For family photos and files, cloud backup can make supported data available when you sign in on a replacement device, while an external drive gives you a removable copy separate from the old device. If the files are irreplaceable, use both locations where practical, and check that each backup has completed and that you can restore files before retiring the old device.
Check what your current account will restore before you erase or hand over the old device. Google says Android backups can restore supported data during setup; Apple’s iCloud Backup and Microsoft’s Windows Backup provide their own device-transition routes, with different content and settings covered.
Look for a way to capture new photos regularly and make the files available where family members need them. Google Photos and iCloud offer account-based routes; Synology describes phone-photo backup to its BeeStation home-storage device. Check whose account holds each library and how much storage it uses.
The UK National Cyber Security Centre describes a backup as a copy kept in a separate safe location, such as cloud storage or removable media. That distinction matters if a phone or computer is lost, damaged or unavailable during a changeover.
Consider it when: You want supported photos, files or device data available through an account on a replacement device.
Plan for: Checking which content is backed up, whether backup is enabled and how much account storage remains.
Consider it when: You want a local copy on a drive you can disconnect and keep separately from the device being replaced.
Plan for: Compatible connections, a repeatable copying routine and another location for files that must not depend on one drive.
| Priority | What to check | Your needs |
|---|---|---|
| A separate copy | Check where the backup is stored, whether copying has finished and whether you can open or restore selected files. Keep the backup accessible after the old device is gone. | I want my photos and documents to remain recoverable if the old device is lost, damaged or erased. |
| Moving to a new device | Confirm what the chosen phone or computer backup includes, which account is needed and what can be restored during setup. Check this before retiring the old device. | Signing in on a replacement device should give me access to the files I need, without assuming every app or setting will transfer. |
| Storage capacity | Measure the photos, documents and device data you intend to copy, then allow room for growth. Google says account storage is shared across services; for Time Machine, Apple recommends a disk with at least twice the Mac’s storage capacity. | Our photo library needs to fit alongside anything else using the account or backup disk. |
| Device compatibility | Check ports, cables, operating-system support and whether each device can read and write to the drive. For an SSD, check the connection required for any stated peak speed. | I need to move files between the devices we actually own, not just connect a drive to one computer. |
| More than one location | Check what a synced folder, version history or home-storage restore point can recover, and keep a further copy where needed. Synology says BeeStation restore points do not replace full backups. | If an account, drive or home-storage device has a problem, I still want another way to recover important files. |
A file available through one account is not necessarily an independent copy. The National Cyber Security Centre’s guidance calls for a copy in a separate safe location.
Keep another copy of irreplaceable files and try opening or restoring selected items before you give up the old device.
A cloud account may share its quota with other services. Google says reaching its storage limit stops new Google Photos backups; a computer backup also needs room for the data and retained versions.
Measure the backup set and check existing storage use. For a Mac using Time Machine, Apple recommends a disk with at least twice the Mac’s storage capacity.
Transfer and backup plans depend on the ports, cable and device support involved. Samsung’s stated peak speeds for its T7 Shield, for example, require a compatible host, cable and protocol.
Check the requirements of the exact drive and each phone or computer before relying on a direct transfer.
Synology says BeeStation’s internal restore points are not a replacement for a full backup to another location.
If you use home storage, plan a separate backup destination and check that files can be recovered from it.
These brand and service examples show different backup arrangements; check the exact service settings or product variant before choosing one.
iCloud supports photos, files and iPhone or iPad backups, while Time Machine backs up a Mac to external storage.
Google accounts offer Android device backup alongside storage used by Google Photos and Drive.
Windows Backup uses a Microsoft account for selected content on a new PC; File History can copy selected folders to an external drive or network location.
Samsung’s portable SSD range provides removable local storage for copying files between compatible devices.
Seagate describes its One Touch external hard drives as local storage for photos, videos and documents.
BeeStation Plus is a home-storage route that Synology says can collect content from phones, computers and other storage locations.
These external SSDs and portable hard drives are options for a removable copy of family files before changing devices. Measure what you need to back up, check connections with your devices and keep another copy of irreplaceable files.

A removable destination for a household photo and file copy before a device change. The name specifies USB 3.2 Gen 2x2; check your devices’ connections and measure the backup set before choosing the 4 TB variant.
No image available
This removable SSD offers a local destination for files from a compatible device. Check that the 2 TB capacity covers your backup set and that your devices can use its stated USB 3.2 Gen 2x2 connection.

Consider this removable drive for a separate copy of a larger file library after measuring what must fit. Its name specifies USB 3.2 Gen 2; confirm the connection and file access requirements of the devices you will use.

This external SSD can hold a removable copy if your selected files fit within 1 TB. Check the devices and cables for its stated USB 3.2 Gen 2 connection before planning a transfer.

A portable hard-drive option for a separate local copy of photos and documents. Measure the files you intend to store and confirm read, write and formatting requirements for each device before relying on the drive.
Cloud backup helps when you need supported files or device data through an account on the replacement device; an external drive gives you a removable local copy. For irreplaceable family files, use both locations where practical and check that you can recover files from them before retiring the old device.
Measure the photos, documents and other data you plan to back up, then leave room for growth. If the drive is for a Mac using Time Machine, Apple recommends at least twice the Mac’s storage capacity; that is a Time Machine recommendation, not a rule for every backup.
It can restore supported content if the relevant backup was enabled and completed. Google says backed-up Android data can be restored during setup; Microsoft describes selected content available through Windows Backup on a new PC, while Apple provides iCloud Backup for restoring or setting up an iPhone or iPad. Check what your own account and settings include before giving up the old device.
Yes, it can. Google says reaching its account storage limit prevents new Google Photos photo and video backups and affects other services. Check used space and everything sharing the account quota before starting a large device move.
Do not make a flash drive the only recoverable copy of irreplaceable photos. It can hold files for transfer between compatible devices, but the UK National Cyber Security Centre advises keeping important data in a separate safe location. Check the copied files and maintain another copy that you can recover if the flash drive is unavailable.
