We are excited to announce the public preview of Entra ID-based access for Azure Blob Storage SFTP. This new capability enables you to use Microsoft Entra ID (formerly Azure Active Directory) identities (including guest users via Entra External Identities) to securely connect to Azure Blob Storage via SFTP without needing local users. This feature eliminates the operational overhead of managing local SFTP users and passwords by introducing enterprise-grade identity management powered by Microsoft Entra ID. For IT administrators and security teams, this means no more creating, tracking, rotating, or decommissioning local SFTP credentials. For developers and architects, it means seamless integration with your existing identity infrastructure. For business users, it means faster, more secure access to the data they need, all while maintaining compliance with enterprise security policies. Azure Blob Storage SFTP Azure Blob Storage SFTP natively enables secure file access and management without third-party solutions. This simplifies operations for customers and removes the need for complex, custom SFTP solutions. Until this Public Preview, Azure Blob Storage SFTP utilized a form of identity management called local users as the only authorization mechanism. Local users must use either a password or a Secure Shell (SSH) private key credential for authentication. Learn more about local users here. The Challenge: SFTP Local User Management Organizations currently face challenges when managing SFTP access at scale with Azure Storage SFTP Local Users. Local User based SFTP access require IT teams to: Manually create and provision local user accounts for each SFTP user Generate, distribute, and securely store SSH keys or passwords Implement custom workflows for lifecycle management Manage offboarding processes to ensure departed users lose access immediately Audit and track access across disconnected identity silos Handle external partner and vendor access through ad-hoc, often insecure methods The Solution: Enterprise Identity Meets Secure File Transfer With Entra ID-based access for Azure Blob Storage SFTP, you can now leverage your organization's centralized identity platform to authenticate and authorize SFTP users. This integration brings the full power of Microsoft Entra ID to your file transfer workflows, delivering the following benefits: 1. Eliminate Local User Management Simplify SFTP management by assigning access with Entra ID—no separate SFTP accounts needed. No local credential generation or distribution—users authenticate with their existing corporate credentials No orphaned accounts when users change roles or leave the organization Reduced attack surface by eliminating static, long-lived local credentials Centralized user lifecycle management through your existing identity platform 2. Enterprise-Grade Identity and Security Leverage the full security capabilities of Microsoft Entra ID for your SFTP infrastructure: Multi-Factor Authentication (MFA): Require additional verification factors beyond passwords, significantly reducing the risk of account compromise Conditional Access: Define policies that grant or block access based on user location, device compliance, sign-in risk, and other conditions Identity Protection: Benefit from Microsoft threat intelligence and risk detection to identify and respond to compromised accounts Privileged Identity Management (PIM): Provide just-in-time elevated access for administrative operations 3. Native Azure RBAC, ABAC, and ACL Integration Your SFTP access control seamlessly integrates with Azure comprehensive authorization framework: Role-Based Access Control (RBAC): Assign built-in or custom roles at the storage account, container, or even blob level Attribute-Based Access Control (ABAC): Create sophisticated access policies based on resource tags, user attributes, and environmental conditions Access Control Lists (ACLs): Apply fine-grained permissions at the directory and file level for hierarchical namespace-enabled accounts Unified Permission Model: SFTP access respects the same permissions as REST API, Azure CLI, and other access methods—no separate permission system to manage 4. Faster SFTP Onboarding and Time-to-Value Onboard new SFTP users or partners in minutes instead of hours or days, saving significant time and boosting business agility. 5. Secure External Collaboration with Entra External Identities Seamlessly enable secure external SFTP access by allowing partners to authenticate with their own credentials using Entra External Identities (Azure AD B2B). External users authenticate with credentials they already manage Full audit trail of external user activity Ability to apply Conditional Access policies to external users Automatic access revocation when B2B relationships end Real World Scenarios Financial Services: A bank receives daily transaction files from merchants via SFTP. Merchants authenticate with their own Entra ID credentials (B2B collaboration), MFA is enforced, and access is restricted to assigned directories. Access is instantly revoked when a merchant is removed from the B2B directory. Healthcare: A hospital exchanges patient data with insurers and labs. Entra ID authentication ensures only authorized staff access sensitive PII, with full audit logs for HIPAA compliance. Conditional Access restricts connections to approved locations and devices. Media & Entertainment: A production company enables freelance editors and agencies to transfer large media files. Entra External Identities provide time-limited access and automatic revocation when projects end—no need for local SFTP accounts. Manufacturing: A manufacturer receives CAD files and orders from suppliers using SFTP. With Entra ID, suppliers use unified credentials and access policies across all systems, streamlining supply chain management. How It Works Entra ID simplifies SFTP access to Azure Blob Storage by authenticating users with their corporate credentials. After authentication, users receive a short-lived Open SSH certificate to connect. The service verifies certificate validity and user permissions, enabling secure file operations and automatic access revocation in line with current identity policies. Learn more here.

