How can we improve Azure Storage?

SAS behavior for replacing/overwriting blobs

It would be useful to define in the SAS token what to do in case of creating a blob with an existing name. The current behavior replaces/overwrites the existing blob.
Furthermore the default behavior is somehow a security threat, because a hacker having a SAS could replace existing entries.

    Thank you for your feedback. Today, a write (w) permission would be required in the SAS for replacement of existing entries. We have work planned to automatically generate snapshots on overwrites to save existing data in this case. We will provide updates when they become available. For any further questions, or to discuss your specific scenario, send us an email at azurestoragefeedback@microsoft.com.
