Who needs which arrangement?

Households needing local control

If photos must remain usable when the connection is down, check whether the files are actually stored on your computer rather than shown as online-only placeholders. Microsoft Support describes how to keep selected OneDrive files on the device; Google Drive Help says mirroring keeps files both locally and in the cloud.

Families protecting irreplaceable memories

If accidental deletion or a lost device is the main worry, look for a separate copy with a restore process. Apple Support says iCloud Photos deletions carry across devices, while Backblaze Help documents a defined period for recovering earlier file versions.

Multi-device households ready to manage storage

A network-attached storage device, or NAS, can provide a shared local destination if you are prepared to manage its disks, access and backup tasks. Synology Knowledge Center documents backup destinations including external drives, another NAS and cloud services.

What to check before choosing

For local access and recovery after a home incident, decide where the working files will live, then choose a separate backup destination and check how restores work. A directly attached drive or NAS can serve the local role; an independently retained off-site copy addresses a different risk.

ConcernWhat to checkWho this matters to
Local file access Check the service’s offline or mirroring setting and whether the device has room for the complete local library. If I need photos during an outage, I want the files on my device, not just visible as placeholders. Around 33% of consumers put local access and control first.
Recoverable copies Check the backup’s off-site destination, restore window and treatment of changed or deleted files. Years of photos would be difficult to replace after a deletion or home incident, so I need a separate copy I can restore. Recovery is the primary concern for around 27% of consumers.
Capacity and copying Measure the library in GB or TB, allow for growth and check the drive connector against the computer. My collection is growing, and a copying routine needs to remain practical as it grows. Around 20% of consumers chiefly prioritise capacity and straightforward transfers.
Privacy and portability Check encryption and recovery-key arrangements, device compatibility and cloud-folder sharing permissions. If I carry a copy or share folders with family, I want to control who can open the files without losing access myself. Privacy and portability come first for around 20% of consumers.

Backup mistakes to avoid

  • Treating a synchronised folder as a separate backup

    Changes can travel to every synced location. Apple Support says deleting a photo from one device deletes it everywhere iCloud Photos is used.

    Keep a separate backup with a known retention period, then test restoring both a file and an earlier version.

  • Assuming a visible file is stored locally

    Microsoft Support explains that OneDrive Files On-Demand can show files without downloading them. Such files need a connection until they are made available offline.

    Set priority folders to remain on the device and confirm they have downloaded before relying on them away from the internet.

  • Overlooking retention and disconnected drives

    Backblaze Help documents a default 30-day version history. Backblaze also says an external drive disconnected for more than 30 days may be removed from its backup under the default retention arrangement.

    Check the service’s restore window and external-drive rules, and reconnect included drives within its stated requirements.

  • Reformatting or encrypting without planning recovery

    Apple Support warns that encrypting a storage device through Disk Utility can require erasing it first. A password or recovery key that cannot be retrieved can also make an encrypted copy inaccessible.

    Copy existing files elsewhere before formatting, check which devices must read the drive and keep recovery information securely apart from it.

Relevant brands and services

Microsoft

OneDrive is relevant when a household uses Microsoft accounts and needs to distinguish online-only files from folders kept on a computer.

  • Microsoft Support says Files On-Demand lets users mark selected files and folders to remain available offline.
  • Keeping a synced file locally is not the same as creating an independent backup; check the account’s restore options separately.

Google

Google Drive for desktop offers a choice between primarily cloud-stored streamed files and a local mirror.

  • Google Drive Help says mirrored files are stored on the computer and in the cloud and are available offline.
  • Mirroring synchronises changes, so keep a separate recoverable copy if mistaken changes are a concern.

Apple

Apple’s iCloud Photos and Time Machine serve different roles for households using Apple devices: synchronising a photo library and backing up a Mac.

  • Apple Support documents Time Machine use with directly attached drives and compatible NAS devices.
  • Apple Support says iCloud Photos deletions apply wherever iCloud Photos is used and advises keeping backup copies of the library.

Backblaze

Backblaze Personal Backup is an off-site backup option for a computer and eligible connected external drives.

  • Backblaze Help documents restoration of retained earlier or deleted file versions, with 30 days of version history by default.
  • Backblaze says a drive disconnected for more than 30 days may be removed from its backup under the default retention arrangement.

Synology

Synology NAS devices are relevant when several household devices need shared local storage alongside a separate backup destination.

  • Synology Knowledge Center documents Hyper Backup destinations including attached external storage, another NAS and cloud services.
  • A NAS needs hardware, disks and ongoing administration; a copy held only on the NAS remains at the same home location.

Local drives for family files

These directly attached drives can provide a local destination for family photos and files. Choose capacity and device compatibility for your library, then arrange a separate recoverable copy away from the home if you need protection beyond the drive itself.

Common questions

Is iCloud Photos, OneDrive or Google Drive automatically a backup?

No: synchronising files for access does not automatically create a separate recoverable copy. Apple Support says iCloud Photos deletions apply across devices; check each service’s restore and retention behaviour, and keep an independent backup for files you cannot replace.

How do I keep cloud-synced folders available offline?

Select the provider’s local-storage option and allow the files to download. Microsoft Support describes OneDrive’s “Always keep on this device” setting, while Google Drive Help says mirrored files remain on the computer as well as in the cloud; make sure the computer has enough space.

What should I test before relying on a new backup?

Restore several files to a different location and open them, then check whether you can recover an earlier version or a deleted file. Confirm that the intended folders are included and that the restore window covers the mistakes you are trying to protect against.

Can Time Machine use an external drive or NAS?

Yes, for compatible destinations: Apple Support documents directly attached drives and NAS devices that support Time Machine over SMB or AFP. Check the disk format before setup and copy off existing contents before any required reformatting.
