Disaster Recovery (DR)
Abbreviation: DR
Pronunciation: dih-ZA-stur ree-KUV-er-ee
Also known as: Disaster Recovery, DR
Definition
Disaster recovery addresses events that make normal systems, facilities, people, credentials, or data unavailable.
Overview
How it works and why it matters
Disaster recovery is a rehearsed process for restoring essential operations and trusted data after an outage, corruption, compromise or physical failure. Recovery objectives include how much data loss is acceptable (RPO) and how long service may remain unavailable (RTO). Wallet keys, payment state and ledger integrity require different safeguards.
Important technical and operational details
Examples include cyberattacks, infrastructure failure, lost signing devices, regional outages, corrupted databases, compromised keys, or the failure of an essential service provider.
Recovery must restore more than application access. Teams may need to reconstruct balances, reestablish signing authority, validate addresses, replace infrastructure, reconcile pending transactions, rotate secrets, and communicate controlled status changes. Recovery objectives should distinguish acceptable data loss from acceptable service downtime.
A reliable program defines critical services, dependencies, recovery priorities, responsible roles, backup locations, alternate signers, communication channels, and evidence requirements. Procedures should be tested through realistic exercises and updated after system changes. Restored systems must be verified before transaction authority resumes, because rapid but unvalidated recovery can repeat or amplify the original incident.
Disaster recovery is the coordinated process for restoring wallet, custody, treasury, and supporting operations after a severe disruption or loss event. Effective handling of Disaster Recovery (DR) connects detection, triage, preservation, containment, eradication, recovery, communication, regulatory assessment, and lessons learned through one auditable timeline. Disaster Recovery (DR) should distinguish an alert, suspected event, confirmed incident, material impact, and restored service because each state requires different decisions and notifications. Disaster recovery must restore verified control, records, and transaction capability, not merely bring an application back online.

Example
A payment server loses its database during a cloud outage. A backup restores invoices but excludes the most recent 15 minutes. The team replays authenticated payment events and reconciles on-chain receipts before reopening fulfillment, rather than pretending the restored database is current.
Comparison
Backup is only one component of DR. A backup that cannot be restored, lacks credentials or reproduces compromised keys does not prove recoverability. Test restore procedures and decision authority regularly.
Key Takeaway
Recovery succeeds only after restored systems and financial records are trustworthy again.
