Local-copy-first photo keepers
You want photos and documents available from your computer or a connected drive, including when you cannot reach a cloud service.
Who this is for
Cloud backup users
You value syncing and access across devices, but need to know which files are available offline and how your service handles recovery.
Portable archive updaters
You move an up-to-date copy between devices or locations and need storage that is practical to carry and protect.
What matters when choosing
Start with how you would retrieve your files if the computer failed: from a downloaded local copy, an off-site account, or both. Then size the storage for your library and decide how often you will update the backup.
| Concern | What to check | Who this matters to |
|---|---|---|
| Accessible local files | Confirm that the chosen folders contain downloaded files, not just online-only entries; check that the destination has room for the library. | If I need my photos and documents without internet, seeing their names in a sync folder is not enough. Around 40% of consumers put accessible local files first. |
| Off-site recovery | Check which folders sync automatically and how the service handles deleted files and account recovery. | I do not want a computer failure to take away my only copy, and I would rather not rely on remembering to connect a drive. Around 30% of consumers make off-site recovery and automation their primary concern. |
| Portable updates | Check the drive’s capacity and connection against your computer, and consider how you will protect a drive you carry. | When I move a backup between devices, I want updating it to fit my routine without leaving the drive unprotected. For around 20% of consumers, that portable workflow comes first. |
| Large home archive | Measure the existing library and allow for growth; decide where a fixed-location backup will be kept when it is not being updated. | My collection mainly stays at home, so accommodating the files matters more to me than carrying the drive. Around 10% of consumers prioritise capacity for a fixed-location archive. |
Backup mistakes to avoid
-
Assuming every visible cloud file is stored locally
Microsoft says OneDrive Files On-Demand can show online-only files in File Explorer. Apple says iCloud Photos on a Mac can keep smaller local versions when storage optimisation is enabled.
Set the files you need for offline use to download, then open a sample of original photos and documents from the local copy.
-
Leaving the only drive backup beside the computer
A connected drive may be affected by the same incident as the computer. The National Cyber Security Centre describes a backup approach with at least three copies on two devices, including one off-site.
Keep another copy separately for irreplaceable files, and disconnect a local backup between updates where practical. Check that you can restore files from it.
-
Assuming cloud recovery lasts indefinitely
Microsoft states that deleted files in personal OneDrive accounts can be restored within 30 days; whole-account rollback requires Microsoft 365. A Google Takeout archive may omit changes made between requesting an export and its creation.
Check the service’s deletion, account-recovery and export steps, and inspect a completed archive before relying on it as your local copy.

Choosing capacity before measuring the library
New photos, documents and downloaded exports add to the space a backup needs.
Measure the files you intend to copy, allow room for growth and confirm the usable capacity and compatibility of the exact drive you choose.

Common questions
Is cloud synchronisation enough to back up my photos and documents?
Cloud synchronisation can give you access to another copy, but it should not be assumed to provide an indefinitely recoverable archive. Check your service’s restore rules, keep a separate copy of important files and try opening files from that copy.
How do I keep OneDrive files available offline?
Mark the files or folders you need as always available on the device in OneDrive Files On-Demand. Microsoft Support says online-only files can appear in File Explorer without taking local storage, so check that the files you need have downloaded.
How can I make a local archive of Google Photos?
Use Google Takeout to request and download an archive, then check the completed files before treating them as your local copy. Google Photos Help warns that changes made between requesting the download and creating the archive may not be included.
How do I keep full-size iCloud Photos originals on my Mac?
Choose Download Originals to this Mac in Photos if full-size local copies are what you need. Apple Support says Optimise Mac Storage can retain smaller versions locally when space is limited, so confirm that the originals have downloaded before relying on them as a backup.
