Business Continuity Planning: A Practical Guide

• No prioritization: everything is labeled "critical," so nothing gets the right level of protection.
• Unrealistic targets: RPO and RTO goals that don't match the actual backup/recovery infrastructure.
• Tribal knowledge: recovery steps exist only in someone's head, not in documentation.
• Untested plans: the plan looks good on paper, but nobody has ever tried to execute it.
• No communication plan: during an incident, staff and customers are left guessing about timelines and next steps.
• Stale documentation: the plan was written three years ago and hasn't been updated after migrations, vendor changes, or staff turnover.

Two terms define your recovery strategy: Recovery Point Objective (RPO) and Recovery Time Objective (RTO).

• RPO (Recovery Point Objective): How much data loss is acceptable. If your last backup was 24 hours ago and the system fails now, you lose 24 hours of work. That's your RPO. For some systems (like email), 24 hours might be fine. For others (like order processing), even an hour might be too much.
• RTO (Recovery Time Objective): How long you can tolerate downtime before the business is seriously impacted. If your accounting system goes down, can you wait 4 hours? 1 hour? 15 minutes? That's your RTO.

Quick example: Your CRM goes down at 9:00 AM.

• Target RTO: 4 hours (back online by 1:00 PM).
• Target RPO: 1 hour (up to 1 hour of data loss acceptable).
• Reality check: backups run every 24 hours and restores take 6 hours.

That gap means your targets do not match your infrastructure. Fix the mismatch before an incident.

A Business Impact Analysis (BIA) is the process of identifying which systems and processes are most critical to your operations. It answers the question: "If this system goes down, how long until the business is seriously impacted?"

How to run a basic BIA:

1. List your systems: Start with the obvious—email, file servers, line-of-business apps, payment processing, customer-facing systems. Don't forget dependencies like identity providers, DNS, and network infrastructure.
2. Ask the impact question: For each system, ask: "If this goes down right now, how long until we have a serious problem?" Serious means revenue loss, compliance violation, customer impact, or operational halt.
3. Assign a tier: Group systems into tiers based on impact:
   • Tier 1 (Critical): Business stops within hours. Examples: order processing, payment systems, customer-facing apps.
   • Tier 2 (Important): Business is impaired within 1-2 days. Examples: email, file shares, internal collaboration tools.
   • Tier 3 (Standard): Business can function for several days without it. Examples: reporting systems, archival data, internal wikis.
4. Involve the right people: IT knows the systems, but business leaders know the impact. A 15-minute conversation with department heads will reveal which systems actually matter.

The output is a simple prioritization worksheet: a list of systems, their tier, and their RPO/RTO targets. This becomes the foundation for your recovery strategy.

Once you've tiered your systems, you can design recovery strategies that match the risk and budget:

• Tier 1 (Critical): Requires aggressive RPO/RTO targets (minutes to hours). Strategies include high-availability configurations, real-time replication, hot standby systems, or cloud failover. These are expensive, so you only apply them where the business impact justifies the cost.
• Tier 2 (Important): Moderate RPO/RTO targets (hours to 1 day). Strategies include frequent backups (hourly or daily), documented restore procedures, and tested recovery paths. Most mid-market systems fall here.
• Tier 3 (Standard): Relaxed RPO/RTO targets (days). Strategies include standard backup schedules (daily or weekly) and basic restore documentation. These systems are important, but downtime is tolerable.

The goal is to match investment to impact. Over-protecting Tier 3 systems wastes money. Under-protecting Tier 1 systems risks the business.

1. Run the BIA: Identify critical systems and assign tiers (see above).
2. Set RPO/RTO targets: For each tier, define acceptable data loss and downtime. Be realistic—don't set targets your infrastructure can't meet.
3. Document recovery procedures: For Tier 1 and Tier 2 systems, write down the steps to restore them. Include: where backups are stored, how to access them, dependencies (identity, DNS, networking), and who to contact.
4. Build a communication plan: Define who communicates with staff, customers, and vendors during an incident. Include templates for status updates and escalation paths.
5. Test the plan: Run tabletop exercises (talk through a scenario) and live recovery tests (actually restore a system). Update the plan based on what you learn.
6. Review and update: Revisit the plan after major changes (migrations, new systems, staff turnover) and at least annually.

• Quarterly: Run a tabletop exercise—walk through a scenario (e.g., "the file server is down") and talk through the recovery steps. This reveals gaps in documentation and communication.
• Semi-annually: Test a live recovery for a Tier 1 or Tier 2 system. Time it. Document what worked and what didn't.
• After changes: Update the plan after migrations, new systems, vendor changes, or staff turnover.
• Keep it simple: Save a one-page log of tests (date, scenario, participants, outcome, follow-ups). This is evidence for audits and reviews.

It's the last day of the month. Your accounting team is closing the books. At 2pm, the accounting system crashes. The database won't start.

Now the questions start:

• How critical is this system? Is it Tier 1 (business stops) or Tier 2 (business is impaired)? If you haven't done a BIA, you're guessing.
• What's the RPO? When was the last backup? If it was last night, you've lost a full day of month-end entries. Is that acceptable?
• What's the RTO? Can you wait 4 hours for a restore? Or do you need it back in 1 hour? If you don't have a target, you don't know if you're on track.
• Where are the recovery steps? Is there documentation, or does one person know how to restore it? What if they're out of the office?
• What about dependencies? The database came back, but the accounting software won't connect. Did you restore the right version? Are the credentials correct? Is the network configuration right?
• Who do you tell? The CFO is asking for an update. The accounting team is waiting. Do you have a communication plan, or are you making it up as you go?
• What happens if you miss the deadline? If you can't close the books on time, what's the business impact? Regulatory penalties? Delayed reporting? Investor concerns?

This single scenario—a database failure during a critical business process—exposes gaps in: system prioritization, recovery targets, documentation, communication, and testing. That's why business continuity planning matters.

These are illustrative examples. Choose tools that fit your environment and requirements.

Business continuity planning is more about process than tools. The most important "tool" is a clear prioritization framework and tested recovery procedures. That said, common tools for documentation and testing include:

• Spreadsheets or simple databases for tracking systems, tiers, RPO/RTO targets, and test results.
• Collaboration platforms (Microsoft Teams, Slack, SharePoint) for storing recovery documentation and communication templates.
• Backup and disaster recovery platforms that support your RPO/RTO targets (see the Backup & DR Testing guide for more).

The right approach depends on your environment, budget, and risk tolerance. The key is to start simple and iterate based on what you learn from testing.
