Who needs which back-up approach?

Households protecting irreplaceable memories

If losing family photos or important documents is the main worry, keep a usable local copy and another copy outside the home. Which? describes loss, theft, damage and malware as risks to files, while the Information Commissioner’s Office advises keeping important copies away from home.

People backing up across several devices

Automatic cloud back-up can reduce the need to remember a drive, but check which folders and photo libraries are included. Access on a replacement device also depends on the relevant account and service settings.

Households with large file libraries

Measure the photos, videos and documents to be protected before choosing drive capacity or a cloud plan. A large local copy still needs a separate off-site copy if a home incident is part of the risk you want to cover.

What matters when choosing back-up storage?

Decide how you would recover files after losing a device or access to your home, then size the storage and check that the chosen folders are actually backed up. A portable SSD, an external hard drive and cloud storage address different parts of that job; using a drive alongside cloud storage also means maintaining both copies.

Concern What to check Who this matters to
Off-site protection Confirm that important folders have uploaded to a cloud account or are copied to a drive stored elsewhere. Test a restore. If theft or damage at home could affect the computer and its nearby drive, I want another copy beyond the home. Around 31% of consumers put this off-site protection first.
Automatic back-up and recovery Check folder selection, account-recovery details, available storage and the service’s restore options. When files change across devices, I need back-up to run without connecting a drive each time and want to regain access after replacing a device. For around 31% of consumers, that automatic recovery is the primary need.
Capacity and ongoing cost Measure the library, allow room for growth and back-up history, and check whether household members share a cloud quota. With a growing photo and video library, I want enough space without committing to more cloud storage than I need. Capacity and ongoing cost come first for around 23% of consumers.
Portability and compatibility Match the drive’s connector, cable and file format to the intended devices; treat quoted maximum speeds as conditional. If I carry a local copy between computers or move large files regularly, the connection and ease of carrying matter most. Around 15% of consumers prioritise portable transfers.

Back-up mistakes to avoid

  • Assuming sync covers every file

    Only selected folders and successfully uploaded files are available through a cloud back-up. A synchronised deletion may also call for a restore feature or another independent copy; Microsoft OneDrive and Apple iCloud recovery options have conditions and limits.

    List the folders and device libraries you need, inspect their settings and restore a non-critical test file from each back-up route.

  • Choosing a drive by its advertised speed alone

    A portable SSD’s quoted maximum rate can depend on the computer’s port, the cable and protocol support. Samsung states these conditions for its T7 Shield transfer-rate claims.

    Check the intended computer’s connection and the supplied cables before deciding whether a speed claim is relevant to your use.

  • Keeping the only back-up beside the computer

    The same theft, fire or flood could affect both devices. The Information Commissioner’s Office identifies a copy outside the home as part of a back-up solution.

    Keep an additional copy off-site, whether through a suitably configured cloud service or a separate drive stored securely elsewhere.

  • Letting cloud storage fill up

    Google says a full account can prevent new Drive uploads and Google Photos back-ups, and affect Gmail sending and receiving. Several family members may use a shared storage quota.

    Check storage use regularly and leave enough room for new files and photos.

Relevant brands and services

Samsung

The T7 and T7 Shield portable SSD lines are relevant when a compact local copy will be carried between compatible devices.

  • Samsung lists T7 Shield capacities of 1 TB, 2 TB and 4 TB. Its stated maximum transfer rates depend on compatible USB 3.2 Gen 2 hardware, cable and UASP support.
  • Samsung’s IP65 and drop-resistance claims for the T7 Shield come from controlled testing; they do not make a single drive a substitute for an off-site copy.

Microsoft OneDrive

A cloud option for households using Windows Backup to copy selected folders and access them through a personal Microsoft account.

  • Microsoft says Windows Backup can select standard user folders for OneDrive back-up.
  • Check the selected folders and plan before relying on recovery: Microsoft says restoring an entire OneDrive to an earlier point requires Microsoft 365, and permanently deleted recycle-bin files cannot be recovered.

Apple iCloud+

Relevant to Apple-centred households using iCloud Photos, iCloud Drive and iPhone or iPad back-up.

  • Apple offers iCloud+ storage tiers and family sharing for up to five other family members.
  • Apple advises making an additional archive or copy of iCloud information. Its file-recovery window has limits, so check recovery options before relying on synchronisation alone.

Google One and Google Photos

Relevant to households using Google accounts for automatic photo back-up and storage across Photos, Drive and Gmail.

  • Google says family-group members can share storage without automatically sharing their files; invited members must live in the same country.
  • Photo back-up needs an internet connection, and a full shared quota can stop new uploads. Check account access and storage headroom.

External drives for local back-ups

These portable hard drives and SSDs can provide the local-copy part of a household back-up plan. Choose capacity against the files and back-up history you intend to keep; add a separate off-site copy if you also need protection against a loss affecting your home.

Common questions

How large should an external back-up drive be?

Choose a drive that holds the files you plan to protect, with room for growth and back-up history. For a Mac using Time Machine, Apple recommends a disk with at least twice the Mac’s storage capacity; that is Time Machine guidance, not a sizing rule for every back-up method.

Can cloud sync replace an external back-up drive?

Cloud sync can provide an off-site copy, but do not assume it independently preserves every file or deletion. Check which folders have uploaded and what recovery options apply; Apple advises making an additional archive or copy of information stored in iCloud.

What does Windows Backup copy to OneDrive?

On consumer Windows 10 and Windows 11 devices using a personal Microsoft account, Windows Backup can copy selected standard folders to OneDrive. Microsoft names Desktop, Documents, Pictures, Videos and Music; check the selection and available storage rather than assuming files elsewhere are included.

What should I check before relying on a cloud account for recovery?

Make sure you can regain access to the account as well as the files. Use a unique strong password, enable multi-factor authentication where available, keep recovery details current and check the service’s storage and restore conditions. The Information Commissioner’s Office recommends strong, unique passwords for important cloud-stored files.

Is a cloud-storage subscription an ongoing commitment?

A paid cloud plan involves a recurring charge while you keep that plan. Before choosing one, compare the storage your household uses with the plan’s quota, check sharing arrangements and review the current renewal terms.
