Choose a cloud route if automatic backup and access across devices matter most; choose a computer backup or external drive when you want a separately controlled local copy. These routes can work together, but they protect different content: check what your phone and computer actually back up, how much storage is available and whether you can restore the files you need.
If photos and documents are spread across a phone and computer, work out which files are synced, which are included in a device backup and which need a separate copy. Apple Support, Google Android Help and Microsoft Support describe different backup routes for their respective devices and accounts.
An external drive can hold computer files outside a cloud account. For an iPhone or iPad backup stored on a computer, Apple Support says encryption must be switched on separately if you want an encrypted local backup; keep its password somewhere you can retrieve it.
When photos, videos or projects are copied frequently, capacity, connections and portability affect the choice of drive. Compare the exact model and your devices’ ports rather than treating a quoted transfer speed as a result every connection will deliver.
Decide what must be recoverable after a device is lost or replaced, then choose where the copy will live. A USB drive used only for selected transfers does not take the place of a phone or computer backup.
Consider it when: You want a supported phone backup or selected computer files accessible through your account.
Trade-off: Recovery depends on account access and available storage; syncing and device backup do not cover identical content.
Consider it when: You want a separately controlled copy of computer files or a destination for Mac Time Machine.
Trade-off: You need to connect the drive and maintain the backup routine.
Consider it when: You have space on a Mac or PC and want a local iPhone or iPad backup.
Trade-off: Apple says local encryption is off by default, and a computer backup has content exclusions of its own.
Consider it when: You need to move or keep copies of particular documents or media files.
Trade-off: Manual copying will not automatically protect everything on the device.
| Concern | What to check | Who this matters to |
|---|---|---|
| Recovery and access | Check what your phone backs up, which computer folders are selected and what can be restored on a replacement device. | If I lose my phone, I want my photos and important settings back without relying on remembered manual copies. Roughly 29% of consumers put recovery and access first. |
| Local capacity and control | Allow room for the files you intend to retain; for Time Machine, Apple Support advises a disk with at least twice the Mac’s storage capacity. | I want an archive I control outside my cloud account, with enough room to keep it useful. For around 29% of consumers, a local copy and control over it are the main priority. |
| Portable large-file copies | Match the drive’s capacity and connection to your files and devices; check the conditions attached to quoted speeds and protection ratings. | When I regularly move large photo or video folders, I need storage that fits how I carry and connect it. Approximately 21% of consumers prioritise that portable-file need. |
| Cloud storage limits | Review current account use, which services share the allowance and whether the files you need are backed up or merely synced. | I do not want a full account to interrupt new backups while other services use the same allowance. That storage-limit concern comes first for roughly 21% of consumers. |
Apple Support distinguishes data synced to iCloud from data included in an iCloud device backup. A file appearing on several devices does not, by itself, establish what a particular backup can restore.
List the photos, documents, messages and settings you would need after replacing a device, then check the included and excluded content for your chosen route.
Samsung says the quoted maximum speeds for its T7 Shield depend on a compatible USB 3.2 Gen 2 host, cable and UASP mode. Drive connections and file-system requirements also matter when files move between operating systems.
Check the ports, supplied cable and file-system requirements before moving irreplaceable files; do not reformat a drive holding your only copy.
Apple Support says computer-based iPhone and iPad backups are not encrypted by default. The encryption password is needed if you later restore an encrypted backup.
If you enable encryption, retain the password securely and confirm that the backup completed.
Google Drive Help says Google account storage is shared across Drive, Gmail, WhatsApp backups and Google Photos. A photo library is therefore not the only use of that allowance.
Review total account usage before choosing how much cloud storage you need, and check that new backups continue to complete.
The T7 Shield line is relevant when comparing compact external SSDs for portable local copies.
The Extreme Portable SSD line is relevant to consumers comparing portable storage for frequent file transfers.
The My Passport portable hard-drive line is relevant when planning a larger local archive.
These external drives offer ways to keep local copies, while the USB-C phone drive suits selected-file transfers. Check the backup method supported by your own phone or computer before choosing a storage device.

Consider this for a portable local copy when you want storage to use with a compatible phone or computer; confirm your intended backup workflow before relying on it.
The product name specifies USB 3.2 Gen 2 and quoted speeds of up to 1,050MB/s read and 1,000MB/s write. Check your device connection before expecting those speeds, and check the fit of the magnetic set with your phone and case.

Consider this computer-connected drive for a larger local archive of photos and documents. If you want scheduled copies, check the software setup and which folders it will cover.
For macOS use, check the applicable driver and file-system requirements before putting existing files on the drive; also confirm how you would back up a phone if that is part of your plan.

Consider this for a portable local copy of personal files, provided your computer or other intended device supports the connection and backup method you need.
The product name specifies USB Type-C 3.2 Gen 2 (3.1 Gen 2). Confirm file-system requirements before sharing the drive between devices, and do not treat the T7 Shield line’s water-resistance claim as protection against immersion.

Consider this for copies of selected phone photos and videos rather than assuming it will back up an entire device.
Check your phone’s USB-C compatibility and the app requirements. Compare its 256GB capacity with the files you intend to keep on it.

Consider this for a computer-connected local archive when 4TB of storage fits the files you intend to copy.
Check the connection and file-system requirements for each computer you will use, particularly before reformatting the drive. Confirm a separate phone-backup method if you need to protect device settings as well as files.
Yes, an external drive can hold a separately controlled copy of computer files or serve as a Mac Time Machine destination. Check both copies independently: Apple Support says data already synced to iCloud is excluded from an iCloud device backup, while computer backups have different exclusions.
No. Apple Support describes iCloud and Mac or PC backup routes for iPhone and iPad; computer-backup encryption must be enabled separately. Google Android Help describes backup to a Google Account and says restoration can vary by phone and Android version, so check the content and restore steps for your device.
Apple Support advises a storage device with at least twice the Mac’s storage capacity for Time Machine. That guidance is specific to Time Machine, not a capacity rule for a drive used only to copy selected files.
A full Google account can affect new Google Photos backups. Google Drive Help says the storage allowance is shared with Drive, Gmail and WhatsApp backups, so review usage across the account rather than checking the photo library alone.
