Who this guide is for

People keeping irreplaceable files

If you want family photos and important documents to remain recoverable after a lost, damaged or compromised device, distinguish a separate backup from synchronisation. The National Cyber Security Centre and Which? explain why keeping a recoverable copy matters.

People with a growing library

If photos and documents are filling your available space, measure the collection, allow for growth and compare local-drive capacity with cloud allowances. Apple, Google and Microsoft each describe storage limits for their services.

Households using several devices

If your files start on a phone, Windows PC or Mac, check which libraries and folders your chosen setup actually backs up. Apple and Microsoft describe different workflows for photos and computer files.

What to consider before choosing

Decide what you need to recover from, then choose a local drive, cloud storage or a maintained combination. A device or subscription only protects the files its backup setup actually includes.

Concern What to check when buying Who this matters to
Recovery after loss or deletion Check where each copy is stored, whether earlier versions can be restored and when the last backup completed. If my phone or computer is lost, I want a copy I can restore separately from the original. Around 26% of consumers put recovery after loss, deletion or corruption first.
Capacity for growth Measure the files and libraries to include, check existing cloud usage and allow for growth on each separate copy. I want enough room for the collection I have now and the files I expect to add. Around 21% of consumers put capacity first.
Coverage across devices List each device, operating system, photo app and document folder; confirm the backup covers them and check its completion status. If my photos and documents are spread across a phone and computer, I want the chosen setup to include the right files automatically. Around 21% of consumers put device coverage first.
Privacy and account access Review sharing settings, account-recovery options and whether the particular drive or software offers encryption. When my files are sensitive, I want control over who can access them without losing the ability to restore them. Around 16% of consumers put privacy and continued access first.
Ongoing cost Compare the capacity you need with current billing terms, and decide whether you also need an independent local or off-site copy. I want enough space without taking on a recurring charge I do not need. Around 16% of consumers put keeping ongoing costs manageable first.

Backup mistakes to avoid

  • Mistaking photo synchronisation for an independent backup

    Apple says that deleting a photo in iCloud Photos deletes it across devices where the service is enabled, and that those photos are not duplicated in iCloud device backup.

    Keep a separate copy of irreplaceable photos and practise restoring a file.

  • Leaving the only backup drive permanently connected

    The National Cyber Security Centre describes incidents in which connected USB and network backups were affected alongside the original files.

    Keep another copy and disconnect a local backup when it is not in use, while still updating it regularly.

  • Treating a free cloud allowance as space reserved for photos

    Google’s free account allowance is shared across Gmail, Drive and Photos; Apple’s iCloud allocation is also used by more than photos.

    Check actual account usage and expected growth before choosing a storage tier.

    As the collection grows, you may need to move to a paid tier sooner than expected.

  • Assuming a fast or rugged SSD guarantees file preservation

    Samsung qualifies the T7 Shield’s stated speeds by the host and cable, and its resistance ratings by test conditions; its cited warranty excludes liquid, dust and drop damage.

    Check whether the speed or resistance rating suits your use, and keep another recoverable copy.

Relevant brands to consider

Western Digital

The WD Elements Portable 2 TB is a capacity-led external HDD option for keeping a local copy of computer files.

  • Western Digital specifies USB 3.2 Gen 1/USB 3.0 connectivity for this variant.
  • Check the exact connector and your computer’s backup workflow; the interface specification does not establish the drive’s long-term durability.

Samsung

The T7 Shield 1 TB is a portable SSD option when carrying a local copy or transferring files is important.

  • Samsung specifies sequential speeds of up to 1,050/1,000 MB/s and IP65 resistance for the cited model, subject to host, cable and test conditions.
  • Samsung says liquid, dust and drop damage are excluded from its stated warranty; these ratings do not replace a separate backup.

Apple

iCloud Photos and iCloud+ are relevant to libraries in Apple’s Photos ecosystem; Time Machine is a separate Mac-to-drive option.

  • Apple lists 5 GB of free iCloud storage and paid iCloud+ plans.
  • Apple says iCloud Photos synchronises deletions and that those photos are not duplicated in iCloud device backup. Check your library and account quota before relying on the service as a backup.

Google

Google Photos, Drive and Google One provide photo and file storage linked to a Google Account.

  • Google says an account includes up to 15 GB of storage shared across Gmail, Drive and Photos; Google One can increase the total capacity.
  • The allowance is shared across those services, not provided separately for each one.

Microsoft

OneDrive and Windows backup tools are relevant to Windows folders; File History offers a separate external-drive workflow.

  • Microsoft describes 5 GB of free cloud storage, and File History can back up to a configured external or network destination.
  • Microsoft’s storage terms depend on the particular subscription and can change. Check the current plan terms rather than assuming an older allowance.

Frequently asked questions

How much storage should I plan for if I want two backups?

Measure the files you intend to protect and allow for growth on each separately stored destination. If you are backing up a whole Mac with Time Machine, Apple recommends a destination with at least twice the Mac’s storage capacity; check how much of any cloud allowance is already used by other services.

Will plugging in an external drive automatically back up my phone and computer?

No, the drive alone does not establish an automatic backup workflow. Windows File History and Mac Time Machine require configuration and a supported destination; check phone backup support separately for your specific phone, connector and app.

If iCloud Photos shows my pictures on another device, do I still need a separate backup?

Yes, if you want to guard against synchronised deletion. Apple says deletions in iCloud Photos propagate across devices using the service and that those photos are not duplicated in iCloud device backup; keep a separate copy of a library you need to recover.

What happens when a free cloud allowance fills up?

The effects depend on the provider. Apple says a full iCloud allocation prevents new iCloud Photos uploads and iCloud device backups, while Google’s allowance is shared across Gmail, Drive and Photos. Check your account’s actual usage before relying on automatic uploads.

What should I check before subscribing to cloud storage?

Check the plan’s capacity, recurring charge, sharing settings and account-recovery options, and how you would retrieve or export your files. The Information Commissioner’s Office notes that cloud files are held on servers controlled by the provider, so consider account access and the provider’s terms as part of your choice.
