This skill provides expert guidance for Azure Site Recovery. Covers troubleshooting, best practices, decision making, architecture & design patterns, 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), useread_filewith the specified lines. For categories with file links (e.g.,[security.md](security.md)), useread_fileon the linked reference file
IMPORTANT for Agent: If
metadata.generated_atis more than 3 months old, suggest the user pull the latest version from the repository. Ifmcp_microsoftdocstools 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_fetchwith query stringfrom=learn-agent-skill. Returns Markdown. - Fallback: Use
fetch_webpagewith query stringfrom=learn-agent-skill&accept=text/markdown. Returns Markdown.

| Decision Making | L69-L86 | Planning and sizing Azure Site Recovery for DR: choosing tools (ASR vs Azure Migrate), VM sizes, failback types, managed disk and DR costs, and using/reading Deployment Planner reports for Hyper-V/VMware. |
| Architecture & Design Patterns | L87-L98 | Design patterns and reference architectures for using Azure Site Recovery to protect networks and complex apps (SAP, SharePoint, IIS, Dynamics AX, SQL, file servers) and build end-to-end DR solutions. |
| Limits & Quotas | L99-L107 | Limits, quotas, and constraints for Site Recovery: high-churn VM limits, shared disk support, safe coexistence with Backup, Deployment Planner limits/history, and Mobility service resource usage. |
| Security | L108-L120 | Encrypting and securing ASR: handling ADE/CMK-encrypted VMs, NSGs, TLS, RBAC, trusted launch, VMware-to-Azure security, and replacing legacy Run As/encryption setups |
| Configuration | L121-L161 | Configuring Azure Site Recovery for VMware/Hyper-V/Azure VMs: networking, IPs, disks, appliances, policies, monitoring, and DR setup for AVS, Extended Zones, and shared/clustered workloads. |