We are excited to introduce the public preview of smart tier for Azure Blob and Azure Data Lake Storage. Smart tier is a fully managed, automated data tiering solution that takes the guesswork and manual effort out of optimizing your storage costs. Smart tier continuously analyzes your data’s access patterns and automatically moves objects between the hot, cool, and cold tiers. Smart tier will keep regularly accessed objects on the hot capacity tier to optimize transaction costs and moves inactive objects after 30 days to the cool tier capacity tier and after an additional 60 days of inactivity to the cold capacity tier. If you access an object in cool or cold tiers again, it’s instantly promoted back to the hot tier, restarting the cycle. This ensures your data is always in the most cost-effective tier with zero manual intervention, making it the ideal online tier for datasets with mixed or unknown access patterns. Getting started Using smart tier is quick and easy: Enabling smart tier is simple: Just select smart tier as the default access tier through the storage account configuration for any storage account with zonal redundancy. Smart tier is available in all zonal public cloud regions, supporting both flat and hierarchical namespaces. Billing is straightforward: You will pay the regular hot, cool, and cold capacity rates, with no extra charges for tier transitions, early deletion, or data retrieval. Even moving existing objects into smart tier does not incur tier change fees. There’s just a small monitoring fee for the orchestration. Smart tier is configured at the account level. It can be configured via API or the Azure portal as the default access tier setting for new and existing storage accounts. Existing objects following the default access tier setting from the account will be moved to smart tier automatically. Objects that are explicitly tiered, i.e. to the hot tier, will remain in the same account and will not be moved to other capacity tiers. Smart tier will always keep small objects that are below 128 KiB in size in the hot capacity tier for efficiency and those objects will not incur a monitoring charge. If objects below 128 KiB increase in size, the smart tiering patterns apply for those objects as well. The automatic down tiering of inactive data, paired with the billing model simplifications of Smart tier can lead to large cost savings over time. In the metrics view of the storage account you can see the distribution across the capacity tiers for smart tiered objects by both object count and capacity. This account shows smart tier in action, moving inactive objects to the cool and cold capacity tier, thereby drastically reducing the capacity charges without any manual intervention. "2 years ago, Qumulo partnered with Microsoft to deliver the first truly elastic, unlimited capacity, fully managed file system, Azure Native Qumulo, which was built on Azure Blob," said Brandon Whitelaw SVP of Product at Qumulo. "Qumulo shared feedback with Microsoft on our ideal solution for data tiering and Microsoft clearly delivered, meeting all expectations. With today's smart tier announcement, Qumulo will immediately enhance our offerings with these new capabilities, delivering greater functionality and control over data lifecycle management. We are thrilled with the feature set Azure is delivering at launch” Note that smart tier is not supported with append and page blobs. Smart tier is the ideal tier to choose when you are looking to store your data on standard online tiers but are not fully aware of the data access patterns or do not want to manage data transitions across online tiers. Objects managed by smart tier are not subject to lifecycle management policies, ensuring that automated tiering decisions are based solely on access patterns. Smart tier for block blobs is now available in public preview for both Azure Blob Storage and Azure Data Lake Storage for storage accounts with zonal redundancies, including ZRS, GZRS and RA-GZRS. Unlock cost savings by adding smart tier to your blob storage accounts in one easy step: https://aka.ms/BlobSmarttier. Please reach out to us for any feedback or questions, we would love to hear from you: smartblob@microsoft.com
Manage/restore metadata when blob is updated
I'm using an Azure Storage container of block blobs as a data source for an Azure AI Search Index, and I'm using Blob metadata key value pairs for some custom data. But metadata gets wiped when a blob is updated. How are folks managing that? For reference, I've got a CosmosDB set up also for now with a cross-reference I can restore from, but it's manual. I considered using Cosmos as my data source instead, but I also need a place to store/serve media files from related to these records.
