Cloud backup can provide an account-based route to restoring data on a new phone or computer when you have reliable internet, enough account storage and access to your sign-in methods. For important photos and documents, add a separate local copy rather than relying on one device or account. The National Cyber Security Centre advises keeping removable backup storage disconnected when it is not in use; check device compatibility and open or restore files before erasing the old device.
Check how photos, documents, settings and required app data will reach the new device before erasing the old one. Apple Support and Microsoft Support describe backup and transfer routes for their respective devices, but the content restored depends on the method used.
A separate copy matters when the files cannot be recreated. The National Cyber Security Centre warns that ransomware can affect connected backup drives, so a removable copy should be stored separately after use.
An external drive or other removable storage offers a local file-copy route without depending on a cloud transfer. Check the ports, storage format and power requirements of the devices that will read it.
For a new-device move, establish how you will restore the data you need, then decide whether an additional disconnected file copy would reduce your reliance on that restore route.
| Priority | What to check | Your needs |
|---|---|---|
| Restoring to the new device | Confirm the restore method works with the replacement device and operating system. Check whether it transfers settings and app data or only files, and complete a restore check before erasing the old device. | I need more than a folder of photos if I also expect my settings or app data to move across. |
| Backup scope | Check photos, documents, settings and account-synchronised content separately. Apple Support distinguishes content synchronised to iCloud from content included in iCloud Backup. | Files visible on my old device must have a clear recovery route, even if they are not all held in one backup. |
| An independent copy | Keep an important file copy in a separate location. The National Cyber Security Centre warns that connected USB and network backup drives can be affected during ransomware incidents; disconnect removable storage after copying. | For photos and documents I cannot recreate, I want a copy that does not stay attached to the computer. |
| Device compatibility | Match the connector and any adapter to both devices. For phone storage, check the supported file format, partition and power requirements; direct USB storage on Android also depends on device support. | If I move files between a phone and computer, I need to know that each can actually read the storage. |
| Cloud account access | Check account storage, sign-in details, recovery methods and available version history before changing phones. The National Cyber Security Centre recommends 2-step verification for important accounts, including cloud storage. | I need access to my cloud copy during setup, including a way to sign in if the old phone receives my authentication codes. |
Apple Support distinguishes content already synchronised to iCloud from iCloud Backup. The restore method may therefore matter as much as the presence of files in an account.
Check how each important photo, document, setting and item of app data can be recovered before erasing the old device.
The National Cyber Security Centre reports ransomware incidents affecting connected USB and network backup storage.
After copying, safely eject the removable storage and keep it separately. Periodically open files or test a restore.
A connector that fits does not establish that a phone can read a drive. Apple Support specifies format and partition conditions for iPhone external storage, while direct USB use on Android requires device support.
Check both devices’ ports, supported formats and available power, along with any adapter or cable needed.
A cloud restore may require a sign-in method tied to the phone being replaced.
Confirm your password, recovery contact details and 2-step verification method, and keep the old phone available until the transfer or restore is complete.

For iPhone and iPad owners considering iCloud Backup, device transfer or access to removable files.
For Windows users considering an account-based move or local copies of documents.
The T7 Shield is a portable SSD example for transferring files between compatible devices.
Relevant to moving selected files using compact USB storage.
These external hard drives and portable SSDs are options for keeping a separate copy of photos and documents. Check how files will move between your particular devices; a file copy does not by itself restore every setting or app.

Consider this external hard drive for a separate local copy of a photo or document collection. It is the 5TB for Mac variant; check the setup required for your intended computer and confirm the applicable warranty terms before buying.
If you plan to use it with a phone or tablet, check connection, power and file-format compatibility separately.

This portable SSD is an option for carrying a separate copy of files between compatible devices. Its title specifies 1TB and USB 3.2 Gen 2; check the intended device’s connection and supported file format rather than assuming it will work directly with a phone.
A copy on this drive alone is not a complete device-settings or app restore.
No image available
Consider this USB 3.2 Gen 2 SSD for an additional file copy if its connection suits your devices. The magnetic set is described for iPhone 15/16 setups with the specified accessories; check the mounting arrangement and supported file format before transferring files.
The stated transfer speeds are maximum figures, not a promise for every host device.

The 2TB portable SSD is a local-copy option for a larger photo or video collection. Confirm its connector, supported file format and compatibility with the phone or computer you intend to use.
Keeping files on a separate drive does not itself create an automatic restore path for device settings or apps.

This external hard drive offers a 4TB local-copy option for photos and documents. Check the file-format requirements for your computer, particularly if you intend to use it with a Mac rather than its stated Windows setup.
For phone or tablet use, confirm the connection and power requirements before purchase.
Use a cloud restore route when you have reliable internet, sufficient account storage and a way to sign in during setup. Add a separate removable file copy for important photos and documents; the National Cyber Security Centre advises not leaving backup media connected when it is not in use. Check what each method can actually restore before erasing the old device.
No. Apple Support says iCloud Backup excludes content already synchronised to iCloud, and backup methods differ in what they include. Check the recovery route for your photos, documents and required app data before erasing or trading in the old iPhone.
Yes, with compatible storage and accessories. Apple Support specifies supported formats and a single data partition for external storage; you may also need an adapter, and an external hard drive may need additional power. Check the intended iPhone and storage setup before buying.
Yes. Microsoft Support says File History can make recurring copies to an external drive or network location and restore earlier file versions. Check that important folders are covered, adding folders outside the default libraries where needed.
No. Two-step verification helps protect account access; it does not create a copy of your files. The National Cyber Security Centre recommends enabling it for important accounts, including cloud storage. Keep your recovery methods available when changing phones.
