Enhanced data protection for Azure Files
Organizations rely on Azure Files for business-critical workloads such as VDI, SAP, and general-purpose file shares that hold their enterprise data. For these workloads, backup and disaster recovery are day-one requirements. Customers need a simple, scalable way to recover from an accidental change to production data, a regional disruption or a ransomware attack, both within a region and across regions. Today, we’re announcing new capabilities, in Public Preview, that expand business continuity and disaster recovery (BCDR) capabilities for Azure Files. They help customers recover from operational issues, strengthen regional resilience and protect critical file data from cyber threats: Vaulted backup for NFS shares: Protect NFS file shares with isolated recovery points through Azure Backup for protected, trusted recovery from cyber incidents. Revert snapshot: Roll an existing file share back to a known-good point in time, in place, without changing the endpoint or mount path for fast. This gives you fast recovery from operational issues. Azure Files-to-Azure Files copy and sync with Storage Mover: Use Azure Storage Mover to maintain a secondary copy of your SMB file share data in the Azure region of your choice, with scheduled incremental transfers to keep it current for disaster recovery. Together, these capabilities let customers build Azure Files resiliency in layers: roll back quickly, maintain secondary copies and recover from protected backups. Vaulted backup for Azure Files NFS shares Cyber recovery introduces another dimension to resiliency: When ransomware or another security incident compromises the production environment, organizations need protected recovery points and may need to validate recovered data before reconnecting it to production. Azure Files already supports vaulted backup for SMB shares. With this preview, that protection extends to NFS shares. Vaulted backup for Azure Files NFS shares adds an additional protection layer through Azure Backup. Recovery points are maintained separately from the production file share and managed through backup policies designed to support long-term retention, immutability, and cyber recovery objectives. Vaulted backup helps customers protect critical file data when: Recovery points need protection separate from production: Maintain protected recovery points separately from the production file share, adding another layer of protection for critical file data. Backup strategies require immutability: Support immutable backup strategies as part of the broader approach to protecting recovery points and meeting cyber recovery objectives. Data must be retained long term: Manage recovery points through backup policies designed to support long-term retention and meet the organization’s retention requirements. Ransomware resilience is a priority: Strengthen resilience with protected recovery points for recovery when ransomware or another security incident compromises the production environment.

Roll back quickly with Revert snapshot Operational mistakes are among the most common reasons applications need data recovery. A deployment can modify the wrong files, a configuration rollout can affect an entire namespace, or an administrator can accidentally overwrite critical content. Azure Files Revert Snapshot initially provides in-place recovery for data and applications hosted on SMB file shares, with NFS support coming next. Customers can select a point-in-time snapshot and restore the existing file share to that state while applications continue using the same file share, endpoint, and mount path. Common scenarios include: Failed application deployments: Roll back after a deployment modifies the wrong files. Incorrect configuration changes: Restore the share after a configuration rollout affects the namespace. Accidental mass modifications: Return to a point-in-time snapshot after unintended changes or overwrites. Development and test environment resets: Reset the file share to a selected snapshot. Azure Backup offers an integrated experience in the Azure portal restore blade to revert snapshots it manages. To participate in the Revert Snapshot preview, sign up here. Azure Files-to-Azure Files copy and sync with Storage Mover From disaster readiness and regional expansion to workload relocation and storage consolidation, customers need a simple, scalable way to copy and sync file data across storage accounts and Azure regions. Common use cases include Virtual Desktop Infrastructure (VDI) users maintaining secondary copies of FSLogix profiles and user data to support regional continuity, SAP and enterprise applications moving application data during regional expansion, organizations consolidating distributed content to simplify administration, and AI workflows placing datasets closer to AI and analytics compute to support distributed development and processing. Azure Files-to-Azure Files copy and synchronization with Azure Storage Mover gives customers a fully managed Azure service to copy data between SMB file shares across storage accounts, regions, and subscriptions (within the same tenant). They can also schedule incremental transfers to keep destination shares up to date. Customers can: Maintain secondary copies for business-critical workloads to an Azure region of choice. Schedule incremental synchronization of application data, user profiles, and shared content to another Azure region, helping organizations strengthen business-continuity and recovery planning. Copy or migrate file share data between regions: Copy data for regional expansion, datacenter transitions, or workload relocation. Consolidate file shares: Bring data together across storage accounts and regions to simplify management. Operate at scale with less overhead: Centrally schedule, monitor, and audit transfers instead of maintaining scripts or copy infrastructure. Azure Storage Mover reduces operational overhead with centralized scheduling, monitoring, auditing, metadata preservation, and orchestration for recurring file transfers.

