Who this guide is for

People replacing a device

If you are moving to another phone or computer, check which photos, documents, settings and app data will actually restore—not just which files appear in a storage account. The National Cyber Security Centre advises people to back up important data, including when they have a new device.

People with growing photo libraries

If you want to keep an expanding collection of photos, videos and documents, consider both usable capacity and whether you can carry out the restore yourself. Apple Support and Microsoft Support describe backup options for Mac and Windows files respectively.

People seeking an independent copy

If you want another copy less exposed to the original device or sync account, consider how and where it is stored, and whether it is disconnected between backup sessions. The National Cyber Security Centre advises keeping an offline backup digitally disconnected when it is not in use.

What to prioritise when choosing a backup

Concern What to check when buying Who this matters to
Restoring the right data Check selected data categories and folders, replacement-device compatibility, backup completion and a sample restore. If I am changing devices, I want the files and device information I rely on to return, not just a list of uploaded files. Consumers who prioritise restore completeness account for around 25%.
Independent protection Check deletion behaviour and recovery periods, and whether another copy is disconnected and stored separately. If a device is lost or files are deleted, I want another copy that is not exposed to the same account or incident. Consumers who put independent protection first account for around 25%.
Capacity and ongoing commitment Measure the files to keep, include other use of shared cloud storage and allow for additions or retained versions. When my photo and document collection grows, I want enough usable space without overlooking other storage needs or an ongoing subscription. Consumers who prioritise capacity and cost account for around 25%.
Compatibility and upkeep Check connectors, readers or power needs, supported file systems, largest individual file, backup scheduling and restore steps. If I use removable storage, I want it to connect to my devices and fit a routine I can keep up with. Consumers who prioritise practical compatibility and maintenance account for around 25%.

Backup buying pitfalls to avoid

  • Counting a synced photo library as a separate historical copy

    With iCloud Photos enabled, deleting a photo also deletes it from devices using that sync. Apple Support explains that iCloud Photos content is not also included in the daily iCloud device backup.

    Check how deletion and recovery work for your service. If you need an independent copy, keep another copy through a separately maintained backup process.

  • Calling a file move a backup when only one copy remains

    Moving files off a device can leave you with just one surviving copy, rather than a separate backup.

    Before deleting anything, check what copies remain and whether you can open the files from the backup.

    Keeping another copy may require additional storage.

  • Buying removable storage by connector or total capacity alone

    A suitable connection and file system matter, and FAT32 cannot store an individual file of 4 GiB or larger. Apple Support also notes that external hard drives often need additional power with iPhone.

    Check the whole connection path and the largest file you plan to copy. Test copying and reopening files on the devices you intend to use.

    A reader, adapter or additional power supply may be needed for your setup.

  • Treating a rugged drive or warranty as protection for your files

    Samsung says the T7 Shield IP65 rating is based on controlled internal testing and that liquid and dust damage are excluded from its warranty. A drive’s physical characteristics do not show whether its data can be restored.

    Check the exact model’s warranty terms and keep another tested copy of important files.

    Damage outside warranty terms may leave you needing a replacement drive.

Relevant brands to consider

Apple

Apple offers distinct iCloud options for device backups and photo syncing, as well as Time Machine for Mac files.

  • Apple Support explains that Time Machine can back up files including apps, photos and documents.
  • iCloud Photos content is not also included in the daily iCloud device backup, and synced deletions can affect enabled devices.

Google

Google Account and Google One backup options are relevant to Android users and shared cloud-storage planning.

  • Google Android Help describes automatic device backups with selectable categories.
  • Restore compatibility varies by Android version and app. Google One Help says account storage is shared across Gmail, Drive and Photos.

Microsoft

OneDrive recovery and Windows File History provide distinct account-based and external-drive workflows.

  • Microsoft Support documents File History for library files and a 30-day recovery period for eligible personal OneDrive deletions.
  • Check which folders File History covers; it should not be treated as a complete disk-image backup.

Samsung

The T7 Shield 1 TB, model MU-PE1T0S/EU, is a portable SSD option for a separately maintained local copy.

  • Samsung UK describes an IP65 rating for this model based on controlled internal testing.
  • Samsung excludes liquid and dust damage from the warranty; a resistance rating does not establish that stored files are recoverable.

Kingston

Kingston DataTraveler removable storage is relevant to defined file-copy workflows.

  • Kingston Technology’s DataTraveler G4 support guidance covers file-system choices and usable capacity.
  • FAT32 cannot store a single file of 4 GiB or larger; check the specific device and file-system compatibility.

Seagate

Seagate’s Backup Plus Portable line has documented Toolkit support for backing up computer files.

  • Seagate UK identifies Toolkit support for the Backup Plus Portable line.
  • A backup workflow still needs to be configured, maintained and tested; the product-line name alone does not preserve files.

Frequently asked questions

What should I check before wiping or trading in my old device?

Check which data categories and folders are included, confirm the backup has completed and practise restoring representative files. Google Android Help notes that a backup from a higher Android version cannot be restored to a phone running a lower version, and not every app restores all its data.

How do I size a backup without guessing from the number of photos?

Measure the files you intend to preserve using consistent units, then account for other use of the same storage allowance and any versions you retain. Google storage is shared across services. For Time Machine specifically, Apple Support ideally recommends a disk with at least twice the Mac’s storage capacity, while noting that a smaller disk may still work and older backups are removed as space runs low.

Why will a large video not copy to a USB drive with plenty of free space?

A FAT32-formatted drive cannot store an individual file of 4 GiB or larger. Use a file system supported by both the source and restore devices; formatting erases existing data, so preserve anything you need before reformatting.

Does unplugging a drive make me ransomware-proof?

No; unplugging a drive does not guarantee protection. The National Cyber Security Centre recommends keeping a backup offline and not connecting every copy at once, because connected USB, network and cloud locations have been affected in ransomware incidents. Maintain the copy and test restoring from it; being disconnected does not verify its contents.

Will exported photos open on my replacement device?

Check the file formats and test them in the destination apps before relying on an export. Apple Support documents HEIF and HEVC support on iOS 11 and later and macOS High Sierra 10.13 and later, with limitations on some older devices. The Most Compatible camera setting creates new photos and videos as JPEG and H.264; it does not mean existing files have been converted.