Priority Replication for Geo Redundant Storage and Object Replication is Generally Available
We are excited to announce the General Availability of priority replication for Geo Redundant Storage (GRS) and Object Replication (OR). Priority replication enhances the replication process of GRS/GZRS and OR, ensuring guaranteed 15 minute synchronization between regions and improved replication times. Enabling priority replication will also provide an official Service Level Agreement (SLA) for all user workloads that meet the SLA criteria. What is Geo Priority Replication? Azure Storage has offered users the choice of geo-redundant (GRS) or geo-zone-redundant (GZRS) replication for their storage accounts for several years. As displayed in the diagram below, with GRS/GZRS, data in the storage account is asynchronously replicated from the primary region to the secondary region: Since the data is asynchronously replicated, in the event there is a disaster in the primary region, and an unplanned failover is initiated, there is a possibility of some data loss. The Last Sync Time (LST) property of a GRS/GZRS account is currently used to provide users with the recovery point objective (RPO) of their account. The LST of the account indicates the most recent time that data from the primary region is guaranteed to have been written to the secondary region. All data and metadata written prior to the LST is guaranteed to be available on the secondary. However, any data or metadata written after the LST may not have been replicated to the secondary and could be lost in the event of a disaster impacting the primary region or an unplanned failover. Azure Blob Storage is now introducing Geo priority replication which will provide an SLA guarantee for the LST/RPO of Block Blob data in GRS/GZRS accounts. Geo priority replication enhances the replication process of GRS/GZRS storage accounts allowing for accelerated replication between the primary and secondary regions. The SLA guarantees the Last Sync Time of Block Blob data will be 15 minutes or less 99.0% of the billing month. With this guaranteed sync time, users can feel more confident about their data’s durability and availability, especially if there is an unexpected outage and failover in the primary region. Please refer to the official SLA Terms for a comprehensive list of eligibility requirements. Geo Priority Replication supports the following SKUs: GRS, RA-GRS, GZRS and RA-GZRS for Block Blob data. What is Object Replication Priority Replication? Without priority replication, object replication asynchronously copies all operations from a source storage account to one or more destination accounts, but completion time is not guaranteed. Object replication priority replication will allow users to obtain prioritized replication from the source storage account to the destination storage account of their replication policy. When you enable priority replication, you can benefit from the associated Service Level Agreement if your source and destination account are located within the same continent. The SLA will guarantee that 99.0% of operations are replicated from the source container to the destination container of their OR policy within 15 minutes for the billing month. Please refer to the official SLA Terms for a comprehensive list of eligibility requirements. How to monitor SLA compliance for Geo and OR Priority Replication? Geo Priority Replication: Geo priority replication introduces a new metric, Geo Blob Lag. This metric allows users to monitor their Blob Replication lag, the number of seconds since the last full data synchronization between the primary and secondary region. This will allow users to track the SLA compliance of their GRS/GZRS account. If an account’s Geo Blob Lag remains within 900 seconds (15 minutes), they can confirm the data replication is within SLA. To learn more about the Geo Blob Lag metric view, Geo Blob Lag Metric. Object Replication Priority Replication: Replication Metrics for Object Replication is now Generally Available. These metrics empower users to troubleshoot replication delays and will help users with priority replication enabled monitor their SLA compliance. Metrics now supported are: Pending Operations: Tracks the total number of operations pending replication from the source to the destination storage account of your OR policy Pending Bytes: Tracks the total volume of data pending replication from the source to the destination storage account of your OR policy These metrics are grouped into various time buckets including 0-5 minutes, 10-15 minutes and > 24 hours. Users with OR priority replication that would like to ensure all their operations are replicating within 15 minutes; can monitor the larger time buckets (ex: 30 mins – 2hours or 8-24 hours) and ensure they are at zero or near zero. Users also have other options such as checking the replication status of their source blob. Users can check the replication status of a source blob to determine whether replication to the destination has been completed. Once the replication status is marked as “Completed,” the user can guarantee the blob is available in the destination account. How to get started? Getting started is simple, to learn more about the step-by-step process to opt-in to Geo priority replication: Azure Storage Geo Priority Replication - Azure Storage | Microsoft Learn.

