Azure Files Skill

This skill provides expert guidance for Azure Files. Covers best practices, decision making, limits & quotas, security, configuration, integrations & coding patterns, and deployment. It combines local quick-reference content with remote documentation fetching capabilities.

How to Use This Skill

IMPORTANT for Agent: Use the Category Index below to locate relevant sections. For categories with line ranges (e.g., L35-L120), use read_file with the specified lines. For categories with file links (e.g., [security.md](security.md)), use read_file on the linked reference file

IMPORTANT for Agent: If metadata.generated_at is more than 3 months old, suggest the user pull the latest version from the repository. If mcp_microsoftdocs tools are not available, suggest the user install it: Installation Guide

This skill requires network access to fetch documentation content:

• Preferred: Use mcp_microsoftdocs:microsoft_docs_fetch with query string from=learn-agent-skill. Returns Markdown.
• Fallback: Use fetch_webpage with query string from=learn-agent-skill&accept=text/markdown. Returns Markdown.

Category	Lines	Description
Best Practices	L35-L50	Best practices for Azure Files and Azure File Sync: DR/failover planning, server/topology changes, drive replacement, safe deprovision/recovery, and performance tuning for SMB/NFS and VDI/FSLogix.
Decision Making	L51-L70	Guidance for planning Azure Files deployments: choosing share types, redundancy and billing models, configuring File Sync and tiering, and selecting/migrating SMB/NFS solutions.
Limits & Quotas	L71-L78	Azure Files and File Sync limits: capacity, IOPS, throughput, tiers, quotas, and API throttling behavior to plan scaling and troubleshoot performance issues.
Security	L79-L107	Securing Azure Files: identity-based SMB/NFS auth, Kerberos/Entra/AD DS setup, NTFS/share permissions, encryption (CMK, TLS), firewalls, proxies, and secure client mounting.
Configuration	L108-L133	Configuring Azure Files and Azure File Sync: networking, VPN and private endpoints, performance and tiering, monitoring/metrics, redundancy, DFS integration, and file copy/soft delete settings.
Integrations & Coding Patterns	L134-L156	Patterns and code to build RAG apps over Azure Files using Haystack, LangChain, LlamaIndex, and vector DBs (Pinecone/Qdrant/Weaviate), plus .NET/Java/Python integration and auth.
Deployment	L157-L168	Guides for migrating and syncing data to Azure Files/Azure File Sync from NAS, Linux, GlusterFS, SMB/NFS shares, and moving File Sync resources safely across scopes.
