Can your small office restore its important files?

Your small office can only be confident about restoring important files when someone has checked what the backup contains and successfully retrieved a usable copy. A message saying that a backup finished is useful, but the practical question is: can you find, restore and open the information your business needs?

Start with a small, non-disruptive test. Choose a few representative files, restore them somewhere separate from your working documents, and check their contents. Record what worked, what was missing and who knows how to repeat the process. This is a check of those files, not a guarantee that everything can be recovered.

What the guidance establishes

The NCSC’s guidance on backing up your data recommends making copies of the information a business needs to operate. Its examples include emails, invoices, documents, contacts, customer information and website data. It also says you should know how to restore a backup and check that it contains your important information.

The guidance describes several reasons you might need a copy: a device could stop working, be lost or stolen, or have its data locked by ransomware or another virus. Ransomware is malicious software that can prevent access to data. These are general reasons to prepare, not evidence that your office has suffered an incident.

The NCSC describes both online storage and external storage devices as options. It recommends considering both for two backups, disconnecting external storage when it is not in use, and protecting online backups with two-step verification. The test below turns the advice about checking and restoring into a manageable office task.

What to do: run a safe sample restore test

1. Decide what the office actually needs

Write a short list of the information you would need to continue working without your usual computer. Consider current invoices, working documents, customer details, contacts and email. If your business depends on a website, include its information in the discussion too.

Next to each item, note where it lives and which backup is meant to contain it. Do not assume that a backup of one folder covers email, a website or every colleague’s files. Treat anything you cannot identify as a question to resolve, rather than a completed check.

2. Choose a small, meaningful sample

Pick a few files from the list: perhaps a recent document, an older invoice and a spreadsheet you use regularly. Include something recently changed so you can check whether the copy is current enough for your needs.

Use non-sensitive examples where possible. Agree what a successful result looks like before starting: the right file, a suitable date, readable contents and no changes to the live working version. Keep the first test small enough that someone can check each result carefully.

3. Find the restore instructions before clicking

Identify the service or device holding the backup, then find its instructions for restoring files. A restore means retrieving information from a saved copy. The NCSC links to provider instructions because the process depends on the system you use.

Check whether the instructions let you choose a separate destination. If the only apparent option is to replace existing files, restore a whole device or erase anything, pause. That is not a suitable first step for a simple sample test. Ask for help understanding the options before proceeding.

4. Restore without replacing working files

Where your backup system supports it, retrieve the sample into a clearly named test folder separate from your live documents. Avoid choosing your ordinary working folder as the destination.

Before confirming, read any warning about replacing files. Stop if the destination or effect is unclear. The aim is to examine a saved copy, not to alter the information your colleagues are using. If you cannot test safely with the options available, record that limitation and seek help.

5. Open and check the result

Open each restored file using the appropriate application. Check more than the filename: look for the expected text, figures or other contents, and whether the version is recent enough to be useful.

For information beyond ordinary files, such as email or website data, record whether you have tested it separately or still need advice. Restoring a document does not demonstrate that every other type of business information is covered. Mark each item as checked, missing or not yet tested.

6. Record the result and give someone responsibility

Keep a short record of the test date, backup used, sample chosen, destination and outcome. Note any missing files or unclear instructions, and assign someone to follow up.

Name the person responsible for backups and a second person who can locate the instructions. Record where authorised people can find access information, rather than putting passwords in a shared checklist. Agree when to repeat the test, including after changes to important devices, files or backup arrangements.

Check where your copies are kept

The NCSC says online backup is an option where internet access is reliable, and external storage is an option where it is not. It also recommends considering both methods in case one copy is lost or stolen, or the storage device fails.

For external storage, keep the device in a secure location and disconnect it when it is not being used. The NCSC warns that some viruses can also affect devices connected to an infected computer. As a practical planning step, consider whether a second copy could be kept securely away from the working device, with clear responsibility for its storage and access.

For online backups, enable two-step verification where the service supports it. This adds another verification step to signing in. Make sure authorised staff understand the service’s access arrangements before relying on it for a restore.

When to ask for help

Ask for help if nobody knows what is backed up, the sample is missing or unusable, or the restore process appears to require replacing live data. You should also pause if you cannot tell whether email, website information or colleagues’ documents are included.
