Your backup software says last night’s job succeeded. But if your business lost access to its systems tomorrow morning, could you actually restore the information needed to operate?
A successful backup job is reassuring. It is not proof that your organization can recover from a ransomware attack, hardware failure, or accidental deletion. The real test is whether you can restore the right data, in usable condition, within an acceptable amount of time.
What failed recovery costs a business
Imagine losing access to customer records, scheduling, financial data, or essential files for several days. Employees may be unable to serve customers. Orders and invoices could be delayed, sales lost, and contractual commitments missed. Even if the files eventually come back, the interruption can be expensive.
That is why backup and disaster recovery planning is a business continuity issue, not simply an IT checklist.
Follow a practical backup strategy
CISA recommends the 3-2-1 approach: keep three copies of important data, store them on two different types of media, and keep at least one copy offsite. It also recommends automatic, regular backups; a mix of onsite and remote copies; protections such as offline copies, encryption, and physical security; and scheduled test restores. Its guidance includes checking whether you can roll back data at least seven days when necessary.
The important point is not just how many backup copies exist. It is whether those copies are protected and can be used when production systems are unavailable.
Test restores, not just backup notifications
A dashboard might show that every backup completed successfully while hiding critical gaps. Perhaps the backup excludes an important database. Perhaps the recovery credentials are unavailable. Or perhaps restoring a server takes far longer than anyone expected.
Choose an important file set, mailbox, or system and perform a controlled test restore. Confirm that the recovered information is complete and usable. Document the steps, the person responsible, how long the recovery took, and what needs fixing. Test without putting production data at risk.
Set recovery expectations before an incident
Two targets can guide decisions. A recovery point objective (RPO) defines how much recent data the business can afford to lose. A recovery time objective (RTO) defines how long an important system can remain unavailable. Leadership should help set these targets based on operations and customer commitments; IT should test whether the recovery approach can meet them.
Three questions to ask this month
- When did we last restore a file or system—not just confirm the backup job ran?
- Do we have a protected backup copy that an attacker with access to our normal environment cannot easily alter or delete?
- Who is accountable for testing recovery, documenting results, and addressing gaps?
Where to start
Inventory what is backed up, how frequently copies are made, where they are stored, and when they were last restored. Even a spreadsheet is a useful first step. Then run one controlled test, time the process, and fix the most serious gaps.
