Choose cloud storage if automatic, off-device copies and access after replacing a device matter most, but check what is included and how you would regain access to the account. Choose a removable drive for a local copy you can store separately; a NAS can serve several household devices, but it still needs another backup destination. For files you cannot replace, combining separated local and cloud copies avoids relying on just one route.
If a phone or computer is lost, fails or needs replacing, these households want to restore important files without having to remember to connect a drive. Apple's device-backup guidance and the National Cyber Security Centre's advice on keeping a separate copy are relevant starting points.
These households need room for photos, videos and documents, a way to restore them, and a removable copy kept away from the source computer. The drive's usable capacity and the backup tool's file coverage both matter.
A NAS can bring files from computers and phones into one home location. Synology's guidance also makes clear that the NAS needs a backup to another destination; central access alone does not make it the separate recovery copy.
For household photos, documents and device files, decide what you need to restore and where a copy will remain accessible if the original device is unavailable. Then check the capacity, compatibility and restoration steps for the route you choose.
| Concern | What to check | Who this matters to |
|---|---|---|
| Automatic off-device recovery | Check which files are synced or backed up, available account storage and the steps for restoring to a replacement device. | If my phone fails or is replaced, I want an up-to-date copy I can reach without connecting a drive. Around 36% of consumers put automatic off-device recovery first. |
| Space for a local archive | Compare the archive and expected growth with usable capacity; check ports, device support and, for a NAS, whether drives are included. | My photo and video collection keeps growing, so I need a local copy that fits and can be transferred from my devices. For around 29% of consumers, local archive capacity is the primary concern. |
| Separated copies | Check where each copy is kept and whether you can restore an earlier or deleted file; keep a removable drive disconnected when it is not being updated. | If an incident affects my computer and a connected backup, I still need another recoverable copy. Keeping copies separate comes first for around 21% of consumers. |
| Essential documents only | Define the file set, then check usable capacity, connector compatibility and how you will keep the copy separate and current. | I only need to preserve a small, identified set of documents, rather than a whole device or photo library. Around 14% of consumers prioritise this limited-file copy. |
The National Cyber Security Centre warns that an incident can affect original files and connected USB or network storage. A cloud account can also become inaccessible, so having a copy is not the same as being able to restore it.
Keep at least one recoverable copy separate from the original device. If you use a removable drive, disconnect and store it safely between updates, and try restoring a file before relying on the arrangement.
Apple distinguishes synced content from data captured in iCloud Backup: photos using iCloud Photos are synced, rather than included in the daily device backup.
List the photos, documents and other data you need to preserve, then check where each is stored and how you would restore it.
A growing archive and retained versions need room beyond today's files. For a NAS, Synology notes that usable capacity depends on the installed drives and RAID configuration.
Measure the files you intend to preserve, allow space for growth and check the usable capacity of the exact drive or NAS arrangement.
An off-device copy will be difficult to use if you cannot regain access to its account after losing a device.
Keep account recovery details current and make sure the household knows how the account owner can regain access.
iCloud and computer backup routes for households using iPhone or iPad, particularly when restoring a replacement device matters.
Account-based storage through Google One, Drive and Photos for households using those services or Android devices.
OneDrive file storage and recovery for households using Microsoft accounts or Microsoft 365.
External-drive storage with Toolkit backup options for compatible Windows households wanting a removable local copy.
Home NAS storage for households bringing files from several devices into one location.
No, they can cover different data. Apple distinguishes content synced through services such as iCloud Photos from data included in iCloud Backup. Check the restoration route for each important photo library, folder and type of device data.
Choose cloud storage when automatic off-device copying and access after device replacement are your priorities; choose an external drive when you want a local copy and can update and store it separately. For irreplaceable photos, using both routes reduces reliance on a single copy or account.
Do not rely on the connection alone: the National Cyber Security Centre describes ransomware affecting connected USB and network storage as well as original files. Keep a recoverable copy separate from active devices, and check the restoration options of any cloud service or backup software you use.
Restore a representative photo and document, open both files and confirm that the copy is kept separately from the original device. This checks the practical recovery step behind the National Cyber Security Centre's advice to store important data in a separate safe location.
