The failure is from storage server, so the size limitation is on server instead of Powershell. You might can raise a help ticket on Azurite portal to get help to server team: https://learn.microsoft.com/en-us/azure/azure-portal/supportability/how-to-create-azure-support-request#go-to-help--support-from-the-global-header. (Besides the above request trace, you might can also share the blob type.)
You can also try following workaround:
- For transfer of big data , we would recommend using AzCopy, it will be more stable and fast in transfer big data, you can call AzCopy command in your PSH script: https://learn.microsoft.com/en-us/azure/storage/common/storage-use-azcopy-v10
- If you must use Powershell cmdlet, you can try "Copy-AzStorageBlob" cmdlet, this is Sync copy cmdlet and will copy data chunk by chunk. It will be very slow for 8TB blob. (Start-AzStorageBlobCopy is async copy, it will just send copy request, but won't wait for copy finish).

Description
When I try to copy a snapshot with a size of 8192GiB using Start-AzStorageBlobCopy, it fails with the error below. For smaller snapshots, it works. Is this an intended limitation of Start-AzStorageBlobCopy? I did not find anything in the documentation.
