Choose your phone or computer’s cloud-backup route if restoring through the same account ecosystem is your priority, but check which files, settings and apps it actually covers. Choose external storage for a separate local copy, provided you arrange the copying and can restore the files. For photos and documents that would be difficult to replace, using both routes reduces reliance on one account or storage location, although each copy still needs maintaining.
The useful distinction is what you need to recover: a working replacement device, particular files, or a second route to irreplaceable material.
If a phone or PC is lost, damaged or replaced, you want files and supported settings available through the account ecosystem you already use. Apple, Google and Microsoft each document backup and restore routes, but their coverage differs.
If you have photos, videos or computer folders to copy, a physical drive gives you another storage location. The National Cyber Security Centre advises keeping a backup separate from the original data; you still need to select the files and check that you can restore them.
If losing particular photos or documents would be especially disruptive, you may be willing to maintain both an account-based copy and a separately stored local copy. Check the contents of each rather than assuming the two routes protect identical files.
Decide whether your priority is restoring a replacement device or recovering selected files. Then check what the chosen service or storage device will actually copy, and practise retrieving a file before you need it.
Consider it when: You want a route for restoring supported data through your existing Apple, Google or personal Microsoft account.
Accept the limit: Account access, available storage, included data and the replacement device all affect what you can restore.
Consider it when: You want a separately stored copy of computer folders or a substantial collection of personal files.
Accept the work: A drive provides storage; you must set up copying or backup software and keep the resulting copy usable.
Consider it when: You intend to keep a deliberately selected set of essential files on removable media.
Accept the limit: It will not capture files you never copy or provide an assumed full-device restore.
Consider it when: Important files merit both an account-based route and a separately stored copy.
Accept the work: You must maintain account access and storage as well as the local copying and restore routine.
| Concern | What to check | Who this matters to |
|---|---|---|
| Replacement-device restore | Confirm the account and operating system, the last successful backup and whether the replacement device can restore the data you need. | If I replace my phone or PC, I want supported files and settings ready through an account I can access. Around 33% of consumers put replacement-device restoration first. |
| Recovery after deletion or damage to files | Check whether older or deleted versions can be retrieved and whether an independently stored copy covers your important files. | An unwanted deletion or change could reach my current files, so I need a way back to an earlier copy; for around 25% of consumers, that recovery need comes first. |
| A separate local copy | Check capacity, connectors and device compatibility, then confirm which folders the copying routine includes. | My photo, video or computer-file collection needs a physical copy I can keep away from the main device. That local-copy need is the priority for around 25% of consumers. |
| Selected-file simplicity | List the files to copy and check the removable device’s connector, capacity and any protection needed for sensitive files. | I only need to put chosen documents or photos somewhere separate, without assuming I can rebuild the whole device. Around 17% of consumers primarily want that selected-file approach. |
Apple says iCloud Photos synchronises separately from the daily iCloud Backup. Other data or unsupported apps may therefore need a different restore route.
Make a list of the photos, files, messages, app data and settings you would need after replacement. Check each category in your provider’s backup details and try restoring a non-critical item where practical.
Drive capacity and transfer speed do not show which folders have been copied. Microsoft’s File History can make recurring copies of included folders to an external drive, but it must be configured.
Choose the folders deliberately, set up a suitable copying routine and test retrieving a non-critical file from the drive.
SanDisk distinguishes software-encrypted vaults from hardware drive locking and says its hardware-encryption drive locking is not supported on USB flash drives or memory cards. Supported functions also depend on the device and operating system.
Check the exact model and host device, how password protection works, and how you would retain any recovery information before storing sensitive files.
Samsung says the stated maximum speeds for its Portable SSD T7 require a USB 3.2 Gen 2 host, a supporting cable and UASP mode.
Check your computer’s port and the connection you will use. Give backup coverage, compatibility and the restore process equal attention before choosing a drive.
These names represent different account-based backup services and local-storage product lines, not interchangeable ways to restore an entire device.
iCloud Backup is a route for restoring supported iPhone or iPad information after replacement, loss or damage.
Google Account backup provides an account-based restore route for supported Android data.
Windows Backup and OneDrive can help personal-account users carry selected files and settings to another Windows PC.
Samsung portable SSDs are local-storage options for a separately maintained file copy.
SanDisk portable SSDs and USB products offer local-storage choices whose protection features need model-specific checking.
These external drives and USB flash drive suit the local-copy side of the decision: choose according to the files you plan to copy and the devices you will connect. None replaces checking what your backup routine includes or testing a restore.

Consider this 2TB external hard drive for a separate copy of personal files. Decide which folders to back up, arrange a repeatable copying routine and check that you can restore a file on the computer you intend to use.
No image available
Consider this 1 TB USB Type-C SSD for a separate file copy. Check the connection and file access on your intended device, then set up copying rather than assuming that connecting the drive starts a backup.
No image available
Consider this 5TB Mac-oriented drive for a substantial local file copy. If you plan to use it with another computer too, check the file-system workflow before relying on the same copy for restoration.

Consider this 1 TB SSD when you want to keep a portable local copy. Confirm the connection and file-system requirements of each device you will use, and arrange a copying routine with a restore check.

Consider this 512GB dual-connector drive for a selected set of files rather than a full-device backup. Check file access on the phone, tablet or computer you intend to use, and confirm the protection method if the files are sensitive.
No: synchronised content and a device backup can cover different things. Apple says that, when iCloud Photos is enabled, photos and videos synchronise to iCloud rather than being included in the daily iCloud Backup. Check which files are synchronised, which are backed up and what you could restore to a replacement device.
No. Google says restoration varies by phone and Android version; a backup from a higher Android version cannot be restored to a phone running a lower version. Not all apps back up or restore every setting and item, so check the data you particularly need before changing phones.
Microsoft documents BitLocker Drive Encryption for Windows Pro, Enterprise and Education editions with administrator access, including BitLocker To Go for removable drives. Windows Home does not offer that BitLocker management route. Keep the recovery key separately: Microsoft says it cannot retrieve or recreate a lost key.
No. Apple states that UK users who have not already enabled Advanced Data Protection can no longer turn it on, and names iCloud Backup among the categories that cannot newly receive that protection in the UK. Check your existing account settings rather than assuming the option is available.
