  1. Allow encryption of blob storage at a container instead of account level

    Please consider allowing encryption to be applied at a per-container level instead of at the account level. Given a request to store one client's data at a different place, with a different encryption key than another client's data, my only option to comply is to split client data across multiple storage accounts today.

    This is problematic since there's a cap of how many accounts I can have per account (presently at 250), which means that management will grow increasingly more difficult when I have to start spanning subscriptions to access my blob resources.

    Rather, if I were able to encrypt…

      • Server side delete, rename of virtual folder

        Currently if I have millions of documents inside a virtual folder, there is not way to delete them without actually iterating through everything, which is extremely time consuming (weeks to process deletions)

        For example, if you have multiple containers, which in turn have multiple virtual folders with millions of blobs, moving, renaming or deleting the "folder" is impossible without some painfully slow iterating through everything.

        thanks!

            Thank you for your feedback. Blob storage Soft-Delete will allow you to configure automatic snapshotting of blobs and allow you to specify retention periods for those snapshots. Soft-Delete will be configurable directly from the storage account. This feature is currently being worked on. For any further questions, or to discuss your specific scenario, send us an email at azurestoragefeedback@microsoft.com.

          • Azure AD Integration with Storage services

            Do we have a way to tag specific AD users to be allowed to access a blob? if not when can we expect this feature?

            • Improve case sensitivity options by providing optional auto to lowercase

              Recently we attempted to migrate from windows file store to azure blob storage and ran into the problem of case sensitivity with azure blobs. We were migrating html based marketing assets which would be a nightmare to attempt to find all the URL's to assets and to lowercase them. Alternative we would need to write a small site that sits in front to lower case all requests. This would require us to first rename all blobs to ensure they are lowercased. In addition to this we would also need to write something that would upload a file to blob and…

              • Support SSL on blob storage with custom domains

                Currently you can use SSL but you have to user the standard URL. You can create a CNAME to your storage account but most browsers complain that the traffic was rerouted and is possibly an attack. There should be a way to install a domain certificate to your containers.

                Thise idea is a duplicate of https://feedback.azure.com/forums/217298-storage/suggestions/3007732-make-it-possible-to-use-ssl-on-blob-storage-using, which the Azure Team marked as Completed, because you can accomplish this using CDN. But we need the real thing where you can have read/write SAS links to blob using SSL and Custom Domains.

                • Azure Storage - Delete Blob with Snap Shot Fails - Error 409 Conflict

                  We were creating a snapshot each time we updated a blob to preserve the version of the blob. However when we tried to delete the blob we received Error 409 Conflict (error msg did not tell us why). When we changed the delete statement from await blockBlob.DeleteIfExistsAsync() to await blockBlob.DeleteIfExistsAsync(DeleteSnapshotsOption.IncludeSnapshots, null, null, null) the delete worked. Apparently having snapshots associated to a blob causes a delete conflict. Makes sense but can we have a more descriptive error message? Thanks!

                  • Provide a way to encrypt or obfuscate blob names

                    My application stores a lot of files containing user data, where each blob is named after a corresponding primary-key in a relational database.

                    Currently my blob storage container is private and all requests for blobs are proxied through my web application.

                    To reduce server load I would like to expose the blobs directly, however this would mean exposing the raw blob name to end-users, which gives away the unencrypted database primary-key value.

                    I know I can prevent access to blobs using Shared Access Signatures however I don't need that kind of security - I just want to obfuscate blob names…

                    • "Snapshot if exists" function

                      At the present time, running the "Snapshot Blob" operation against a non-existent blob yields an error.

                      It would be very useful to have a "Snapshot if exists" operation (or indeed an option on the present "Snapshot Blob"). So that if a blob does not exist, no error is generated.

                      • Auto defragment append blobs

                        Append blobs are great, however, when a such a blob is generated through a long series of small increments, the read performance of the resulting blob is very poor: from 10x to 20x slower than reading a regular page blob.

                        The performance problem goes away if the app rewrite the append-blob in large 4MB chunks. However, this process is complicated to setup, and collides with any 'always-on' property of the app.

                        As append blobs are append-only, it would be much better if Azure was taking care of defragmenting the append blobs on its own; possible through a dedicated API operation…

                        • 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.

                              • Allow user-based access to Blob Containers (for support employees)

                                For auditing purposes and to prevent data corruption, we want to give our support employees a user-centric, read-only access to Blob Containers in order to be able to investigate possible data corruptions (caused by bugs in systems).

                                This is not possible now because the security architecture of Blob Service does not even know the concept of users or roles.

                                SAS is not secure enough mechanism because it gives access to anyone by just sharing a link + you can't track who's actually using it.

                                • Support "Last Accessed" timestamp in blob metadata

                                  With the new "Cool Storage" feature announced recently, it would be useful if we could tell when our "Hot" blobs were last accessed, so we could push them to Cool storage where appropriate. We could achieve this with a proxy service and SAS signatures, but having this automatically updated in the blob metadata itself would be much simpler and remove the requirement for any compute resource being required for simply accessing a blob.

                                    Preventing others to consume my Azure resources via HTTP_REFERER header validation.
                                    This is a common scenario for blogs, websites etc.

                                    Scott Hanselman has even written a blog post about it: http://www.hanselman.com/blog/BlockingImageHotlinkingLeechingAndEvilSploggersWithIISUrlRewrite.aspx

                                    • move pageblobs already in the cloud to cool storage, you can't!

                                      I was on the phone today with Microsoft Azure. I have 12TB of data in pageblobs that I would like to move to azure cool storage for archiving. Well, the only way to do that is to download them to local HDD and then convert and upload to cool storage. You can not at this time transfer from your azure storage files "in the cloud" over to cool block blobs. Plus, another limitation is that block blobs have a size limit of 195GB due to its internal architecture. I have plenty of pageblobs over 1tb that I would like to…

                                      • more detailed error messages

                                        We've run into an issue where data we tried to store wouldn't fit in the blob file. The error message was (416) The page range specified is invalid.

                                        At first it wasn't clear whether we were trying to start saving beyond the page file or data didn't fit or something else was culprit. Eventually we figured it out.

                                        It would be nice if the error message would provide more details: page size, size we tried to save, location we tried to save within the file, etc. This would've showed us the issue right away. Instead we had to spend a…
