Choose based on what you need to recover: a place to store photos and documents is not necessarily a service that restores device settings and app data. Match the storage to your file volume, device ecosystem and need for offline access, then check that the backup has completed and test representative files. For irreplaceable files, a separate local and off-site copy can help protect against different failure scenarios.
Who this is for
Phone replacers preserving memories
If you are changing or resetting a phone, check separately that your photos, documents and the device information you need will be available afterwards. Apple Support UK and Google Android Help describe different coverage and restoration conditions for their services.
People keeping a large local copy
If your photo and document collection is growing, choose capacity for the files you intend to copy and consider whether you need access without an internet connection. Apple Support UK’s Time Machine guidance and Seagate’s specifications describe different requirements for particular backup methods.
Households managing shared archives
If several people need an ongoing shared store, consider the setup and backup destinations you are prepared to manage. Synology’s guidance for NAS storage recommends a separate backup arrangement rather than treating the shared store as the only copy.
What to consider before choosing cloud storage or a drive
Cloud storage
Consider it when: you want files available across supported devices and can upload and download them.
Trade-off: paid capacity is an ongoing commitment, and online-only files need internet access.
A local drive
Consider it when: you want a copy stored locally for access without a cloud download.
Trade-off: you need to manage the drive and its compatibility; one drive is not an off-site copy.
Both local and off-site copies
Consider it when: losing irreplaceable files would be particularly difficult and you want copies kept in different places.
Trade-off: more destinations mean more storage and administration to keep the copies current and recoverable.
Before choosing, separate the need to restore a device from the need to keep copies of particular files. The checks below address the main decisions that can change which route fits.
| Concern |
What to check when buying |
Who this matters to |
| Recovering the right files and device information |
Check service coverage, backup completion and whether representative files can be restored. Apple Support UK and Google Android Help specify service and device conditions. |
Before resetting a device, I want to know which files and device information will return and to check a completed restore. About 29% of consumers put recovery first. |
| Capacity and photo quality |
Measure the files to copy and allow for the chosen backup method. Google Photos Storage saver compresses photos and resizes those larger than 16 MP; Apple’s twice-the-Mac-capacity guidance is specific to Time Machine. |
If my library is growing, I need enough space without changing the originals I value. About 24% of consumers prioritise capacity and photo quality. |
| Offline access and connections |
For cloud files, check whether they are downloaded for offline use. For a drive, check its connectors, operating-system support and any formatting requirements. |
When I may need files without internet, I want a local copy or files downloaded in advance. About 18% of consumers prioritise offline access and workable connections. |
| Ongoing commitment |
Check the cloud plan’s billing and storage allowance, the exact drive or NAS configuration, and what a separate backup destination would involve. |
If I want to keep files beyond a device change, I need to understand the continuing commitment, not just the initial purchase. About 17% of consumers prioritise ongoing cost. |
| Privacy and separate failure risks |
Check region-specific features, retain passwords needed for encrypted restores, read warranty exclusions and plan a separate destination for important files. |
If access control and recovery from a separate failure matter most to me, I need to plan beyond a single copy. About 12% of consumers put privacy and resilience first. |
Backup pitfalls to avoid
-
Buying more storage without checking what it covers
Photo storage, synchronised files and device backups can cover different things. Apple Support UK distinguishes iCloud Photos from the daily device backup, while Google Android Help describes conditions for restoring supported device data.
List the files and device information you need, check the service’s coverage, and test a representative recovery before resetting the original device.
You may pay for capacity that does not cover the files or device information you expected.
-
Treating cloud placeholders as an offline backup
Microsoft Support says OneDrive online-only files require an internet connection; they are not downloaded copies on your device.
Download the required files and verify that they open offline before relying on them during a device change.
Downloading files takes time and uses local storage.
-
Assuming a rugged drive or NAS replaces another copy
Samsung’s T7 Shield resistance claims are based on controlled internal testing, and liquid and dust damage are excluded from its warranty. Synology’s NAS guidance recommends a separate backup arrangement.
