Disaster Recovery Planning for Small Teams

What disaster recovery means

Disaster recovery is the part of planning that answers one question: if something major stops our systems from working, how do we get the business going again, and in what order?

The “disaster” does not have to be dramatic. A failed laptop drive, a broken internet line for two days, a hosting provider outage, ransomware, a burst pipe or the sudden loss of the one person who knows how things work can all qualify. The goal is not to predict the cause. It is to be ready for the effects: certain systems or data are unavailable.

This is related to, but different from, handling the first moments of a security event, which is the focus of an incident response plan. Incident response is about what to do when something goes wrong. Disaster recovery is about restoring service afterward.

Step 1: List what the business depends on

Write down the systems and services your daily work relies on. Think in terms of business activities rather than technology:

• Taking orders or bookings
• Sending invoices and receiving payments
• Email and phone
• Customer records
• Payroll
• The website
• Shared files and documents
• Specialist software or equipment

For each activity, note which system supports it, where it runs, who manages it, and what it depends on. Dependencies are easy to miss: an accounting tool may rely on the internet connection, a login system, and a bank connection. Mapping these shows what else breaks when one piece fails.

Step 2: Decide how long you can manage without each

For every item, ask two questions. Both have fancy names, but the ideas are simple.

How long can we be without it? This is often called the recovery time objective. Some systems can be down for a week with little harm. Others, such as the system that takes payments in a shop, may cause real trouble within hours.

How much recent work can we afford to lose? This is often called the recovery point objective. If your last backup was last night, you could lose a day of changes. Is that acceptable, or do you need more frequent copies?

Answers are judgments, not exact science. You can give them rough labels:

• Critical: needed within hours.
• Important: can wait a day or two.
• Can wait: can be restored within a week.

Discussing this with the whole team often brings surprises. A tool that seems minor to the owner might be essential to the person who ships orders.

Step 3: Match your protection to your priorities

Now compare what you have with what you need. If a critical system relies on a backup that runs weekly, but you can only afford to lose a day of data, there is a gap.

Typical measures include:

• Backups that follow the 3-2-1 approach and are tested. Without good copies, recovery is limited.
• Alternative ways of working for short outages, such as a mobile hotspot if the internet fails, or paper forms for a day.
• Spare equipment or a known way to obtain it quickly. A spare laptop set up with the basics can save days.
• Documentation of how things are configured, so someone else can rebuild them.
• Agreements with providers about support and recovery. Ask what a provider restores, how quickly, and what you must do yourself. If you rely on cloud storage, check how deleted and older versions of files are handled.

Spend effort in proportion to the importance of the system. It rarely makes sense to protect everything equally.

Step 4: Write a simple recovery plan

A small team’s plan can fit on one or two pages. Include:

1. Contacts: key staff, your IT support person, providers, your bank and insurer, with phone numbers that do not depend on your own systems.
2. Priority order: which systems to restore first, second and third.
3. Where things are: location of backups, installation files, license details, and the accounts needed to restore.
4. Access: how to reach passwords and recovery codes if the usual tools are unavailable, and who is authorized to use them.
5. Basic steps: for each critical system, the short sequence to bring it back.
6. Communication: who tells staff and customers what is happening, and how.

Keep a copy somewhere that you can reach if your main systems are down, such as printed or on a personal device.

Step 5: Test it

An untested plan is mostly guesswork. You do not need an elaborate drill. Try some of these at suitable intervals:

• Restore a file or a small system from backup and time how long it takes.
• Walk through a scenario on paper: “The office is unavailable for a week. What do we do on Monday morning?”
• Check that contact details are current and that people can actually find the plan.
• Confirm that the person who would do the recovery has the access and instructions they need.

Note what went wrong and fix it. The first test usually reveals gaps, which is exactly the point.

Step 6: Keep it current

Review the plan at least once a year and whenever something major changes: a new system, a move, a new supplier, or a change in staff. Out-of-date plans cause confusion because they point to systems that no longer exist or people who have left.

Things to be realistic about

• Recovery takes time, and the first attempt is often slower than expected.
• Some data may not be recoverable, which is why the question about acceptable loss matters.
• Insurance might help with costs but does not restore your systems.
• Plans cannot cover every situation, but a plan built around effects rather than causes tends to cope with surprises better.

The main benefit of this exercise is clarity. When something fails, the team already knows what matters most, who is doing what and where to find what they need.
