Azcopy: Copying files to an Azure Fileshare using Azcopy 10 - azure

Question

I'm trying to copy files to and from an Azure Fileshare using AZCopy v10. I have had this successfully working using v8.1 but I keep getting errors using v10.
From the command line I'm using this to copy a file from the local drive to the fileshare;
c:\Temp\azcopy.exe copy "c:\temp\sample.txt" "https://myfiles.file.core.windows.net/dbfiles/sample.txt?SASKeyText"
This generates the error message;
failed to perform copy command due to error: cannot transfer individual files/folders to the root of a service. Add a container or directory to the destination URL
I have tried adding a directory to the fileshare and adding that to the command string but I get the same error.
If I reverse the copy from the fileshare to the local drive I get the error;
failed to perform copy command due to error: account copies are an inherently recursive operation, and thus --recursive is required
I have followed the guide at https://learn.microsoft.com/en-us/azure/storage/common/storage-use-azcopy-files but haven't been able to see what's wrong.
Thanks in advance for any help.

Answer 1

The error here was with the SAS token and not the form of the command.
I suppose this should be marked up amongst examples of unhelpful error messages.
Thanks to everyone who took the time to have a look.

I had this same issue when trying to do a copy from my local machine to Azure Blob storage.
This was the command I was running:
azcopy copy --from-to=LocalBlob "C:\AzureStorageTest\my-app\*" "https://myapptest.blob.core.windows.net/%24web" --recursive
But I got the error below:
failed to perform copy command due to error: cannot transfer individual files/folders to the root of a service. Add a container or directory to the destination URL
Here's how I solved it:
I was missing the ?[SAS] argument at the end of the Blob storage location. So instead of this:
azcopy copy --from-to=LocalBlob "C:\AzureStorageTest\my-app\*" "https://myapptest.blob.core.windows.net/%24web" --recursive
I had this:
azcopy copy --from-to=LocalBlob "C:\AzureStorageTest\my-app\*" "https://myapptest.blob.core.windows.net/%24web?[SAS]" --recursive
Note:
The format is azcopy copy "/path/to/dir" "https://[account].blob.core.windows.net/[container]/[path/to/directory]?[SAS]" --recursive. You only need to modify the "/path/to/dir", [account] and [container]/[path/to/directory]. Every other thing remains the way they are.
Specify the source-destination routing using the --from-to=LocalBlob (if you're copying from local to blob storage) argument to be explicit about the copy operation.
My actual Blob storage location is https://myapptest.blob.core.windows.net/$24web but I used https://myapptest.blob.core.windows.net/%24web, since $ will throw some error when used, so %24 was used.
That's all.
I hope this helps

Here is a sample azcopy script which worked for me
az storage azcopy blob upload
-c'https://$AZURE_STORAGE_ACCOUNT_NAME.blob.core.windows.net/\\\$web' \
--account-name $AZURE_STORAGE_ACCOUNT_NAME \
-s "build/*" \
--account-key $AZURE_STORAGE_ACCOUNT_ACCESS_KEY \
--recursive

If you get this error while trying to copy to $web container:
"failed to perform copy command due to error: cannot transfer individual files/folders to the root of a service. Add a container or directory to the destination URL"
Per a solution listed here, we need to add an escape character (\) before $web. Following command (to copy all files and subfolders to web container) worked for me:
azcopy copy "<local_folder>/*" "https://******.blob.core.windows.net/\$web/?<SAS token>" --recursive
Without the escape character, the following command fails with the above error.
azcopy copy "<local_folder>/*" "https://******.blob.core.windows.net/$web/?<SAS token>" --recursive