If you are new to Azure Storage Actions, check out our GA announcement blog for an introduction. This post is for cloud architects, data engineers, and IT admins who want to automate and optimize data governance at scale. The Challenge: Modern Data Management at Scale As organizations generate more data than ever, managing that data efficiently and securely is a growing challenge. Manual scripts, periodic audits, and ad-hoc cleanups can’t keep up with the scale, complexity, and compliance demands of today’s cloud workloads. Teams need automation that’s reliable, scalable, and easy to maintain. Azure Storage Actions delivers on this need by enabling policy-driven automation for your storage accounts. With Storage Actions, you can: Automate compliance (e.g., legal holds, retention) Optimize storage costs (e.g., auto-tiering, expiry) Reduce operational overhead (no more custom cleanup scripts) Improve data discoverability (tagging, labeling) Real-World Scenarios: Unlocking the Power of Storage Actions Let’s explore 3 practical scenarios where Storage Actions can transform customers’ data management approach. For each, we’ll look at the business problem, the traditional approach, and how Storage Actions makes it easier with the exact conditions and operations which can be used. Scenario 1: Content Lifecycle for Brand Teams Business Problem: Brand and marketing teams manage large volumes of creative assets - videos, design files, campaign materials that evolve through multiple stages and often carry licensing restrictions. These assets need to be retained, frozen, or archived based on their lifecycle and usage rights. Traditionally, teams rely on scripts or manual workflows to manage this, which can be error-prone, slow, and difficult to scale. How Storage Actions Helps: Azure Storage Actions enables brand teams to automate the content lifecycle management using blob metadata and / or index tag. With a single task definition using an IF and ELSE structure, teams can apply different operations to blobs based on their stage, licensing status, and age without writing or maintaining scripts. Example in Practice: Let’s say a brand team manages thousands of creative assets videos, design files, campaign materials each tagged with blob metadata that reflects its lifecycle stage and licensing status. For instance: Assets that are ready for public use are tagged with asset-stage = final Licensed or restricted-use content is tagged with usage-rights = restricted Over time, these assets accumulate in your storage account, and you need a way to: Ensure that licensed content is protected from accidental deletion or modification Archive older final assets to reduce storage costs Apply these rules automatically, without relying on scripts or manual reviews With Azure Storage Actions, the team can define a single task that evaluates each blob and applies the appropriate operation using a simple IF and ELSE structure: IF: - Metadata.Value["asset-stage"] equals "final" - AND Metadata.Value["usage-rights"] equals “restricted” - AND creationTime < 60d THEN: - SetBlobLegalHold: This locks the blob to prevent deletion or modification, ensuring compliance with licensing agreements. - SetBlobTier to Archive: This moves the blob to the Archive tier, significantly reducing storage costs for older content that is rarely accessed. ELSE - SetBlobTier to Cool: If the blob does not meet the above criteria whether it’s a draft, unlicensed, or recently created, it is moved to the Cool tier. Once this Storage Action is created and assigned to a storage account, it is scheduled to run automatically every week. During each scheduled run, the task evaluates every blob in the target container or account. For each blob, it checks if the asset is marked as final, tagged with usage-rights, and older than 60 days. If all these conditions are met, the blob is locked with a legal hold to prevent accidental deletion and then archived to optimize storage costs. If the blob does not meet all of these criteria, it is moved to the Cool tier, ensuring it remains accessible but stored more economically. This weekly automation ensures that every asset is managed appropriately based on its metadata, without requiring manual intervention or custom scripts. Scenario 2: Audit-Proof Model Training Business Problem: In machine learning workflows, ensuring the integrity and reproducibility of training data is critical especially when models influence regulated decisions in sectors like automotive, finance, healthcare, or legal compliance. Months or even years after a model is deployed, auditors or regulators may request proof that the training data used has not been altered since the model was built. Traditionally, teams try to preserve training datasets by duplicating them into backup storage, applying naming conventions, and manually restricting access. These methods are error-prone, hard to enforce at scale, and lack auditability. How Storage Actions Helps: Storage Actions enables teams to automate the preservation of validated training datasets using blob tags and immutability policies. Once a dataset is marked as clean and ready for