Choose cloud backup when internet access is reliable and an off-site copy is needed; use disconnected local storage when uploads are impractical, and consider both when critical files need another recovery path. A NAS with backup software can help manage several laptops, but it needs secure administration and an isolated or off-site copy. The National Cyber Security Centre advises against relying on cloud synchronisation or deleted-file features alone to back up critical business data.
If email, documents or invoicing live in an everyday cloud workspace, plan how to recover essential data independently of that workspace. The National Cyber Security Centre advises against treating file versions and deleted-item features as the only backup for critical data.
A removable drive or local NAS copy can provide a backup route when online transfers are impractical. The National Cyber Security Centre recommends external storage where internet access is unreliable; removable media should be stored securely and disconnected when not in use.
Scheduled backups, status monitoring and documented restore steps matter more as devices multiply. Synology describes central management and file or whole-device recovery in its Active Backup for Business documentation; check compatibility with the particular devices and NAS under consideration.
For laptops, email, invoicing and customer files, decide what must be recoverable and how soon work needs to resume before choosing where backup copies will live.
| Concern | What to check | Who this matters to |
|---|---|---|
| Restoring working data | Check which files and devices are protected, how often copies are made, and whether you need file-level or whole-device restoration. | If a failed laptop would stop invoicing or access to working files, I need to restore essential data and resume work. Around 33% of consumers put operational recovery first. |
| Recoverability and privacy | Check earlier-version restoration, protection against backup deletion, separate access controls and encryption key management. | If malware damages newer copies or a storage device is lost, I need recoverable files without exposing customer information. Roughly 25% of consumers prioritise this combination of recovery and privacy. |
| Connectivity and local copies | Compare the initial data size with the available upload window; check local capacity, encryption and secure storage for removable media. | When uploads cannot finish reliably, I need a local copy I can use without leaving a drive connected all day. About 25% of consumers put practical local recovery first. |
| Managing multiple devices | Confirm device compatibility, backup-status alerts, restore permissions and support for a separate destination. | With several laptops to protect, I need to spot missed backups and control who can restore files. Around 17% of consumers prioritise central oversight. |
The National Cyber Security Centre says previous versions and deleted-file features should not be the sole reliable backup for critical data.
Check how essential files can be exported and restored from an independent copy if the usual workspace or account is unavailable.
The National Cyber Security Centre warns that viruses can affect storage connected to an infected computer.
Disconnect the drive after backups, store it securely and keep another copy of operationally critical files.
A NAS at the workplace remains a local device. The National Cyber Security Centre recommends separate backup credentials and protection against destructive changes for on-premises backups.
Restrict management access and arrange an isolated or off-site copy rather than treating the NAS as the only recovery location.
Encryption can help protect stored personal information, but the Information Commissioner's Office also emphasises appropriate key management and staff processes.
Decide who can unlock and restore backups, protect recovery keys, and remove access when staff or suppliers leave.
Its Active Backup for Business software is relevant to teams considering centrally managed NAS backups for multiple devices.
Its NAS range is relevant where a business wants local storage with further backup destinations.
Its external drives are relevant when a removable local copy fits the business's backup routine.
No, not as the only protection for critical business data. The National Cyber Security Centre advises keeping an independent backup rather than relying solely on a cloud service's previous versions or deleted files; check that essential data can be exported and restored when the usual account is unavailable.
Consider encryption when backups contain personal information, particularly on storage that could be lost or stolen. The Information Commissioner's Office describes encryption as an appropriate measure depending on the processing risks; passwords, recovery keys and access controls still need managing.
A provider's location does not by itself rule out the service, but handling personal information may require further checks. The Information Commissioner's Office says UK restricted-transfer rules apply when their conditions are met, including making personal information accessible to a separate organisation outside the UK; check the applicable transfer mechanism and processor arrangements before choosing a provider.
Test whether essential files can actually be located and restored, not just whether a backup job reports success. Check cloud export and account access, removable-media readability, and—if using a NAS—restore permissions and access to an isolated or off-site copy.
