Choose cloud storage if automatic backup and access from a replacement device matter most, provided you can keep access to the account and have enough storage and internet connectivity. An external drive suits a large collection you want to copy locally, while a USB flash drive is more suited to a selected set of files. For irreplaceable photos and documents, keep another copy in a separate location rather than relying on either device or account alone.
If photos, contacts, documents and settings need to move to a replacement phone or computer, check what the relevant account actually backs up. Apple, Google and Microsoft describe account-based backup or restore routes, but coverage depends on the device, app and enabled settings.
A removable drive can make sense for a substantial photo, video or document collection, particularly when uploading it would be impractical. Microsoft identifies external storage as an option for large numbers of files or when internet access is unavailable.
Think about both sides of a loss: whether someone else could open a misplaced drive and whether you could regain access to a cloud account. The Information Commissioner's Office discusses encryption as protection for stored information, while Apple provides account recovery options that are worth arranging in advance.
Start with the files you need to recover and the device you will restore them to. Cloud storage can reduce manual copying; a drive gives you a local copy, but you must keep it current and store it safely. A smaller flash drive is an option for selected files, not a substitute for checking the size of the whole collection.
| Concern | What to check | Who this matters to |
|---|---|---|
| Restoring a replacement device | Check the enabled backup categories, the last completed backup and whether the replacement device can use the same account. Google notes that Android restore coverage varies by phone and version. | If my phone is lost or reset, I want my essential files and supported device data available without relying on the old device. Around 33% of consumers may put restoring access first. |
| Large collections and capacity | Compare the size of the files you intend to copy with the storage capacity, leaving room for additions. Check the connection you will use to copy and restore them. | With a substantial photo or video collection, I need a practical way to make a complete copy when uploads are difficult. For around 27% of consumers, capacity and transfer practicality may be the primary concern. |
| Household sharing and privacy | Check who can join a shared plan, whose quota is used and whether each person keeps a separate account and private files. | If several people use one storage plan, I want each person to reach their own files without opening everyone else's. Around 20% of consumers may prioritise those sharing boundaries. |
| Local access and a separate copy | Check how a removable copy will be secured and stored, and set up cloud-account recovery if you use an online copy. Test access to essential files from the second location. | When a connection or account is unavailable, I still want a copy I can reach; I also do not want one incident to affect every copy. That may be the main concern for around 20% of consumers. |
Backup coverage can be selective. Google says not all Android apps can back up or restore every setting and item of data, so a completed backup does not by itself confirm that every essential file is recoverable.
Before wiping or replacing a device, inspect the selected categories and last backup, then open a sample of important files from another device or restore location.
The same theft, fire or flood could affect both. The Information Commissioner's Office notes that a cloud copy can remain available when an incident at home affects local equipment.
Keep another copy of irreplaceable material in a genuinely separate location and check that you can access it.
A drive's connector must work with the devices used to make and restore the copy. Samsung also says the host and cable affect whether its stated portable-SSD speeds can be reached.
Check the ports on both the current and likely replacement devices, as well as the drive's cable and intended file-transfer method.
An adapter, different cable or another compatible computer may be needed to move the files.
Losing a phone can also remove a familiar way to sign in. Apple says its account recovery process may take several days or longer.
Review recovery options while trusted devices and phone numbers are still available. If eligible, set up a recovery contact and keep a separate copy of essential documents.
iCloud and iCloud+ are relevant when an Apple-device household wants account-based backup and access on a replacement device.
Google Account backup, Google Photos and Google One are relevant to Android backup and households considering shared cloud capacity.
OneDrive and Windows Backup are relevant when files and supported PC settings need to be available after signing in on another Windows computer.
Samsung portable SSDs are relevant to local copies when the intended devices support the model's connection.
Kingston DataTraveler flash drives are relevant to portable copies of selected files when the connector suits the devices involved.
These drives and flash storage provide ways to make local copies of selected photos, documents or larger collections. Choose by the size of your files and the connections available for both backup and restore; keep a separate copy of irreplaceable material.

The listed 4 TB capacity makes this a local-copy option for a collection that needs more space. Check the required connection and file-system setup on the computers that will make and restore the backup.

This is another 1 TB local-copy option for files that fit within that capacity. The listed interface is USB Type-C, USB 3.2 Gen 2; confirm device compatibility and how you will keep the copy up to date.

A portable-copy option for a selected file set that fits within 512 GB. The title lists USB 3.2 Gen 1 and Type-C connections; check the ports and file-transfer method on each device you intend to use.
Use cloud storage if automatic backup and access after signing in are your priorities; choose an external drive if you need a local copy of a large collection or cannot depend on internet access. Microsoft identifies external storage as an option for large files or unavailable internet. Whichever route you choose, check that the files you need can be restored.
No cloud backup should be assumed to restore everything. Google says Android restoration varies by phone and version and that not all apps can back up or restore all settings and data. Review the enabled categories and test access to essential files before resetting a device.
Apple says people sharing iCloud+ can keep separate Apple Accounts and private files, while Google says Google One family members share a storage quota without automatically gaining access to one another's files. Check the chosen plan's membership and sharing settings before relying on it for the household.
Arrange another way to recover the account before the device is lost. Apple says an eligible recovery contact can help with Apple Account access, while its account recovery process may take several days or longer. Keep essential recovery information and a separate copy of critical files accessible without the lost device.
