Start with your device ecosystem’s backup or transfer method, then add removable storage when you need an independent copy or a practical way to move large files. Check what the route restores, whether media stays at the quality you need, whether the new device is compatible, and whether you can open or restore representative files before erasing the old device.
Choose a route that restores the data you rely on, then complete a separate erasure process for the old handset. Apple Support and the Information Commissioner’s Office place backup or transfer before removal of personal information.
Distinguish copied folders from restoration of settings, apps and account-linked content, then verify representative files before disconnecting or erasing the previous computer. Microsoft Support and Apple Support describe different restoration and file-transfer steps.
Consider whether a cloud account, physical storage or a managed household NAS preserves original files and provides accessible capacity, rather than choosing media by advertised capacity alone. National Cyber Security Centre, Google Photos Help and Synology documentation describe the relevant backup routes and conditions.
Work out what must return on the replacement device first, then choose the storage route, capacity and connection that support that plan.
| Priority | What to check | Your needs |
|---|---|---|
| Restore scope | Check whether the route restores files only or also settings, apps and account-linked data. For Apple computer backups, confirm encryption if Health and Activity data must transfer. Check Android version compatibility and the intended account. | I need the replacement device to bring back more than folders and photos, including the data I use every day. |
| Verification before erasure | Browse copied folders on removable media, check cloud-backup completion, and confirm the backup date and size where the platform provides them. Open representative files before wiping the old device. | I want proof that the intended files or backup are accessible before I trade in, reset or disconnect the old device. |
| Capacity and media quality | Compare usable destination space with the data you intend to keep. For cloud photo backup, check the selected quality setting, supported file types and upload conditions. | My photo and video library needs enough room, and I do not want a setting to reduce media quality unexpectedly. |
| Security and disposal | Check the password or encryption workflow for sensitive copied files. Keep the outgoing device until the backup is confirmed, then follow its supported process for removing personal information. | I need to protect private files during the move and avoid leaving personal information on a device I sell, dispose of or hand down. |
A large drive can hold files without restoring phone settings, apps, messages, health data or account-linked information. Apple, Google and Microsoft support different restoration scopes and prerequisites.
List the data that must return on the replacement device, then check the operating-system backup method for each category before choosing capacity or media.
A backup may be incomplete, linked to the wrong account or missing files that did not copy successfully. Once the original is erased, the missing data may no longer be available.
Open representative files from removable media, check backup status in the relevant cloud service and, where applicable, confirm the backup date and size before deleting personal data.
Samsung’s stated T7 Shield performance figures depend on USB 3.2 Gen 2, UASP and a compatible host and cable. A mismatched port or cable can reduce transfer performance.
Check the exact drive model, your computer’s port specification and the included or replacement cable before choosing a high-speed SSD.
A removable drive or NAS can be lost, damaged or affected by the same incident as the original device. Synology documentation supports using multiple destinations and integrity checks.
For irreplaceable data, retain a separately accessible copy and periodically check that it can be restored rather than relying on storage capacity alone.
A first-party iPhone and iPad transfer and backup route for people staying within the Apple ecosystem, using Quick Start, iCloud or a computer backup.
A first-party Android and Google Photos route for users moving between supported Android devices or preserving selected photos and videos in a Google Account.
A Windows and OneDrive route for personal Windows users moving files, selected settings and many installed apps to a new PC, with external storage as an alternative for file transfers.
A portable SSD option for buyers seeking an exact-model, high-speed physical transfer drive with a rugged-design claim.
A portable external-hard-drive route for buyers whose backup set needs high physical capacity and compatibility with desktop backup tools.
A NAS route for technically willing households wanting central storage, scheduled versioned backups and a second backup destination.
Joybuy product options for creating a separate physical copy of selected files, moving larger computer libraries or building a managed household backup destination. Confirm your device ecosystem’s restore process separately where you need settings, apps or account-linked data to return.

Consider this portable SSD for a separate file copy between compatible Mac, PC and Android devices.
Stated 1TB capacity, USB-C connectivity and USB 3.2 Gen 2 support. Samsung’s stated maximum 1,050/1,000 MB/s read/write speeds require a compatible host, cable and UASP. Password protection and AES-256 encryption use Samsung’s software workflow. This is a file-copy route, not confirmation that phone settings, apps or account-linked data will restore.

Suitable for copying a substantial library of photos, videos and documents to a separate local destination before replacing a computer.
Stated 2TB capacity, USB 3.2 Gen 1 connectivity, scheduled-backup software and password-enabled 256-bit AES hardware encryption. It is pre-formatted for Windows; the listed macOS read/write use requires a driver workflow. Browse copied folders and open representative files before erasing the old device.
No image available
A focused option for selected photos, videos and documents from compatible USB-C iPhone, iPad and Mac devices.
Stated USB-C connection, 256GB capacity, up to 150 MB/s read speed and companion-app file management. The listing’s automatic-backup statement is limited to photos and videos; check exact device compatibility, app requirements and whether 256GB covers the files you intend to keep.

Consider this for a large, separate local copy of photos, videos and documents when moving between Windows computers.
Stated 4TB capacity, USB 3.2 Gen 1 5Gbps interface, USB-A cable and Windows 10+ recognition. The listing says other operating systems may require reformatting, and the drive is not stated to be waterproof or dustproof. It is a manual file-copy route rather than a complete device restore.

A household option for centralising backups across several devices when you are prepared to configure and maintain the system.
The listing states automated backups to cloud services, external drives and remote NAS, plus RAID redundancy, snapshots and remote access. This unit is diskless, so compatible drives, capacity and installation are required. RAID and snapshots do not replace a separate backup destination.
Not by default. The National Cyber Security Centre lists USB sticks, SD cards and external hard drives as backup locations, but the included data depends on the backup method. Check the phone maker’s documentation for settings, apps, messages and account-linked data; a manually copied drive is normally evidence of copied files rather than a complete device restore.
Create the backup, transfer information to the new device and only then remove personal information from the old one. Apple Support advises checking the date and size of a computer backup; use an encrypted backup when Health and Activity data must transfer.
Google Photos must be enabled for the correct account, and folders from other apps may need to be selected separately. Check backup completion and the backed-up marker on representative photos or videos before resetting the old phone.
No. Google states that restoration varies by phone and Android version, and a backup from a higher Android version cannot be restored to a phone running a lower Android version. Check the new device’s Android version and its manufacturer’s setup guidance before relying on the backup alone.
It can be, provided you check the selected quality setting and available storage. Google Photos says Original quality retains captured resolution, while Storage saver can resize photos above 16 MP and videos above 1080p; supported file types and size limits also apply.