Treat physical resistance as one model feature, not a guarantee against data loss. For important files, plan another recoverable copy kept separately.
A separate destination can add hardware or subscription costs and needs managing.
-
Choosing a photo setting without checking its effect
Google Photos Storage saver compresses photos and resizes those larger than 16 MP to 16 MP, so it is not the same as Original quality.
Check the quality setting before uploading, and keep another copy of originals if retaining their captured resolution matters to you.
Relevant brands and product lines
Apple
Relevant to iPhone and iPad replacement through iCloud Backup and to local Mac backups through Time Machine.
- Apple Support UK distinguishes synchronised iCloud files from data stored in an iCloud device backup. Time Machine supports automatic local backups.
- An encrypted Time Machine restore requires its password. Apple Support UK says new UK users cannot enable Advanced Data Protection.
Google
Relevant to supported Android device restoration and Google Photos storage.
- Google Android Help describes restoration to the original or some other Android phones, subject to device and profile conditions.
- Google Photos Original quality and Storage saver are different settings; Storage saver compresses photos and resizes those larger than 16 MP.
Microsoft
OneDrive is relevant when you want cloud files accessible from a Windows computer and need to manage local versus online-only copies.
- Microsoft Support says Files On-Demand can reduce local storage use, and selected files can be kept available offline.
- Online-only files need internet access. Microsoft states that direct Samsung Gallery synchronisation with OneDrive ended on 30 September 2026.
Seagate
The Expansion Portable STKM2000400 is a 2TB black variant for USB-powered local storage.
- Seagate’s specifications describe file saving and Windows/macOS compatibility, subject to the user’s configuration.
- Seagate specifies reformatting for Time Machine. Check the exact drive and backup method before using it with valued files.
Samsung
The T7 Shield 1TB black MU-PE1T0S/EU is a model-specific portable SSD with USB 3.2 Gen 2 connectivity.
- Samsung’s IP65 resistance claim for this model is based on controlled internal testing.
- Samsung states that liquid and dust damage are not covered under warranty. The resistance claim does not remove the need for another copy.
SanDisk
The Ultra Dual Drive Go is relevant to moving selected files between supported USB-C and USB-A devices.
- SanDisk describes application-assisted file backup on macOS and Windows for the 1TB variant.
- Connector compatibility and file copying do not establish complete phone restoration. Check the exact model and capacity.
Synology
The DS223j is relevant to an ongoing shared file store managed at home.
- Synology’s guidance distinguishes a NAS from a separate backup destination and recommends keeping multiple copies, on different media, with one off-site.
- Confirm that the backup packages you need support the exact NAS model and software version; manufacturer guidance is not an independent reliability measurement.

Backup questions answered
Does iCloud Backup contain another copy of my iCloud Photos library?
Not when iCloud Photos is enabled. Apple Support UK says those photos are synchronised to iCloud and excluded from the daily device backup. Check the photo library and device backup separately before resetting your device.
How much space should I choose for a Time Machine drive?
Apple Support UK recommends a storage device with at least twice the storage capacity of your Mac and using the backup disk for Time Machine rather than other files. That recommendation applies to Time Machine, not every manual photo-copy workflow.
Could setting up a backup drive erase files already on it?
Yes. Apple Support UK says Time Machine setup may ask to erase the storage device, and Seagate specifies reformatting for Time Machine. Preserve valued files elsewhere first or choose another disk or volume.
Can I use OneDrive files locally without internet?
Yes, if the required files have been downloaded to the device. Microsoft Support says online-only files need internet access; mark the files or folders as always available, let them download and verify the local copies before relying on offline access.
Can a new UK customer enable iCloud Advanced Data Protection?
No. Apple Support UK says new UK users no longer have the option to enable Advanced Data Protection. Do not assume that global descriptions of optional iCloud end-to-end encryption establish availability for a new UK customer.