As enterprises modernize applications and strengthen their security posture, identity is central to how applications access shared storage. Traditional identity models relying on account keys, stored credentials, or domain‑joined infrastructure add operational overhead and introduce security risks such as credential leakage, lack of identity attribution, and excessive privilege if shared keys are compromised. Today, we are excited to announce the General Availability (GA) of Managed Identity support for Azure Files over SMB, enabling applications and virtual machines to securely access Azure Files without secrets, passwords, or key distribution. Managed Identity support enables customers to meet modern enterprise security standards without reliance on storage account keys, streamlining how organizations securely enable file‑based application access and reducing the operational overhead of filing internal exceptions. New storage accounts can support secure, identity‑based SMB access out of the box, while existing deployments can get secure by enabling Managed Identity authentication. From web application workloads such as WordPress, to databases on Azure Kubernetes Service (AKS), to CI/CD pipelines, applications require secure access. In a world where security is foundational, continued reliance on key-based access conflicts with Zero Trust principles and least privilege access. What’s New In GA AKS Workload Identity Support AKS Workload Identity (preview) extends the traditional managed identity model for Kubernetes by shifting the identity from the node to pods. Instead of inheriting the identity of the underlying cluster, each Kubernetes pod can use its own federated identity, mapped directly to a Microsoft Entra ID principal. This feature enables: Pod-level identity isolation, rather than cluster-level Least-privilege access with secure RBAC Seamless scaling and redeployment, without identity reconfiguration No secrets, no key rotation, no credential injection When combined with Azure Files over SMB, Workload Identity allows AKS workloads to access shared file storage securely and natively per pod, using the same identity-driven model as cluster level managed identities. Now available with AKS 1.35, for customers specifically in the financial services industries, AKS Workload Identity enables per‑application, least‑privilege access to Azure Files without credentials, improving isolation and auditability. This allows regulated, stateful workloads to run securely on AKS while meeting strict compliance and regulatory requirements. Co-existence of Application Identities and end-user identity access Azure Files now enables both Managed Identity and end‑user access on the same storage account, with users and applications independently authenticated via Entra ID and authorized through a shared permissions model. This unified access model eliminates the need for duplicate storage or credentials, enabling secure collaboration, troubleshooting, and automation on shared data without compromising governance or compliance. This supports scenarios such as: Developers accessing the same file share as an application for debugging Admins managing content used by automated workflows Hybrid environments with user-driven and app-driven access Simplified Storage Account enablement via the Azure portal We have now added a dedicated Managed Identity property that makes enabling identity‑based SMB access simple and transparent via the Azure portal for new as well as existing storage accounts. With a single configuration at the storage account level, customers can allow applications to authenticate to Azure Files using Managed Identities. This portal experience supports incremental adoption, making it easy to modernize authentication while maintaining compatibility with existing user access and governance models. Get Started with Managed Identities with SMB Azure Files Start using Managed Identities with Azure Files today at no additional cost. This feature is supported on HDD and SSD SMB shares across all billing models. Refer to our documentation for complete set-up guidance. Whether provisioning new storage or enhancing existing deployments, this capability provides secure, enterprise‑grade access with a streamlined configuration experience.

