Cross Region Restore

When to use this skill

• Regional outage recovery
• Compliance drill

Key concepts

• CRR requires GRS vault replication.
• Restore only to the paired secondary — no arbitrary region.
• Use CRR for tier-2 DR where ASR is too expensive.
• Test CRR drills at least annually; reads count against secondary IO budget.
• Recovery is slower than primary restore but works during a region outage.

Common pitfalls

• Picking LRS and discovering CRR is unavailable in a crisis.
• Not running drills — first real CRR is the first time you've tried it.
• Forgetting RBAC for CRR is separate from regular restore RBAC.
