backup-recovery {Data} (v1.0)

"Data is the product. Model it for queries, secure it with rules, back it up daily."

Purpose

gcloud firestore export. Scheduled backups via Cloud Scheduler. Point-in-time recovery. Import procedures. Disaster recovery. [EXPLICIT] When to use: Database design, data management, or analytics within Firebase ecosystem.

Core Principles

1. Law of Queries: Design schema for read patterns. Firestore charges per read/write. [EXPLICIT]
2. Law of Rules: Security rules are mandatory. No collection without rules. [EXPLICIT]
3. Law of Backups: Production data gets scheduled backups. No exceptions. [EXPLICIT]

Core Process

Phase 1: Design data model from requirements.

Phase 2: Implement with security rules and indexes.

Phase 3: Test with emulator. Validate rules. Set up backups.

Validation Gate

• Schema designed for actual query patterns
• Security rules cover all collections
• Indexes defined for compound queries
• Backup strategy documented
• No SQL-style normalized design in Firestore

Usage

Example invocations:

• "/backup-recovery" — Run the full backup recovery workflow
• "backup recovery on this project" — Apply to current context

Assumptions & Limits

• Assumes access to project artifacts (code, docs, configs) [EXPLICIT]
• Requires English-language output unless otherwise specified [EXPLICIT]
• Does not replace domain expert judgment for final decisions [EXPLICIT]
