For automatic copies away from your device, consider its supported cloud backup; for a direct local copy of a large library, consider a compatible external drive. A USB flash drive can hold selected files, while a network-attached storage system may suit several household devices. Before erasing the original, check what you can actually restore and keep an important copy separate from the device, as the National Cyber Security Centre advises.
If you need photos, contacts, messages and supported settings on a new iPhone, iPad or Android device, check the old device’s backup before starting setup. Apple and Google document different restore steps and content limits; app support and software versions can also affect what returns.
Check how much space your photos, videos and documents use before choosing cloud capacity or a drive. A direct transfer to an external SSD may fit your workflow if the device, port and cable are compatible; rated drive speed alone cannot establish how long the transfer will take.
If losing the device would also mean losing family photos or important documents, plan for a recoverable copy kept separately. The National Cyber Security Centre recommends storing backups in a separate safe location; confirm that you can access the account or open files on the backup before resetting the original.
Choose the recovery route before choosing storage capacity: moving files to a new device, recovering after loss and maintaining copies for several computers place different demands on a backup.
Consider it when: You want a platform-supported backup available during replacement-device setup or after the original is lost.
Trade-off: Restoration depends on the account, available storage, connection and the platform’s rules about included data.
Consider it when: You want a direct local copy of a photo or file library before a repair, reset or replacement.
Trade-off: You must connect a compatible drive and keep it apart from the original device if one incident could affect both.
Consider it when: You need a deliberate export of selected documents or photos and its connector and capacity fit the task.
Trade-off: Check that the copied files open; carrying a small drive does not make it an independent copy if it can be lost with the device.
Consider it when: Several household computers need centrally managed storage and scheduled backups.
Trade-off: Setup and maintenance remain your responsibility, and a NAS also needs a separate backup destination for location resilience.
Consider it when: Photos or documents would be particularly difficult to replace and you do not want to depend on one device, account or location.
Trade-off: Each copy needs to be kept current and checked for recovery; adding destinations is not a guarantee against every failure.
| Concern | What to check | Who this matters to |
|---|---|---|
| Restoring a replacement device | Check the platform’s backup contents and when restoration must happen during setup. Apple says an already configured iPhone or iPad must be erased to use its backup-restore setup flow; Google says not all Android apps restore all data. | I need the new device to recover the information I rely on, not just my photo library. Around 33% of consumers put restore coverage first. |
| Large-library capacity | Measure the files you intend to copy and allow for growth. If choosing a drive, check its capacity and your device’s port and cable; a rated transfer speed is conditional on the connection. | With a substantial photo or video library to move before the old device goes away, I need enough room and a workable transfer route. Around 25% of consumers make library capacity and transfer their primary concern. |
| Recovery after loss or damage | Check the latest successful backup and whether you can access the account or open selected copied files. Keep a removable copy separately when the original and drive could otherwise be affected together. | If my phone or computer is lost, damaged or reset unexpectedly, I need a copy that survives without it. For around 25% of consumers, that resilience comes first. |
| Several household devices | Check support for each device, the space needed for ongoing backups and who will manage recovery. For a NAS, confirm the selected model’s backup features and its separate destination. | When several computers need regular copies, I want one manageable arrangement rather than an isolated transfer for each device. Around 17% of consumers prioritise shared, ongoing storage. |
A planned transfer may help with an upgrade, but it cannot replace an independent copy if the old device becomes unavailable before the move finishes.
Make a separate backup before a reset, trade-in or repair, then check its date and open a few important files.
Apple documents content excluded from particular backup methods, while Google says not all Android apps can restore all settings and data. A file may also be held by a separate sync service rather than in the device backup.
Check critical apps, downloads, account access and the platform’s backup inclusions before erasing the source device. Apple requires an encrypted computer backup for certain Health, Activity and Keychain data.
A growing photo or video library can outgrow the space chosen for its next backup.
Measure the files to be protected, then allow room for growth and any backup history you intend to retain.
Samsung says its T7 Shield’s maximum transfer rates require compatible USB hardware, cable and host support; the rating alone does not predict a particular copy time.
Check the exact drive model, device port, cable and required transfer mode before choosing a drive for a time-sensitive move.
Apple’s iCloud and local backup tools matter when moving an iPhone, iPad or Mac, but the method changes what is included and how restoration works.
A Google Account is a cloud-backup route for supported Android device data before replacement.
Windows Backup is relevant when changing a personal Windows PC and using a personal Microsoft account.
Samsung’s portable SSD range provides examples of removable storage for direct local copies; connection requirements are model-specific.
Synology is relevant to households considering a compatible NAS for centrally managed, ongoing backups.
These portable SSDs and hard drives are options for copying photos and files locally before a device change. Check your used storage, the exact device connection and how you will keep the completed copy separate; a drive does not replace your phone’s or computer’s platform-specific restore steps.

Consider this portable SSD for a direct copy of a large file library if its connection works with your device. The title specifies 4 TB and USB Type-C 3.2 Gen 2; check your port, file-system requirements and available storage before transferring. Keep this T7 away from liquids.
No image available
This is another portable local-copy option for a substantial file library. Its title specifies 4 TB, USB Type-C and USB 3.2 Gen 2x2; check whether your device supports that interface and the required file system before relying on it for a transfer.
No image available
Consider this portable hard drive for a local copy of photos and documents that fit within its 2 TB capacity. The listed NTFS formatting means macOS read/write use requires a downloadable driver; check that arrangement and your device connection before choosing it.
No image available
This portable hard drive is a local-copy option for a Mac photo or file library that fits within 5 TB. It is listed with HFS+ formatting; the stated Windows 10+ use requires a downloadable HFS+ driver, so check your intended devices before copying files between systems.
No image available
Consider this portable SSD when the files you intend to copy fit within 2 TB. Its title specifies USB Type-C and USB 3.2 Gen 2x2; check the destination device’s interface and file-system support rather than assuming the same transfer conditions on every device.
Yes, but Apple says its standard backup-restore setup flow requires erasing an iPhone or iPad that has already been configured. Check the backup’s date and size before taking that step, and confirm which content the chosen iCloud or computer backup includes.
No. Google says not all apps can back up or restore all settings and data, and its direct-transfer guidance lists additional exclusions. Check important downloads, app data and account access separately before erasing the old phone.
An SSD can hold a local copy, but it may not protect your files if it is the only copy or is kept with a lost or damaged device. The National Cyber Security Centre advises keeping important data in a separate safe location; open selected files on the drive and consider another location for irreplaceable data.
Yes. Apple says Time Machine can automatically back up Mac files to an external or network location and recommends a destination other than the Mac’s internal disk. Check that the destination is connected when needed and that the backup you plan to use can be restored on the intended Mac.