We are thrilled to announce the General Availability (GA) of Vaulted Backup support in Azure Backup for Azure files - Standard tier to help seamlessly protect your data and applications hosted on Azure file share. With this release, you can now leverage vaulted backup integration to protect Standard SMB file shares. Azure Backup vaulted support for Azure file share provides enhanced data protection with the ability to configure snapshot and vaulted backup in a single policy to a secure backup location(Recovery Services vault) and support regional recovery. Vaulted backup provides advanced protection capabilities like ransomware protection, ability to restore even when file share is deleted which are missing with snapshot only backup. Vaulted backup solution seamlessly integrates with Azure File sync allowing File sync customers to protect data tiered to the cloud long-term in a cost-effective manner. In this blog post let’s explore how Azure Backup can enable robust data protection solution for businesses migrating and hosting applications on Azure file share. Security: Protection against Ransomware Ransomware or malware attack, continues to be a major threat to organizations worldwide, often leaving businesses at the mercy of cybercriminals demanding hefty ransom payments in exchange for access to their encrypted data. Vaulted backups provide a vital line of defense, ensuring that organizations can recover their data without giving in to ransom demands. Key features offered by vaulted Backups which protects against Ransomware: Isolation: Vaulted Backup data is isolated from your production storage accounts and stored in a separate tenant managed by Microsoft. This isolation helps safeguard your data against unauthorized tampering and ensures that your backups remain intact. Advanced security: Features like vault lock, multi-user authorization, and soft delete, which add additional layers of protection, ensuring that backups are immune to malicious deletion or tampering. Governance and security posture: Azure Backup integrates with the Business Continuity and Disaster Recovery (BCDR) security posture, allowing you to better manage and govern the security of your backups. This ensures that your backups meet the right level of protection and are recoverable when you need them most. Regulatory and compliance Azure File share enables users from industries like legal, finance, and health to store crucial business data. To comply with regulations and compliance checks, one will require offsite backups with long-term retention, which snapshots alone couldn't provide. With vaulted backup users can move snapshots to a Recovery Services Vault in the same Azure region as their primary storage, with options for cross-regional replication. This setup allows backup data to be retained for up to 99 years in low-cost, highly secure, immutable storage, meeting regulatory and compliance requirements during audits and legal holds. Furthermore, with the introduction of the new cross-subscription backup capability, organizations can allocate backup data to dedicated subscriptions. This feature allows customers to consolidate all backups into a single subscription, enhancing cost management and ensuring independent access control. It enables organizations to retain control over their data protection strategy while ensuring that each department or project adheres to its specific regulatory and security requirements. Enterprise Ready Vaulted backup support now enables adherence to the widely accepted 3-2-1 backup rule for Azure files protection. Azure Backup is well integrated with Azure Business Continuity Center that can offer centralized management to gain visibility, monitor jobs, alerts and reporting. How does 3-2-1 backup help? Human errors, insider threats, or stolen credentials can lead to critical data loss. File share snapshots serve as the first line of defense to restore your data. In case, where snapshots are not available, Vaulted Backups, stored securely outside of your primary storage account, provide an additional protected copy of your data. Additionally, the copy of the backup can be replicated to another region using GRS Geo-Redundant storage. A backup policy will enable you to manage the schedule and retention for both snapshots and vault copies. In the event of deletion whether accidental or malicious the restore process will first be initiated using snapshots. If snapshots are unavailable, recovery will proceed from the vault. If the primary region is down then one can restore from the secondary region with Cross Region restore option Getting started Here are three simple steps to help you get started with configuring vaulted backup for Azure File shares: Create a Recovery services vault: A vault is a management entity that stores backups and allows you to access and manage them. Create a backup policy: Backup policy enables you to configure the frequency and retention of backups based on your business requirements. Select the storage account and File shares to backup: You can choose to back up all File share or select specific File shares from the selected storage account depending on the criticality of the data they contain. Learn more about vaulted backup for File share here. Pricing and availability Vaulted backup for Azure File share standard is generally available in these regions. Vaulted backup for premium file shares will continue to be in public preview. You will incur a protected instance fee and charges for backup storage for both standard and premium shares from 1 st April 2025.

