Who needs which kind of backup?

Households protecting family photos

If photos and videos on phones or computers would be difficult to replace, check that your storage has room for the collection and that another copy will remain available if devices at home are lost.

Students and people using several devices

If coursework or documents move between a laptop, phone and tablet, access away from home matters. Check which files remain available offline and how to recover an accidental deletion.

Self-employed workers keeping records

Work files and business records need a recovery plan as well as secure account access. If the files include client personal data, consider the relevant data-protection responsibilities before choosing a provider.

What matters when choosing backup storage?

Decide first whether you need rapid local recovery, access across devices, or both. Then check whether the arrangement protects a separate copy when a drive fails, an account is compromised or a file is deleted.

External backup drive

Choose it when: You need a local copy or cannot depend on broadband for a large upload; the National Cyber Security Centre recommends external storage where internet access is unreliable.

Keep in mind: A drive kept beside the computer is vulnerable to the same local incident, and one left connected may be affected by malware.

Network-attached storage

Choose it when: Several household or home-office devices need a shared local place for files and backups.

Keep in mind: A NAS needs compatible drives, configuration and maintenance; one in your home is not an off-site copy.

Cloud backup

Choose it when: An automatic copy away from home matters more than restoring directly from a local drive, and your connection can handle uploads.

Keep in mind: Check which computers, attached drives and files are covered, and how a full restore works.

Cloud file sync

Choose it when: You need current coursework or work files on several devices, including when away from home.

Keep in mind: Edits and deletions can spread between devices, so check recovery options and keep an independent backup.

Local and cloud copies

Choose it when: You need both a local restore route and a copy away from home for photos, coursework or work files you cannot recreate.

Keep in mind: Both copies need to complete reliably, and you must be able to restore from each.

Concern What to check Who this matters to
Independent recovery Check for a separate off-site copy, a local copy that can be disconnected, and a workable restore procedure. If losing a computer or its connected drive could take my only copy with it, I need another way to recover the files. Around 33% of consumers would put independent recovery first.
Access across devices Check supported devices, included folders, offline-file settings and deleted-file recovery. Coursework or work files need to be available when I switch devices or leave home. For around 27% of consumers, that access would be the primary concern.
Capacity and photo quality Measure the library and allow for growth; check shared account storage and the selected photo-upload quality. If my photo and video collection is growing, I want room for it without unintentionally changing the quality of files I intend to keep. Preserving that collection would come first for around 20% of consumers.
Security and records Check account recovery, two-step verification and sharing controls; assess provider terms if storing client personal data. When my backup contains work records or client information, I need to control access and retain what my business requires. Around 20% of consumers would make those responsibilities their main priority.

Backup mistakes to avoid

  • Treating one connected drive as the whole plan

    The National Cyber Security Centre warns that a connected backup can be affected by the same incident as the computer. A drive kept at home also cannot protect against the loss of everything stored there.

    Keep another copy away from home, disconnect a local backup drive when it is not in use, and try restoring a file rather than relying only on a completed-backup message.

  • Assuming a sync folder keeps an independent history

    A deletion or unwanted edit may sync to other devices. Microsoft provides OneDrive recovery features, but its stated deleted-file window for personal accounts is limited.

    Check the service's version and deleted-file rules, then use a separate backup destination for files you cannot recreate.

  • Choosing capacity without checking what shares it

    Google says Drive, Gmail, WhatsApp backups and Photos can share account storage. When an account is full, new uploads and photo backups can stop.

    Add up existing files and device backups, allow for a growing photo library, and check whether your chosen upload setting preserves the quality you need.

  • Overlooking account access and client-data duties

    A cloud copy is difficult to use if you lose account access. Where a self-employed person acts as a controller and a provider processes client personal data, Information Commissioner's Office guidance says the arrangement needs an appropriate written contract.

    Use a unique password and two-step verification where available, secure recovery details, review sharing permissions and assess provider terms before uploading client data.

Relevant brands and services

Apple

iCloud and iCloud+ are relevant when iPhone or iPad backup and access across Apple devices are central to your plan.

  • Apple says iCloud Photos syncs photos and videos separately when it is enabled; they are not then included in iCloud Backup in the same way.
  • Check which computer folders and family members your arrangement covers before treating the account as a complete backup.

Google

Google Photos, Drive and Google One are relevant to households already using Google accounts across phones and computers.

  • Google supports photo uploads and access to stored files from signed-in devices.
  • Google says account storage is shared across services. Its Photos Storage saver setting may resize photos above 16 MP and videos above 1080p; check the upload setting if originals matter.

Microsoft

OneDrive is relevant to Windows and Microsoft 365 users who want selected working folders available across devices.

  • Microsoft's Files On-Demand allows online-only files and lets users retain selected files offline.
  • Online-only files need an internet connection. Synced deletions require recovery through the applicable version or recycle-bin features rather than a separate backup copy.

Synology

Synology NAS devices, including its two-bay DS225+, are relevant when several devices need a central local destination.

  • Synology describes file, photo and device-backup functions for the DS225+.
  • Choose compatible drives and plan a separate off-site copy; a NAS in the same building does not provide one.

Backblaze

Backblaze Personal Backup is relevant to people seeking automated computer backup rather than a folder-sync service.

  • Backblaze says Personal Backup covers user-generated data on computers and connected external drives, with Mac and Windows clients.
  • Check device eligibility, what remains covered when an external drive is disconnected, and the current restore terms before relying on it.

External drives for a local copy

These portable drives can provide the local-storage part of a backup plan for photos or work files. Choose capacity against your actual collection, decide how files will be copied and restored, and keep a separate copy away from home for protection against a local loss.

Backup storage questions

Is cloud file sync the same as a backup?

No: sync keeps current files available across devices, but unwanted changes and deletions can spread too. Microsoft says deleted files in personal OneDrive accounts can generally be restored within 30 days; check the applicable recovery features and keep an independent copy of files you cannot replace.

What if my broadband is unreliable?

Use an external drive or NAS for a local backup rather than depending on every upload completing over an unreliable connection. The National Cyber Security Centre recommends external storage in this situation; disconnect a backup drive when it is not in use and arrange a copy away from home as well.

How much storage do I need for photos and files?

Measure the files and device backups you intend to protect, then leave room for the collection to grow. If you use a Google account, include the storage shared by Drive, Gmail, WhatsApp backups and Photos, and check the photo-upload quality setting before choosing a capacity.

How should I secure a cloud backup account?

Use a unique password and enable two-step verification where available, as the National Cyber Security Centre recommends. Review account-recovery methods and sharing permissions before relying on that account to retrieve your files.

What should a self-employed person check before backing up client files?

If you act as a controller and a cloud provider processes client personal data for you, Information Commissioner's Office guidance requires an appropriate written contract or other legal act covering the processing. Separately, GOV.UK says self-employed people must keep relevant business records for at least five years after the 31 January submission deadline for the relevant tax year; choose a backup arrangement that lets you retain and recover those records.
