Blob storage and Azure Files by shipping disk drives to an Azure datacenter. # https://docs.microsoft.com/en-us/azure/import-export/storage-import-export-service

ignore my comment. Azure import/export service is used to send data by shipping the local disk to Azure data center so it is possible. so correct answer is 'YES'

You are limited to your 20Mbps upload speed. Therefore, it would take more than seven days if you transfer data using any tools. So, other available option is to copy data to disk and send it to Microsoft. Answer is Yes

30 terabyte = 31457280 megabyte uploading 20 megabyte/seg you require 31457280/20 = 1572864 segs convert in days = 1572864/(3600*24) = 18.2 days. Then is no possible upload in time.

Forget the previous comment. The size is not a matter because the data is sent to Azure by a carrier (FedEx/DHL)

Not so sure about this, the solution makes sense given the network connection speed, but Import/Export doesn't guarantee completing the job within 7 days. https://docs.microsoft.com/en-gb/azure/import-export/storage-import-export-view-drive-status#time-to-process-job

The question just asked: All backup data must be sent within seven days, keyword is "sent" the time to complete the import process is irrelevant

I also doubt A: Import/Export service doesn't have an SLA, but the service strives to complete the copy in 7 to 10 days after the disks are received. We all know "Microsoft Minutes :-)".
