Copy local file to azure storage

Christian Becker 21

Hi There,

I'm trying to transfer a file from local filesystem inside an Azure Virtual Machine (Debian 12) to Azure Storage. Because azcopy is not available for Debian 12 I'm trying to use az cli directly.

I've tried

az storage blob copy start --account-name mybackupstorage --auth-mode login --destination-blob testfile --destination-container backupcontainer --source-uri file://home/azureuser/testfile

But this results in

The value for one of the HTTP headers is not in the correct format.
RequestId:22f5ada2-601e-0022-4853-fde006000000
Time:2024-09-02T16:18:35.3672485Z
ErrorCode:InvalidHeaderValue
headername:x-ms-copy-source
headervalue:file://home/azureuser/testfile

I've also tried using three slashes but that doesn't work either.

I've also tried az storage azcopy blob upload but that doesn't support Managed Identities.

Could somebody tell me, where I'm thinking the wrong way?

Bests
Chris

Hi @Christian Becker ,

maybe this helps/works? I haven't tested the command:

az storage blob upload --account-name mybackupstorage --container-name backupcontainer --name testfile --file /home/azureuser/testfile --auth-mode login

(If the reply was helpful please don't forget to upvote and/or accept as answer, thank you)

Thank you for your answer. Executing this step leads to a permission error:

You do not have the required permissions needed to perform this operation.

That doesn't make sense as the managed identity has Storage Blob Data Contributor permissions.

Hi Christian Becker,

You are trying to copy a file from your local file system to Azure Storage using the Azure CLI, but you are running into issues with the AZ storage blob copy start command. The problem is with the format of the --source-Uri parameter. The AZ storage blob copy start command is designed to copy blobs between storage accounts or within the same account by using a URL, not a local file.

Firstly, we request to advice that, please go through the below link

https://video2.skills-academy.com/en-us/azure/storage/common/storage-use-azcopy-files

For transfer a file from local filesystem inside an Azure Virtual Machine (Debian 12) to Azure Storage. With using use AZ CLI directly

Set the Subscription (if needed)

If you have multiple Azure subscriptions, you might want to set the default subscription:

Use the Az storage blob upload command to upload a file from your local machine to Azure Blob Storage:

AZ storage blob upload --container-name <your-container-name> --file <path-to-local-file> --name <blob-name> --account-name <your-storage-account-name> --account-key <your-storage-account-key>

Hope the above helps you and feel free to get back to me if you need any assistance.
