Most small businesses do not discover the gaps in their disaster recovery the day they write a plan. They discover them at the worst possible moment: the server will not boot, the ransomware note is on the screen, or the office is closed by a burst pipe — and nobody is sure what happens next. A disaster recovery plan is simply the decisions made in advance, while everyone is calm. This checklist covers what a workable plan for a small business actually needs to contain.
Start with what matters: a systems inventory
You cannot recover what you have not listed. The plan opens with an inventory of the systems the business depends on: servers, cloud platforms, line-of-business applications, email, phones, and the data each one holds. For each entry, note where it lives, who uses it, what it connects to, and how long the business can function without it. That last column is the one that turns a list into a plan, because recovery order follows business impact, not alphabetical order. Dependencies matter as much as systems — the application nobody thinks about is usually connected to three that everybody does.
Set recovery targets you can defend
Two numbers drive every recovery design. The recovery time objective is how quickly a system must be back. The recovery point objective is how much data you can afford to lose, measured in time — an hour of entries, a day, a week. Set them per system, based on real impact: the system that takes orders may need an hour; the archive may comfortably allow a day. Targets set without this conversation tend to be either fantasy (everything back in fifteen minutes, at a price nobody agreed to pay) or meaningless (everything eventually). Once targets exist, backup design, infrastructure choices, and cost all have something concrete to answer to. Our disaster recovery service page describes how those targets get engineered in practice.
Backups: the part everything else stands on
The plan must state, plainly: what is backed up, how often, where the copies live, and who checks that jobs succeed. Keep copies separated — at least one off-site or in the cloud, isolated enough that the same incident cannot reach both the original and the copy. Ransomware made this non-negotiable: attackers look for backups first. And a backup that has never been restored is a hypothesis, not a safeguard. The plan should schedule restore tests and record their results, because the test is what converts hope into evidence. Our cybersecurity basics guide makes the same point from the security side.
People, roles, and the first hour
Technology is only half the document. The plan names who declares an incident, who leads the recovery, who talks to staff, and who talks to customers — with backups for each role, because disasters do not check vacation calendars. It also scripts the first hour: isolate affected systems rather than switching them off, preserve messages and logs instead of tidying them away, and get specialist help engaged early. In a suspected data incident, prompt advice matters because notification obligations can apply. Decisions like these are nearly impossible to invent under pressure and trivially easy to follow when written down.
Communication and the practical details
How do you reach staff if email is down? How do customers hear from you if the phones are? The plan carries an out-of-band contact list — personal mobiles held appropriately, a phone tree, an alternate channel — plus holding language for customers that is honest without being alarming. It also holds the unglamorous details that stall real recoveries: vendor and support contacts, license keys and where credentials are vaulted, insurance information, and the location of the plan itself. The plan must exist somewhere other than the server it describes recovering; keep copies off-site and in the cloud.
Test it, review it, keep it alive
A plan that is never exercised is a draft. Walk the team through a tabletop scenario periodically — a server failure on a Monday morning, a compromised mailbox on a Friday afternoon — and note where the document fails them. Test restores on a schedule. Review the whole plan whenever the business adds a system, changes a vendor, or grows into a new location, and at least annually regardless. Our managed IT services arrangements build that review rhythm into normal operations, which is how plans stay current instead of becoming memorabilia.
Frequently Asked Questions
What is the difference between a backup and a disaster recovery plan?
A backup is a copy of your data. A disaster recovery plan is the full set of decisions around it: what gets restored first, by whom, how quickly, and how the business communicates and operates in the meantime. Backups are one component of the plan, not a substitute for it.
How long should a disaster recovery plan be?
As long as it needs to be to be followed under pressure, and no longer. For most small businesses that is a focused document of several pages plus appendices for contacts and credentials — written for the worst day, not for a binder.
How often should we test our backups?
On a regular schedule, and after any significant change to your systems. A restore test proves the copy works, shows how long recovery really takes, and surfaces problems while they are still minor. Our cybersecurity basics article explains what a good test looks for.
Does a small business really need a written plan?
If losing a day of operations — or a day of data — would hurt, yes. The businesses that recover well are rarely the ones with the most technology; they are the ones whose decisions were made before the incident, by people who were not panicking.
