Who needs which backup approach?

People protecting irreplaceable records

If losing financial documents, identity records or family photos would cause significant disruption, prioritise a copy kept apart from your main device and a restore process you can complete.

People backing up several devices

If files change on a computer, phone or tablet, look at which devices a cloud service can back up automatically. Check its storage allowance, account protection and options for restoring earlier files.

People with large photo and video collections

A portable drive can hold a local archive, but its capacity must cover the files you intend to copy. Plan when to update it, where to store it between backups and how to test a restore.

What should you check before choosing?

Start with how you will keep a recoverable copy separate from the original device, then decide whether automatic updates or local capacity matter more. A USB flash drive can hold a limited removable copy if it has enough capacity, but it still needs separate storage and a restore check.

Portable hard drive

Consider it when: You want substantial local space for documents, photos or videos and can update the drive on a regular schedule.

Trade-off: The drive needs protection from loss or damage and does not become a separately stored copy unless you put it away from the main device.

Portable SSD

Consider it when: You transfer files frequently between compatible devices and value a compact removable drive.

Trade-off: Transfer speed depends on the device connection, and the SSD still needs a separate storage location between backups.

Cloud service

Consider it when: You need supported files from several devices copied frequently without connecting a drive each time.

Trade-off: Restoring files depends on account access, the service’s recovery features and enough available storage.

Cloud and removable drive

Consider it when: Losing personal records or irreplaceable photos would be particularly disruptive and you can maintain two copies.

Trade-off: You must keep both copies current, store the drive separately and retain a way to recover the cloud account.

Concern What to check Who this matters to
Recoverability Can you keep a copy apart from the main device and restore a representative folder from it? If my computer is lost or its files are damaged, I need my records to be recoverable from another location; around 36% of consumers put that separation and restore need first.
Automatic copying Which devices and folders are covered, and what happens to uploads when the cloud allowance fills? Files change on my phone and computer, so I want recent copies without remembering to connect a drive; roughly 29% of consumers prioritise automatic multi-device copying.
Local capacity Measure the files to be copied, allow room for growth and check that your devices can use the drive. My photo and video collection keeps growing, and I need a local copy with room for it; around 21% of consumers place archive capacity first.
Account protection Check sign-in protection, encryption options and how you would regain access without your usual device. I want sensitive documents protected without losing my own way back into the account; about 14% of consumers make secure, recoverable access their primary concern.

Backup mistakes to avoid

  • Leaving the backup drive permanently connected

    A drive attached to the main computer can remain exposed to the same incident. The National Cyber Security Centre advises against a permanently connected backup device in its small-business guidance; for personal files, the practical question is whether your copy will remain separate when you need it.

    Copy the files, test a restore, then disconnect and store the drive separately when practical.

  • Overlooking a shared cloud-storage allowance

    Google says a full shared-storage account can prevent new Drive uploads and photo or video backups. A routine that previously worked may therefore stop protecting recent files.

    Check current usage, which services share the allowance and whether there is room for the files you expect to add.

  • Enabling stronger encryption without planning recovery

    Apple says it cannot recover the relevant encryption keys for iCloud data protected by Advanced Data Protection. Losing the available recovery route could leave you unable to regain access.

    Arrange and safely record a supported recovery method before relying on that protection for essential files.

  • Expecting an SSD’s rated speed on every connection

    Samsung notes that T7 transfer performance depends on the host configuration. A rated maximum does not describe the speed you will necessarily see when copying a backup.

    Check the drive’s interface against your device’s port and cable before treating its rated speed as a reason to choose it.

A cloud route to consider when backing up files within an Apple-device setup.

  • Apple describes optional Advanced Data Protection as adding end-to-end encryption for a majority of iCloud data categories.
  • With Advanced Data Protection, Apple cannot recover the relevant encryption keys for you; arrange a recovery contact or recovery key before relying on it.

Questions about backing up personal files

Is cloud synchronisation alone enough for important records?

Do not rely on synchronisation alone without checking how the service restores changed or deleted files. For records whose loss would be highly disruptive, keep another recoverable copy: the National Cyber Security Centre identifies both cloud storage and removable media as backup locations, while Microsoft Support describes defined recovery windows for OneDrive features.

Should I leave an external backup drive connected?

Disconnect and store a drive separately when you are using it as a removable backup and it is not being updated. That reduces its exposure alongside the main device; the National Cyber Security Centre gives similar advice for backup devices in its small-business security guidance, not as a legal rule for personal users.

What should I check before storing financial documents in the cloud?

Check the account’s two-step or two-factor authentication and make sure you can recover access if your usual phone is unavailable. Keep any supported recovery contact, key or backup codes somewhere safe and accessible without relying on the device you are backing up.

Does stronger iCloud encryption remove the need for account recovery?

No. Apple says it cannot recover the relevant encryption keys for data protected by Advanced Data Protection, so arrange a supported recovery contact or recovery key before enabling it for files you need to retain.
