Choose a backup route according to what must come back: use your phone platform’s supported cloud or computer backup for restorable device data, and compatible removable storage for copies of selected files. A drive holding photos is not automatically a backup that can restore apps and settings. Before erasing the old phone, check what the backup includes, that you can access the account or computer needed to restore it, and that the copy is recent.
If you want the new phone to recover more than visible files, check its supported restoration method and account requirements before retiring the old one. Apple Support and Google Android Help document device-backup workflows separately from file copying.
Check how much space your media needs and whether you can open the copies afterwards. A removable copy can sit alongside a cloud backup; the UK National Cyber Security Centre advises checking that a backup contains your important data.
Confirm what your backup contains and how you will sign in and restore it before you erase the phone. Transfer arrangements intended for a qualifying new-device purchase may not apply to a reset.
Decide whether you need to restore the phone’s data or keep accessible copies of particular files, then check capacity and the connection or account needed for that route.
| Priority | What to check | Your needs |
|---|---|---|
| Recoverable data | Check which apps, settings, contacts and files the platform backup includes; identify content synced separately. Inspect the backup before erasing the phone. Apple Support and Google Android Help distinguish device backups from file access. | I want my new or reset phone to recover the data I rely on, not just display copied photos. |
| Space and duration | Compare the files or backup with available account or drive capacity. For a qualifying new iPhone or iPad transfer, check Apple’s temporary iCloud storage eligibility and restoration period; assess ongoing capacity separately. | If this is a one-time move, I want to check the space already available before taking out an ongoing subscription. |
| Connection and method | Check the exact phone, connector, drive format, power needs and app used to copy files. For a computer route, confirm the platform’s backup procedure rather than assuming a USB file transfer saves app data. | I need to know whether my phone can use the drive or card directly, or whether I will need a computer. |
| Access and protection | Keep access to the backup account and restoration credentials. Apple Support says Health, Activity and Keychain data require an encrypted iPhone computer backup; retain its password. Protect removable copies and disconnect them when not in use, as the UK National Cyber Security Centre advises. | After the old phone is gone, I still need to reach the backup without leaving a removable copy unnecessarily connected. |
Apple Support describes iPhone device backups separately from external-file access; copying Android files likewise does not establish that every app’s data and settings can be restored.
List what must return, then confirm the phone platform’s restoration method before choosing file storage.
A phone also needs to recognise the storage in the intended app. Apple’s external-storage guidance includes drive-format and power requirements.
Check the exact phone, connector, format, power arrangement and file-copy workflow.
That setup may call for a suitable adapter, card reader or powered connection.
Apple offers temporary iCloud storage under conditions for a qualifying new iPhone or iPad transfer, with a limited period to restore the backup. That does not answer whether you need capacity for future backups.
Check eligibility and existing storage first, then consider ongoing capacity as a separate decision.
Some content is backed up or synced separately, so a completed copy may not contain everything you intend to keep.
Check a recent backup, account access and inspectable files; where possible, complete the restore before erasing or disposing of the old phone.
The phone platform determines the restoration workflow; a storage brand does not, by itself, make copied files a restorable phone backup.
Apple Support documents iPhone backups through iCloud or a Mac or PC, as well as access to files on supported external storage.
Google Android Help documents account-based backup, while Files by Google covers file access on supported USB storage and SD cards.
Samsung UK documents Smart Switch transfer between Galaxy devices and computer-backup workflows.
Kingston identifies the DataTraveler microDuo 3C as a USB-C and USB-A flash-drive line for file transfer.
Crucial identifies the X9 1TB portable SSD, model CT1000X9SSD9, as a separate storage option.
These portable SSDs are options for keeping separate copies of selected phone files, directly where the phone supports the connection or through a computer. For apps and settings, use the phone platform’s supported restoration workflow as well.

Consider the 1TB capacity for a separate photo or video file copy. Check whether your phone or computer supports the USB Type-C connection and intended copying method; storing files here does not create a restorable backup of apps and settings.

The 2 TB capacity is worth comparing with a large collection of files you want to copy separately. This USB Type-C, USB 3.2 Gen 2 SSD stores files; confirm the connection and file workflow for your device, and use a supported phone backup for restorable app data and settings.

This 1TB USB 3.2 Gen 2x2 drive is a file-storage option for a phone workflow that supports external storage. If you plan to attach it to an iPhone or record video directly, confirm the exact phone and recording requirements first; it does not replace an iPhone device backup.

Use the 1TB capacity as a starting point for checking a separate file-copy or supported video-storage workflow. Its stated interface is USB 3.2 Gen 2x2; confirm host compatibility for the intended transfer, and keep a platform-supported backup if apps and settings must return.

Consider this USB 3.2 Gen 2 model for a separate 1TB file copy, after checking the exact phone connection and file app. The magnetic set does not make the drive a restorable backup for phone apps and settings.
Do not treat files copied to a USB drive as a restorable iPhone device backup. Apple Support documents iCloud and computer backups for restoration; its external-storage instructions describe accessing files through supported apps.
Files by Google documents USB access on Android 7.0 and later, and SD-card copying on Android 8.0 and later. The phone must support and recognise the storage; copying files does not establish that its apps and settings have been backed up.
Confirm a recent backup, inspect the files or contents you can check, and make sure you can access the account and restoration method. Check separately synced content and app-specific exclusions; where possible, restore the new device before erasing the old one.
Not necessarily: Apple Support says qualifying buyers of a new iPhone or iPad without enough iCloud backup space can obtain temporary storage for the transfer. Check eligibility and its restoration deadline, then decide separately whether future backups need more capacity.
Check the capacity you need after the phone change, along with renewal, cancellation and data-access terms. The UK Competition and Markets Authority identifies clear information about renewal and cancellation as important for cloud-storage providers.