Faster server provisioning and improved disaster recovery for Azure File Sync server endpoints One of the most significant updates in Azure File Sync is the dramatic reduction in time required for provisioning new server endpoints. Previously, setting up a new server endpoint could take hours or even days, but with the v19 release and later, we’ve drastically cut down the time it takes to access data on the new server endpoint. This enhancement is critical for disaster recovery and is especially impactful when the Azure file share contains millions of files and folders. Furthermore, to enhance the management experience, we’ve introduced a Provisioning Steps tab in the portal, which allows you to easily determine when server endpoints are ready for use. You can now access data before syncing is complete. As users or applications navigate through their data, the system prioritizes relevant items for quicker access, eliminating the need to wait for a full download. These improvements help businesses quickly get their server endpoints up and running without long delays, improving overall operational efficiency. For more information, see Create an Azure File Sync server endpoint documentation. Improved sync performance for migrations & bulk updates Another exciting update for Azure File Sync is the substantial improvement in sync performance, now reaching up to 200 items per second. This marks a tenfold improvement over the past two years. This enhancement strengthens Azure File Sync's role as a seamless migration tool, enabling faster data transfers, especially those that require a large number of file changes (for example, when file permissions are changed). It's particularly beneficial for customers aiming to replace on-premises file servers and manage larger data sizes with Azure File Sync. Support for Windows Server 2025 Azure File Sync now supports Windows Server 2025 which has improved security, performance and manageability . The Azure File Sync extension for Windows Admin Center now supports Windows Servers from Windows Server 2025 down to Windows Server 2012 R2. This makes Azure File Sync suitable for a wide range of organizations regardless of their current server version. Azure File Sync facilitates the modernization of file servers, allowing organizations to seamlessly transition to newer servers running Windows Server 2025. The integration with Windows Admin Center (WAC) provides centralized management, offering a unified interface for managing configurations across multiple File Sync servers. This integration simplifies the management process, reducing complexity and saving time.

Azure Files provisioned v2 billing model for flexibility, cost savings, and predictability
We are excited to announce the general availability of the Azure Files provisioned v2 billing model for the HDD (standard) media tier. Provisioned v2 offers a provisioned billing model, meaning that you pay for what you provision, which enables you to flexibly provision storage, IOPS, and throughput. This allows you to migrate your general-purpose workloads to Azure at the best price and performance, but without sacrificing price predictability. With provisioned v2, you have granular control to scale your file share alongside your workload needs – whether you are connecting from a remote client, in hybrid mode with Azure File Sync, or running an application in Azure. The provisioned v2 model enables you to dynamically scale up or down your application’s performance as needed, without downtime. Provisioned v2 file shares can span from 32 GiB to 256 TiB in size, with up to 50,000 IOPS and 5 GiB/sec throughput, providing the flexibility to handle both small and large workloads. If you’re an existing user of Azure Files, you may be familiar with the current “pay-as-you-go” model for the HDD (standard) media tier. While conceptually, this model is simple – you pay for the storage and transactions used – usage-based pricing can be incredibly challenging to understand and use because it’s very difficult or impossible to accurately predict the usage on a file share. Without knowing how much usage you will drive, especially in terms of transactions, you can’t make accurate predictions about your Azure Files bill ahead of time, making planning and budgeting difficult. The provisioned v2 model solves all these problems – and more! Increased scale and performance In addition to the usability improvements of a provisioned model, we have significantly increased the limits over the current “pay-as-you-go” model: Quantity HDD pay-as-you-go HDD provisioned v2 Maximum share size 100 TiB (102,400 GiB) 256 TiB (262,144 GiB) Maximum share IOPS 40,000 IOPS (recently increased from 20,000 IOPS) 50,000 IOPS Maximum share throughput Variable based on region, split between ingress/egress. 