Disaster Recovery
Backup Strategy
Primary: Granola cloud storage
Secondary: Nightly export to company storage
Tertiary: Weekly archive to cold storage
Recovery Points:
- RPO: 24 hours (daily export)
- RTO: 4 hours (restore from export)
Failover Procedures
If Granola unavailable:
1. Manual notes during meeting
2. Record with backup tool
3. Transcribe post-meeting
4. Manual upload when restored
