Who this is for

Owner-managed organisations with essential files on staff devices

Suitable where invoices, contacts, documents and email-related files sit across a small number of employee PCs or Macs and need a recoverable copy after loss, theft, hardware failure or malware. The National Cyber Security Centre highlights these operational data types in its small-organisation guidance.

Microsoft 365-based small teams

For teams whose essential records are mainly held in Exchange Online, OneDrive and SharePoint and need workload-specific backup and restoration rather than a device-only approach. Microsoft describes restore options for these Microsoft 365 workloads.

Small offices needing a separate local recovery copy

For offices that need an offline or locally held copy because internet reliability is limited, recovery should not rely on one cloud account, or shared files need local storage. Separation and restore testing remain important.

Backup buying priorities

Start by mapping essential records and where they are stored, then match the backup route to recovery, retention and access-control requirements.

Priority What to check Your needs
Recovery coverage List where contacts, invoices, documents, email and shared files are held. Check that the chosen service or device covers each location, supports earlier restore points where needed, and allows a representative restore test. I need the files and services that keep work moving to be recoverable after disruption, not simply a copy of one computer.
Protection from deletion Use separate backup administration credentials and MFA for destructive actions. For removable media, disconnect and store it separately; for cloud services, check version recovery and documented deletion controls. I do not want one compromised everyday account or connected device to reach every recovery copy.
Retention and personal data Calculate capacity for protected data, growth, backup frequency and version history. Set and review retention by data type, and check the processor contract when a supplier handles personal data. I need backup history that supports recovery without keeping staff, customer or contact data longer than necessary. The ICO says retention must be justifiable.
Access and supplier location Check role-based access, separate accounts, MFA and the provider’s processing and support locations. Review transfer documentation if a separate organisation outside the UK can access personal data. I need authorised staff to restore data without giving unnecessary access to backup contents or administration settings.

Pitfalls to avoid

  • Treating synchronisation or one connected location as a complete backup

    A lost, failed or infected device can leave an organisation without a usable copy, and ransomware may target backups and infrastructure. The National Cyber Security Centre notes that cloud and on-premises backups are not ransomware-resistant by default.

    Map essential systems and storage locations, then maintain at least one separately protected recovery copy. Disconnect removable media when it is not being written to, and restrict administration of NAS or cloud backup systems.

  • Buying capacity before setting retention and restore objectives

    Storage sized only for today’s live files may not allow for historical versions, growth or a full recovery copy. Retention also matters when backups contain personal data.

    Plan capacity around current protected data, expected growth, backup frequency, version history and required retention. Document why each category of personal data is retained and review the schedule.

  • Assuming a cloud provider takes over data-protection responsibilities

    The organisation remains responsible for assessing appropriate security. Where a backup supplier acts as a processor, the ICO requires a written contract; access by an organisation outside the UK can also require a restricted-transfer assessment.

    Review the provider contract, sub-processors, security controls, end-of-contract data handling, administrator access and processing or support locations before procurement.

  • Equating advertised drive speed with backup performance

    Quoted SSD speeds can depend on a compatible host, cable and interface. A fast portable drive remains vulnerable if it is the only copy or stays connected to a compromised computer.

    Check the computer’s USB capability, included cable and backup-software compatibility. Use transfer speed as one planning input, retain a separate backup location and test an actual restore.

Relevant backup brand references

Microsoft

Microsoft 365 Backup is a workload-specific route for organisations using Exchange Online, OneDrive and SharePoint within a Microsoft 365 tenant.

  • Microsoft states that it can restore SharePoint sites, OneDrive accounts and Exchange Online mailboxes, including selected tenant coverage and restore-point features.
  • It is not a backup for local endpoints, NAS data or non-Microsoft services. Confirm workload coverage, granular restore options, retention and current commercial terms.

Backblaze

Backblaze Business Backup is an endpoint-cloud-backup option for organisations seeking centrally managed protection for Mac and Windows computers.

  • According to Backblaze, its Business Backup offer includes automatic Mac and Windows endpoint backup, central management of restores and retention, and administrative controls.
  • Check device eligibility, exclusions, internet requirements, retention, restoration method, UK GDPR contractual terms and data-location implications for the organisation.

Samsung

Samsung Portable SSD T7 is a removable-storage component for an offline or separately stored backup rotation, rather than a complete backup arrangement by itself.

  • Samsung lists the 1TB T7 with USB 3.2 Gen 2, quoted sequential speeds up to 1,050 MB/s read and 1,000 MB/s write, plus USB-C-to-C and USB-C-to-A cables.
  • Samsung says maximum speeds require a compatible host, cable and UASP. Disconnect and store removable SSDs separately to create an isolated copy.

Frequently asked questions

How long should a UK small organisation retain backup copies containing personal data?

There is no single UK GDPR backup-retention period. The organisation should justify how long personal data is retained for its purposes, use standard retention periods where appropriate, review data periodically, and erase or anonymise it when it is no longer needed; separate legal or contractual duties may require different retention for business records.

Does UK GDPR require a backup provider contract?

Yes, where the organisation is a controller and the backup supplier processes personal data on its behalf as a processor. The ICO says a written contract or other legal act is required and should cover processing details, security, sub-processors, assistance, end-of-contract handling and audits or inspections.

Do cloud backups need to remain in the UK?

Not necessarily, but the organisation must assess the arrangement. The ICO explains that making personal data accessible to a separate organisation outside the UK can be a restricted transfer, so check processing locations, support access and transfer documentation before signing.

How often should a small organisation test restores?

Test restores regularly and match the interval to how quickly essential processes must resume and how often their data changes. The National Cyber Security Centre advises daily or weekly copies of essential information and regular testing that a backup can restore it.

Is an external SSD enough as the organisation’s backup?

No. An external SSD can be a useful separately stored copy, particularly where cloud-only backup is unsuitable, but it should not be the only recovery copy. Keep it secure and disconnected when not in use because connected devices can be affected by malware.