5 GiB / sec (symmetric throughput) The larger limits offered on the HDD media tier in the provisioned v2 model mean that as your storage requirements grow, your file share can keep pace without the need to resort to unnatural workarounds such as sharding, allowing you to keep your data in logical file shares that make sense for your organization. Per share monitoring Since provisioning decisions are made on the file share level, in the provisioned v2 model, we’ve brought the granularity of monitoring down to the file share level. This is a significant improvement over pay-as-you-go file shares, which can only be monitored at the storage account level. To help you monitor the usage of storage, IOPS, and throughput against the provisioned limits of the file share, we’ve added the following new metrics: Transactions by Max IOPS, which provides the maximum IOPS used over the indicated time granularity. Bandwidth by Max MiB/sec, which provides the maximum throughput in MiB/sec used over the indicated time granularity. File Share Provisioned IOPS, which tracks the provisioned IOPS of the share on an hourly basis. File Share Provisioned Bandwidth MiB/s, which tracks the provisioned throughput of the share on an hourly basis. Burst Credits for IOPS, which helps you track your IOPS usage against bursting. To use the metrics, navigate to the specific file share in the Portal, and select “Monitoring > Metrics”. Select the metric you want, in this case, “Transactions by Max IOPS”, and ensure that the usage is filtered to the specific file share you want to examine. How to get access to the provisioned v2 billing model? The provisioned v2 model is generally available now, at the time of writing, in a limited set of regions. When you create a storage account in a region that has been enabled for provisioned v2, you can create a provisioned v2 account by selecting “Standard” for Performance, and “Provisioned v2” for File share billing. See how to create a file share for more information. When creating a share in a provisioned v2 storage account, you can specify the capacity and use the recommended performance. The recommendations we provide for IOPS and throughput are based on common usage patterns. If you know your workloads performance needs, you can manually set the IOPS and throughput to further tune your share. As you use your share, you may find that your usage pattern changes or that your usage is more or less active than your initial provisioning. You can always increase your storage, IOPS and throughput provisioning to right size for growth and you can also decrease any provisioned quantity after 24 hours have elapsed since your last increase. Storage, IOPS, and throughput changes are effective within a few minutes after a provisioning change. In addition to your baseline provisioned IOPS, we provide credit-based IOPS bursting that enables you to burst up to 3X the amount of provisioned IOPS for up to 1 hour, or as long as credits remain. To learn more about credit-based IOPS bursting, see provisioned v2 bursting. Pricing example To see the new provisioned v2 model in action, let’s compare the costs of the pay-as-you-go model versus the provisioned v2 model for the following Azure File Sync deployment: Storage: 50 used TiB For the pay as we go model, we need usage as expressed in the total number of “transaction buckets” for the month: Write: 3,214 List: 7,706 Read: 7,242 Other: 90 For the provisioned v2 model, we need usage as expressed as the maximum IOPS and throughput (in MiB / sec) hit over the course of an average time period to guide our provisioning decision: Maximum IOPS: 2,100 IOPS Maximum throughput: 85 MiB / sec To deploy a file share using the pay-as-you-go model, you need to pick an access tier to store the data in between transaction optimized, hot, and cool. The correct access tier to pick depends on the activity level of your data: a really active share should pick transaction optimized, while a comparatively inactive share should pick cool. Based on the activity level of this share as described above, cool is the best choice. When you deploy the share, you need to provision more than you use today to ensure the share can support your application as your data continues to grow. Ultimately this how much to provision is up to you, but a good rule of thumb is to start with 2X more than what you use today. There’s no need to keep your share at a consistent provisioned to used ratio. Now we have all the necessary inputs to compare cost: HDD pay-as-you-go cool (cool access tier) HDD provisioned v2 Cost components Used storage: 51,200 GiB * $0.015 / GiB = $768.00 Write TX: 3,214 * $0.1300 / bucket = $417.82 List TX: 7,706 * $0.0650 / bucket = $500.89 Read TX: 7,242 * $0.0130 / bucket = $94.15 Other TX: 90 * $0.0052 / bucket = $0.47 Provisioned storage: 51,200 used GiB * 2 * $0.0073 / GiB = $747.52 Provisioned IOPS: 2,100 IOPS * 2 * $0.402 / IO / sec = $168.84 Provisioned throughput: 85 MiB / sec * 2 * $0.0599 / MiB / sec = $10.18 Total cost $1,781.33 / month $926.54 / month Effective price per used GiB $0.0348 / used GiB $0.0181 / used GiB In this example, the pay-as-you-go file share costs $0.0348 / used GiB while the provisioned v2 file share costs $0.0181 / used GiB, a ~2X cost improvement for provisioned v2 over pay-as-you-go. Shares with different levels of activity will have different results – your mileage may vary. Typically, when deploying a file share for the first time, you would not know what the transaction usage would be, making cost projections for the pay-as-you-go model quite difficult. But it would still be straightforward to compute the provisioned v2 costs. If you don’t know specifically what your IOPS and throughput utilization would be, you can use the built-in recommendations as a starting point.
