Creating an effective data recovery plan is crucial for any business to protect their data in the event of hardware failure, data corruption, cyber attacks, or natural disasters. Having a solid data recovery plan in place can help minimize downtime and data loss in these situations.
Why is a data recovery plan important?
A data recovery plan is important for several key reasons:
- It helps ensure business continuity in the event of data loss or systems failure
- Minimizes downtime and productivity loss from data recovery efforts
- Speeds up the process of restoring access to data after an incident
- Reduces the risk of permanent data loss which can be catastrophic
- Demonstrates due diligence in protecting critical company data assets
Without a plan, data recovery efforts can become complex, drawn out and expensive. The aftermath of an incident may result in significant downtime if data cannot be accessed or restored quickly.
How to build a data recovery plan
Building an effective data recovery plan involves several key steps:
- Identify critical data and systems – Determine which data and systems are most critical for maintaining business operations. This typically includes customer data, financial records, product information, order databases etc.
- Establish RTOs and RPOs – Define your Recovery Time Objective (RTO) and Recovery Point Objective (RPO) for critical resources. The RTO is the time to restore access after an outage, while RPO defines the maximum acceptable data loss.
- Choose backup methodology – Select an appropriate backup strategy such as full backups, incremental, differential, snapshots etc. A hybrid approach is common for optimal recovery flexibility.
- Define backup schedule and retention – Configure backup frequency and retention policies aligned with RTO and RPO. Retaining backups for longer periods gives you more recovery options.
- Secure and catalogue backups – Ensure backups are securely stored, encrypted and catalogued so they can be easily located and identified when needed.
- Document detailed procedures – Document step-by-step actions required to recover data and systems from backups. This facilitates faster execution during high-stress recovery scenarios.
- Specify recovery roles – Clearly identify responsibilities for data recovery execution and decision making across technology, business and management teams.
- Integrate with business continuity plan – Align data recovery procedures with your broader business continuity plan. Test integrated execution during scheduled exercises.
- Regularly test and audit – Perform periodic walkthroughs and tests to validate the effectiveness of your data recovery plan. Identify gaps and opportunities for improvement.
Choosing the right backup strategy
A key component of the data recovery plan is selecting an optimal backup strategy aligned with business needs. Some considerations for common backup methodologies:
Full backups
- All data copied in periodic batches
- Larger storage requirements
- Faster restore times for entire systems
- Infrequent backup cycles (weekly)
Incremental backups
- Only changed data copied after initial full backup
- Smaller storage needs
- Faster daily backup cycles
- Slower recovery when piecing backups together
Differential backups
- Copies data changed since last full backup
- Balances storage and recovery time
- Daily backups capturing latest changes
Snapshot backups
- Point-in-time copies of data or virtual machines
- Allows instant restore to previous snapshot
- Limited retention period
- Effective for recovering from data corruption
A hybrid approach often provides the most flexibility. For example, full weekly backups combined with daily incrementals and snapshots.
Best practices for backup retention
Retention policies dictate how long backup data is stored before being deleted. Some guiding principles for defining optimal retention:
- Align retention with RPO – Keeping backups as long as needed to meet RPO requirements
- Balance storage costs – Storing backups incurs ongoing storage expenses which grows over time
- Accommodate likely scenarios – Most restore needs occur within the past few weeks/months
- Plan for worst case – Keep some longer term backups for handling worst case scenarios
- Meet compliance rules – Adhere to regulatory retention mandates if applicable
Typical retention schemes may keep backups for:
- Days to weeks – Common recovery timeframe
- Months – Handle most major outages
- Years – Meet compliance rules and unlikely scenarios
How to secure and manage backups
Properly managing backups is critical for ensuring they remain viable and recoverable when needed. Key aspects include:
- Secure storage – Use physically secure facilities along with access controls for backup archives
- Encryption – Encrypt backup data to prevent unauthorized access
- Offsite storage – Store some backups remotely to support recovery from location-specific failures
- Media handling – Use barcode labels and run disk maintenance routines to sustain media integrity
- Cataloging – Maintain detailed records of backups including contents, locations and restoration procedures
- Monitoring – Get alerts on failed backups and available capacity to identify issues promptly
- Rotation – Swap media on a schedule to spread wear and tear across multiple units
Documenting data recovery procedures
Complete documentation of the step-by-step recovery process for critical systems allows for more effective execution during high-pressure recovery scenarios. Key elements to document include:
- Recovery instructions – Precise steps required to restore from specified backup types
- Recovery sequences – Order to recover integrated systems and data stores
- Recovery point selection – Guidelines for how recent a backup should be selected
- Recovery roles – Who authorizes restoration and who executes on instructions
- Recovery locations – Where restoration takes place – onsite or alternate facility
- Integrated testing – How documentation is aligned with testing procedures
Having this information documented ahead of time aids recovery teams by removing guesswork and speeding up response times.
Defining data recovery roles and responsibilities
Successfully executing on a data recovery plan involves close coordination between different members across technical and business roles. Key responsibilities should be established for:
- CIO/CTO – Provides overall direction on recovery priorities and decision making
- IT managers – Oversees technical resources needed for data restoration
- Storage admins – Implements the recovery process within data storage systems
- DBAs – Restores database backups as needed
- Security officer – Ensures continued data security during recovery operations
- Business managers – Represents business interests in recovery decisions
- PR/communications – Manages external communications around data recovery efforts
- Counsel – Provides legal guidance around data recovery scenarios
Ensuring these stakeholders understand their role avoids confusion and delays during actual recovery efforts.
Integrating with business continuity planning
To be fully effective, the data recovery plan should seamlessly integrate with broader business continuity planning. Key aspects to align include:
- Incident response – Data recovery procedures kick off along defined incident response protocols
- Escalation – Integrates data recovery task triggers into overall escalation procedures
- Failover – Coordinates timing of data restoration with business process failover
- Crisis teams – Incorporates data recovery roles into crisis management teams
- Exercises – Includes data recovery steps within testing of business continuity plan
- Facilities – Aligns data center and recovery site capabilities needed for restoration
- Communications – Ensures stakeholders are consistently updated around recovery status
Testing and auditing the data recovery plan
Once created, the data recovery plan should be periodically tested and audited to identify potential enhancements. Key activities include:
Walkthroughs
Detailed walkthroughs of recovery procedures to validate completeness, accuracy and sequencing of documentation.
Simulations
Controlled simulations of different data loss and outage scenarios to test response capabilities in a risk-free environment.
Functional testing
End-to-end validation that recovered data is complete and systems are functionally restored as expected.
Recovery testing
Recovering copies of production data from backups into a test environment to verify recoverability.
Audit
In-depth audits assessing the performance of backup and recovery tools and identifying opportunities for enhancement.
Testing activities should occur on a quarterly or bi-annual basis to ensure the highest level of readiness.
Key metrics for data recovery plans
Establishing metrics around data recovery helps quantify readiness and monitor for improvement opportunities. Key metrics include:
| Metric | Target |
| Recovery Time Objective | 4 hours |
| Recovery Point Objective | 24 hours |
| Backup success rate | 99% |
| Time to recover from backups | 2 hours |
| Test recovery successes | 100% |
| Plan review frequency | Semi-annual |
By regularly measuring against targets, gaps in capabilities can be identified and addressed.
Data recovery plan templates
Using a template can help ensure all key elements are covered when developing a data recovery plan. Common sections include:
- Introductory summary
- Business impact analysis
- Recovery objectives
- Backup strategy and technology
- Recovery procedures
- Roles and responsibilities
- Communications plan
