Backup and Disaster Recovery Planning
Business IT resource
Practical guide to recovery priorities, RPO/RTO, ransomware planning, restore testing, and disaster roles.
Backups are not a plan until recovery is tested
Many businesses believe they are protected because a backup job exists somewhere. That is not enough. A useful backup and disaster recovery plan defines what must be restored, how quickly it must return, who makes decisions during an outage, and how often recovery is tested.
This guide helps business owners and operations teams build a practical recovery plan for ransomware, hardware failure, accidental deletion, cloud account compromise, building issues, and vendor outages.
Define what matters first
Start with a business inventory, not a backup tool.
List:
- File shares and document libraries
- Microsoft 365 mailboxes, SharePoint, OneDrive, and Teams data
- Servers, virtual machines, and databases
- Line-of-business applications
- Accounting, legal, healthcare, construction, or professional services systems
- Network equipment configuration
- User devices that store important local data
- Vendor-hosted systems where backup responsibility is unclear
For each item, decide how long the business can operate without it.
Set RPO and RTO
Two recovery targets guide the plan:
- Recovery point objective: how much data the business can afford to lose.
- Recovery time objective: how quickly the system needs to be usable again.
Email may have one target. Accounting may have another. A project file server, medical system, legal document library, or construction management platform may require a different recovery plan.
Write these targets down before choosing tools. Otherwise, you may buy a backup product that does not match the business requirement.
Build layered backups
A strong backup strategy usually includes more than one layer.
Consider:
- Local backups for fast restores
- Cloud backups for site-level protection
- Immutable or protected backup copies to resist ransomware
- Microsoft 365 backup for mailboxes, OneDrive, SharePoint, and Teams
- Server image backups for full system recovery
- Configuration backups for firewalls, switches, and wireless controllers
- Periodic exports from vendor-hosted applications
The goal is not to collect tools. The goal is to make sure critical data can be restored even if one system, account, or location is compromised.
Plan for ransomware
Ransomware recovery requires more than a backup restore button.
Your plan should answer:
- How will infected systems be isolated?
- Who decides whether to shut down network access?
- How will clean backups be identified?
- How will administrator credentials be protected?
- How will communication happen if email is unavailable?
- Which systems must be restored first?
- How will restored systems be scanned before users reconnect?
Backups that use the same admin account as the rest of the environment may be vulnerable. Recovery planning should include identity security and privileged access controls.
Test restores
A backup that has never been restored is an assumption.
Create a testing cadence:
- Monthly file restore test
- Quarterly Microsoft 365 restore test
- Quarterly server or application restore test where practical
- Annual tabletop disaster recovery exercise
- Review after major infrastructure or cloud changes
Document the result of each test: what was restored, how long it took, who performed it, and what failed.
Assign roles before an outage
During an outage, people need clear roles.
Assign:
- Business decision owner
- Technical recovery owner
- Vendor communication owner
- Employee communication owner
- Customer or client communication owner
- Insurance or legal contact where applicable
This does not need to be complicated. A one-page incident role sheet is better than deciding everything during a crisis.
Keep the plan current
Review the plan when you add users, move offices, change cloud providers, replace a server, add a new business application, or change compliance requirements. Backup plans drift when business systems change.
Questions leadership should answer
Technical teams can design backups, but leadership has to set business priorities.
Answer:
- Which system must come back first?
- What is the maximum tolerable downtime for email, file access, accounting, and core applications?
- Who can approve emergency spending during an outage?
- Which clients, patients, vendors, or employees must be notified?
- Which data is regulated or contractually sensitive?
- What manual workaround is acceptable for one day?
- What workaround is acceptable for one week?
These answers turn backup settings into a recovery plan. Without them, the technical team may restore the wrong system first or spend time protecting low-priority data while critical operations remain down.
Signs the current backup plan is weak
Warning signs include no recent restore test, no Microsoft 365 backup, backup alerts going to an unmonitored mailbox, no written recovery order, no protected admin account, and no documentation for vendor-hosted applications. Any one of these can slow recovery when time matters.
What a recovery review should produce
A backup review should end with decisions, not just screenshots. At minimum, document which systems are protected, where backups are stored, how long data is retained, who receives alerts, which accounts administer backups, and when the last successful restore test happened. For each critical system, record the recovery order, the expected recovery time, and the person who can approve emergency changes.
Cloud systems need the same discipline. Microsoft 365, SaaS applications, accounting platforms, EHR systems, and line-of-business tools may have different export, retention, and recovery limits. If a vendor is responsible for part of recovery, keep the contact path and escalation process in the plan.
The final deliverable can be simple: an asset list, backup map, restore-test log, incident role sheet, and improvement list. Those documents help leadership understand what is protected and what still needs work.
Review after business changes
Backup plans should be reviewed after hiring growth, office moves, cloud migrations, server replacements, new compliance requirements, insurance renewals, major vendor changes, or new line-of-business applications. Each change can create data that is not protected by the old plan.
Do not assume a vendor-hosted system is automatically recoverable in the way your business expects. Ask what can be restored, how far back recovery goes, how long export takes, and who can approve urgent recovery work. The answers should be written into the plan before an outage.