training, Storage Actions can automatically: Lock the dataset using a time-based immutability policy Apply a tag to indicate it is a snapshot version This ensures that the dataset cannot be modified or deleted for the duration of the lock, and it is easily discoverable for future audits. Example in Practice: Let’s say an ML data pipeline tags a dataset with stage=clean after it passes validation and is ready for training. Storage Actions detects this tag and springs into action. It enforces a 1-year immutability policy, which means the dataset is locked and cannot be modified or deleted for the next 12 months. It also applies a tag snapshot=true, making it easy to locate and reference in future audits or investigations. The following conditions and operations define the task logic: IF: - Tags.Value[stage] equals 'clean' THEN: - SetBlobImmutabilityPolicy for 1-year: This adds a write once, read many (WORM) immutability policy on the blob to prevent deletion or modification, ensuring compliance. - SetBlobTags with snapshot=true: This adds a blob index tag with name “snapshot” and value “true”. Whenever this task runs on its scheduled interval - such as daily or weekly, it detects if a blob has the tag stage = 'clean', it automatically initiates the configured operations. In this case, Storage Actions applies a SetBlobImmutabilityPolicy on the blob for one year and adds a snapshot=true tag for easy identification. This means that without any manual intervention: The blob is made immutable for 12 months, preventing any modifications or deletions during that period. A snapshot=true tag is applied, making it easy to locate and audit later. No scripts, manual tagging, or access restrictions are needed to enforce data integrity. This ensures that validated training datasets are preserved in a tamper-proof state, satisfying audit and compliance requirements. It also reduces operational overhead by automating what would otherwise be a complex and error-prone manual process. Scenario 3: Embedding Management in AI Workflows Business Problem: Modern AI systems, especially those using Retrieval-Augmented Generation (RAG), rely heavily on vector embeddings to represent and retrieve relevant context from large document stores. These embeddings are often generated in real time, chunked into small files, and stored in vector databases or blob storage. As usage scales, these systems generate millions of small embedding files, many of which become obsolete quickly due to frequent updates, re-indexing, or model version changes. This silent accumulation of stale embeddings leads to: Increased storage costs Slower retrieval performance Operational complexity in managing the timings Traditionally, teams write scripts to purge old embeddings based on timestamps, run scheduled jobs, and manually monitor usage. This approach is brittle and does not scale well. How Storage Actions Helps: Storage Actions enables customers to automate the management of embeddings using blob tags and metadata. With blobs being identified with tags and metadata such as embeddings=true, modelVersion=latest, customers can define conditions that automatically delete stale embeddings without writing custom scripts. Example in Practice: In production RAG systems, embeddings are frequently regenerated to reflect updated content, new model versions, or refined chunking strategies. For example, a customer support chatbot may re-index its knowledge base daily to ensure responses are grounded in the latest documentation. To avoid bloating storage with outdated vector embeddings, Storage Actions can automate cleanup with task conditions and operation such as: IF: - Tags.Value[embeddings] equals 'true' - AND NOT Tags.Value[version] equals ‘latest’ - AND creation time < 12 days ago THEN: - DeleteBlob: This deletes all blobs which match the IF condition criteria. Whenever this Storage Action runs on its scheduled interval - such as daily - it scans for blobs that have the tag embeddings = ‘true’ and is not the latest version with its age being more than 12 days old, it automatically initiates the configured operation. In this case, Storage Actions does a DeleteBlob operation on the blob. This means that without any manual intervention: The stale embeddings are deleted No scripts or scheduled jobs are needed to track. This ensures that only the most recent model’s embeddings are retained, keeping the vector store lean and performant. It also reduces storage costs by eliminating obsolete data and helps maintain retrieval accuracy by ensuring outdated embeddings do not interfere with current queries. Applying Storage Actions to Storage Accounts To apply any of the scenarios, customers create an assignment during the storage task resource creation. In the assignment creation flow, they select the appropriate role and configure filters and trigger details. For example, a compliance cleanup scenario might run across the entire storage account with a recurring schedule every seven days to remove non-compliant blobs. A cost optimization scenario could target a specific container using a blob prefix and run as a one-time task to archive older blobs.
