Choose automatic cloud backup if restoring to a replacement phone is the priority, or a computer backup if you have a computer and want a separate local route. Use external storage mainly for copies of selected photos and files, checking phone compatibility before relying on a direct connection. Apple Support and Google Help both distinguish backup and restoration from file-transfer workflows; neither a drive copy nor a cloud backup guarantees that every app’s data will be available.
These owners want important information ready to restore or transfer after a phone is lost, damaged or replaced. Apple Support describes iCloud and computer backup routes for iPhone; Google Help describes restoration to the original or some other Android phones.
These owners need room for photos, videos and files while deciding which originals to preserve separately. Google One Help distinguishes Original quality from Storage saver in Google Photos, making the quality setting relevant to storage planning.
These owners prefer to copy selected files to a computer or portable drive, including when cloud access is impractical. Direct phone-to-drive copying calls for checks on the phone, connection and file-access workflow; Apple Support sets additional format, partition and sometimes power conditions for iPhone-connected storage.
Choose a restoration method first, then decide whether important photos and files also need a separately maintained copy. A cable or adapter enables a compatible connection; it is not a backup destination.
Choose it when: You want a backup available for phone replacement without making each copy manually.
Allow for: Account access and cloud capacity, plus limits on which app data and settings can be restored. Apple Support says automatic iCloud Backup requires power, Wi-Fi and a locked screen.
Choose it when: You have a Mac or Windows PC and want a local backup route before changing phones.
Allow for: Computer storage and access to a recent backup. Apple Support says an iPhone computer backup must be encrypted to include Health and Activity data; keep its password safe.
Choose it when: You chiefly want a separate copy of selected media and files, made through a computer or directly from a compatible phone.
Allow for: Manual updates and connection checks. Apple Support describes iPhone external storage for file access, not as a substitute for its device-backup methods.
| Concern | What to check | Who this matters to |
|---|---|---|
| Restoration after loss or replacement | Check that the backup has completed and that its contents and restoration route suit your phone. For an iPhone computer backup, decide whether encryption is needed for Health and Activity data. | If my phone becomes unavailable, I need important information ready for the next one. Around 42% of consumers put restoration readiness first. |
| Media capacity and quality | Review available cloud space and photo-quality settings, then decide which originals also need a separate copy. | With a growing photo or video library, I want room for new files without losing the quality I need to retain. For around 33% of consumers, media capacity and preservation are the primary concern. |
| Separate local file copies | Check the intended phone or computer connection and file-access method. For an iPhone-connected drive, confirm its supported format, single data partition and power needs. | When I want important files somewhere I manage separately, I need a copying workflow I can repeat. Local or direct-copy control comes first for around 25% of consumers. |
Apple Support describes copying files with connected storage separately from its iCloud and computer device-backup methods. A folder of photos does not by itself establish that settings or app data can be restored.
Decide whether you need selected files, a restorable device backup or both. Open a sample of copied files and check the latest device-backup date before erasing or trading in a phone.
For iPhone, Apple Support specifies supported drive formats and one data partition; some external hard drives also need separate power or a powered hub. A matching plug does not settle those requirements.
Identify your exact phone and connector, then check the drive format, partition layout, adapter and power arrangement for the intended copy workflow.
Samsung UK says the stated maximum speeds for its T7 Shield depend on a compatible USB 3.2 Gen 2 host and cable with UASP enabled. Other connections may limit transfers.
If you regularly move large videos, check the computer port and cable alongside the drive specification; otherwise, prioritise a connection and copying routine you can use consistently.
Google One Help says Original-quality Google Photos uploads count towards account storage, while Storage saver can reduce the resolution of some photos and videos.
Review account space and the selected quality setting before backing up a large library. Keep a separate copy of selected originals if retaining their captured resolution matters to you.
Relevant to iPhone owners comparing iCloud, computer backups and direct access to external files.
Relevant to Android owners using Google Account backup, Google Photos and transfer during phone setup.
Relevant here for its T7 Shield portable SSD range as storage for a separately managed file copy.
Relevant for compact transfer media such as the DataTraveler microDuo 3C USB flash drive.
These Joybuy drives offer portable space for separately managed photos and files. Some are described for phone-connected use; others suit a computer-managed copy. Check your exact connection and file-access method, and keep a device-backup route if restoring settings and app data matters.

Consider it for selected-file copies if the intended iPhone 15/16, computer or other named device supports your connection and file-access workflow.
The title specifies USB 3.2 Gen 2 and up to 1,050 MB/s read and 1,000 MB/s write; those are rated speeds, not assured phone-transfer speeds. Confirm drive format and any mounting or power requirements before direct phone use.
No image available
For a separate media-file copy, check the intended phone model and precisely which files its supported apps can transfer; phone recording claims do not establish a restorable device backup.
The title lists USB 3.2 Gen 2x2, IP65 and up to 2,000 MB/s read and write. It names iPhone 15/16 Pro and Galaxy S25 recording uses; confirm the applicable model, connection and workflow rather than treating the rated speed as a phone result.

Consider this USB-C drive for a computer-managed copy of selected phone files. Check the computer connection, cable and drive format for your planned transfer.
The title specifies USB 3.2 Gen 2. For Samsung UK’s matching T7 Shield model, stated speeds of up to 1,050 MB/s read and 1,000 MB/s write require a compatible USB 3.2 Gen 2 host and cable with UASP enabled.

The 2TB capacity makes this an option for keeping a separately managed copy of a large selection of photos and files. Confirm the cable, computer or phone connection and drive format for your intended workflow.

The USB-A and USB-C connectors offer a way to move selected files between devices that support the drive and the intended file-access method. Check your exact phone and its supported drive format before relying on direct copying.
The title specifies USB 3.2 Gen 1 and a rated read speed of up to 570 MB/s; it does not establish a complete phone-backup method.
Cloud backup can be your main restoration route if it has completed and covers the information you need. Apple Support says an iCloud device backup excludes items already synchronised with iCloud, while Google Help warns that not all Android apps restore all settings and data. Check the backup and keep a separate copy of particularly important files where appropriate.
You can copy selected files to compatible connected storage through Files or supported apps, but do not equate that with an iPhone device backup. Apple Support says to check the connector or adapter, supported drive format, single data partition and any external power requirement.
Check that the backup has completed, which Google Account holds it and which transfer options the new phone supports. Google Help says restoration varies by phone and Android version; a backup from a higher Android version cannot be restored to a phone running a lower one.
Not necessarily: Google One Help says Storage saver can resize photos above 16 MP and videos above 1080p. If captured resolution matters, review the Original quality setting and your available account storage, or keep a separate local copy of selected originals.
