What matters when choosing a backup?
The NCSC recommends regular backups of important files and checking that they can be restored. Compare each option by what it covers, how it stays up to date and whether a copy is kept apart from the device it protects.

What to check when buying |
Who this matters to |
| Routine copying and recovery |
Check which folders and device data are included, when the last copy completed and how to restore a sample file. |
If new photos arrive on my phone every week, I want recent copies I can retrieve after losing or replacing it. About 31% of consumers put routine copying and successful recovery first. |
| Capacity and ongoing cost |
Compare current used space with the exact drive capacity or plan allowance, and check what happens if a cloud plan is downgraded. |
When a family archive keeps growing, I need enough room for its photos and videos without losing track of the plan's limits. About 25% of consumers prioritise archive capacity and continuing cost. |
| Transfers and device compatibility |
Check the ports, supplied cables, host-device support and whether a drive may need reformatting. |
If I regularly move large folders between a phone and computer, I need a connection that works with both devices and a manageable copying routine. About 19% of consumers focus first on transfers and compatibility. |
| Shared storage and upkeep |
For a NAS, check supported drives, access for household devices, configured backup jobs and a separate destination for the NAS backup. |
When several people need a shared home file store, I want one I can set up and maintain, with a way to recover its files. About 13% of consumers put shared storage and its upkeep first. |
| Privacy and account access |
Check sharing settings, the product's encryption arrangements and how account or encryption recovery works. |
If private household files are stored online, I want to control who can access them and still have a workable way back into my account. About 12% of consumers prioritise privacy and access recovery. |

Backup questions answered
Is copying photos to a USB stick once the same as ongoing backup?
No. A one-time copy will not include photos taken later. Set a repeatable copying routine, disconnect removable backup media when it is not in use and check that you can restore a file. This is NCSC guidance, not a legal requirement.
What should I check before relying on phone-to-cloud copying?
Check the service's backup status, which folders and device data are included, available storage and account recovery. For iCloud Photos, Apple says photos are not also duplicated in iCloud device backup, so plan another copy if you need one.
Will a NAS with two drive bays replace a separate backup?
No. Synology warns that RAID crashes and drive failures can still cause data loss, and recommends backing up NAS data to a different destination. A NAS needs a separate recovery plan.
What happens to cloud backup if I cancel a plan or exceed its storage allowance?
It depends on the service's terms. Apple says that if an iCloud+ downgrade leaves storage over the new allowance, syncing and iCloud backups stop until space is freed or capacity is increased. Microsoft says OneDrive cannot upload, edit or sync new files while over its quota. Check your own plan before changing it.
Can family members automatically see my files when we share cloud storage?
Not necessarily. Google says other members cannot access a Google One family member's files without permission, and Apple says family members' personal iCloud+ files remain separate. Check the chosen service's sharing settings; a shared storage allowance does not necessarily create a shared photo library.
