The short answer
Backups answer "do we have a copy?" A recovery plan answers the questions that matter during an outage:
- What do we restore first, and what can wait?
- How long can each system be down (recovery time objective, RTO)?
- How much recent data can we afford to lose (recovery point objective, RPO)?
- Where will we restore to if the original servers, cloud account or office are unavailable?
- Who does what, and how do they reach each other if email is down?
- Have we proved it works, recently, by actually restoring?
The NIST Cybersecurity Framework makes the same point: it treats recovery as a function of its own, alongside prevention and detection, and expects recovery plans to be executed and improved after each event (NIST).
Why backups alone fall short
Common failures seen in real recoveries:
- Backups were not tested. Jobs reported success, but files were incomplete or could not be restored.
- Backups were reachable by the attacker. Ransomware encrypted or deleted backup copies stored on the same network with the same administrator credentials.
- Restores were too slow. Pulling terabytes from cloud storage over an office internet connection takes far longer than the business expected, and longer still on a congested or failing link.
- Dependencies were missing. Data was restored, but the application also needed a licence server, a database version, DNS records or identity services that no one had documented.
- SaaS data was assumed safe. Microsoft 365, Google Workspace or a line-of-business cloud application had no backup outside the provider's retention settings.
- No one knew the order. Staff restored what they could, not what the business needed first.
Set recovery objectives with the business
RTO and RPO are business decisions, not IT settings. For each important system, ask the people who depend on it:
| System | What stops if it is down? | Acceptable downtime (RTO) | Acceptable data loss (RPO) |
|---|---|---|---|
| Accounting or ERP | Invoicing, payments, payroll | Agreed with finance | Agreed with finance |
| Email and files | Most communication and work | Agreed with leadership | Agreed with leadership |
| Line-of-business application | Service delivery | Agreed with operations | Agreed with operations |
Shorter objectives cost more: more frequent backups, standby systems, faster storage and more testing. The plan should record the trade-off the business chose.
Protect backups from ransomware
The widely used 3-2-1 rule means three copies of your information, on two different media types, with one copy off site, and CISA's ransomware guidance recommends keeping backups offline, disconnected from the network, so an attacker cannot reach them (CISA). In practice:
- Keep at least one copy offline or immutable (write-once storage that cannot be altered or deleted for a set period).
- Use separate credentials for the backup system, with MFA, not the same domain administrator accounts attackers target.
- Encrypt backups, and store the keys where you can reach them during an incident.
- Monitor backup jobs and alert on failures and unusual deletions.
CISA's ransomware guide covers preparation and recovery steps in more detail (CISA).
Do not forget cloud and SaaS data
Cloud providers keep their services running, but restoring your data after accidental deletion, a malicious insider or ransomware in a synced folder is usually your responsibility. For Microsoft 365, options include Microsoft 365 Backup, a pay-as-you-go service covering SharePoint, OneDrive and Exchange Online (Microsoft Learn), or third-party tools that keep copies outside Microsoft's service. Check every critical SaaS application for its export and restore options.
What a recovery plan contains
NIST's contingency planning guide describes a structured approach: business impact analysis, preventive controls, recovery strategies, plan documentation, testing and training, and maintenance (NIST SP 800-34). A practical plan for a small or mid-sized organisation includes:
- Scope and triggers: which events activate the plan and who declares it.
- Contacts: internal roles, IT providers, key vendors, insurer, legal adviser, stored somewhere reachable offline.
- System priorities with RTO and RPO for each.
- Dependencies for each system: identity, network, DNS, licences, databases, integrations.
- Step-by-step restore procedures, written so a competent person who did not build the system can follow them.
- Alternative arrangements: where people work, how they communicate, how the site is powered if the grid and generator fail, which second internet link is used, and what manual workarounds exist.
- Communication templates for staff, clients and, if personal data is involved, the notifications described in personal data breach reporting in Nigeria.
- Testing schedule and results.
Test, then test again
A test is the only evidence that recovery works. Mix three types:
- File and item restores, often, as routine checks.
- Full system restores of important systems to an isolated environment, at least annually, timed against the RTO.
- Tabletop exercises that walk leaders through a scenario, such as ransomware on a Monday morning, to test decisions and communication.
Record how long each test took and what went wrong, then update the plan.
A hypothetical accounting firm backs up its file server nightly to a device in the same office and assumes it is covered. A recovery review finds three gaps: the backup device uses the same administrator password as the server, Microsoft 365 mailboxes have no backup, and nobody has timed a full restore. The firm adds an immutable off-site copy with separate credentials, a Microsoft 365 backup, and a test restore of the practice management system before the year-end filing rush. The test shows the restore takes most of a working day, so the partners agree an RTO that reflects that, and budget for a faster option next year.
Recovery readiness worksheet
Objectives
- Critical systems listed in priority order
- RTO and RPO agreed with business owners for each
Backups
- 3-2-1 approach with an offline or immutable copy
- Separate, MFA-protected credentials for the backup system
- SaaS data (Microsoft 365, Google Workspace, other cloud apps) covered
Plan
- Dependencies documented for each critical system
- Step-by-step restore procedures written
- Contacts and plan stored where they are reachable offline
- Communication templates prepared
Testing
- Routine file restores scheduled
- Full restore of critical systems tested and timed
- Tabletop exercise held with leadership
Limitations
A recovery plan must be maintained: every new system, provider or office changes it. Review it at least annually and after any significant change. If you need backup, disaster recovery or restore testing set up or reviewed, see our backup and disaster recovery service.
