Choose based on what needs to be recoverable and from which devices: an external drive suits a deliberate local copy, cloud backup suits automatic off-site copies for supported devices, and a NAS suits households that want shared home storage and accept setup and maintenance. For irreplaceable files, keep a separately recoverable copy rather than relying only on sync, an always-connected drive or a NAS restore point, and test how restoration works.
You keep family photos and household documents on one or more PCs or Macs and need a copy that can be restored after hardware failure, loss, theft, accidental deletion or malware. The National Cyber Security Centre explains that a backup is a separate copy that can be restored when the original data is unavailable.
Most new photos originate on iPhone or Android devices, while documents may live on a computer. Check whether camera-roll backup, device backup and computer-file backup are separate features in the ecosystem you choose.
Several people or devices need access to one home photo and document library, and you are prepared to manage network-connected storage alongside an additional external or cloud backup.
Start with the data you need to restore, then check device coverage, separation from the main device and the practical recovery process.
| Priority | What to check | Your needs |
|---|---|---|
| Recoverability | Check that the route creates a separate copy and has a documented restore method. Review version retention and how individual files can be recovered. | I need a copy that can be restored when the original device or file is unavailable, rather than a second folder that may have been overwritten. |
| Automatic coverage | Confirm whether backups are continuous, scheduled or manual. Check operating-system support, phone coverage, selected folders and exclusions. | My photos, documents, computers and phones should be covered without relying on everyone remembering manual copies. |
| Separate location | Keep at least one copy away from the main device or home. Disconnect a local backup when it is not in use, and secure cloud accounts with strong credentials and available multi-factor authentication. | I want one copy that is not exposed to the same device failure, theft, fire or connected-drive ransomware incident as the main computer. |
| Capacity and retrieval | Calculate storage against the existing library, expected growth and retained versions. Check subscription allowances, renewal terms and whether recovery depends on downloading from the internet. | I need room for current photos and documents as they grow, while knowing whether storage is a one-off purchase or an ongoing subscription. |
| Privacy and access | Verify encryption or password protection for the exact model. For shared NAS storage, check user accounts, folder permissions and recovery-key arrangements. | I want private photos and household documents protected if a portable drive is lost or several people use shared storage. |
A local drive can be affected by the same incident as the computer when it stays connected. A NAS in the same home is also one physical location unless it is copied elsewhere.
Keep at least one separately recoverable copy off-site or offline, and periodically confirm that files can be restored.
The only backup copy can be lost in the same ransomware, theft, fire or drive-failure event as the original.
Capacity must allow for the current library, future growth and retained versions. Maximum SSD speeds may require a particular USB host configuration, and some drives may need reformatting for different operating systems.
Measure the current photo and document library before buying, allow headroom, and check the exact model's capacity, connector, filesystem and host-device requirements.
Apple distinguishes synced iCloud data from iCloud Backup, while Google Photos backup has account and file-type conditions. A photo service is not automatically a full computer or phone recovery plan.
List the data to protect, including camera-roll photos, app data, household documents and computer folders, then check each category against the service's current scope.
A paid cloud tier may be needed when the included allowance is insufficient, and uncovered categories may need another backup method.
Synology says BeeStation restore points are not a replacement for full backups and recommends backing up BeeStation data to an external location.
Treat internal snapshots as a convenience for recent recovery, then plan and test a separate external, remote NAS or cloud backup destination.
A full backup destination may require additional external storage or cloud capacity, as well as time to configure and test it.

For shared household photo and document storage when you plan a separate backup destination as well.
No. Apple distinguishes syncing from backup: synced iCloud data is kept up to date across devices, while iCloud Backup takes snapshots of data that is not already syncing. Sync or mirroring can still be useful, but check version history and keep an independent copy because edits or deletions can also be reflected elsewhere.
Not if it is your only separate backup. The National Cyber Security Centre says ransomware incidents have affected connected USB and network drives holding backups, so keep at least one backup offline or digitally disconnected when it is not in use. If automatic local backup is important, add a separate off-site or cloud copy rather than relying on a permanently connected drive alone.
Only when the relevant backup or sync features are enabled and the item is within the service's coverage rules. Apple says iCloud Backup includes data not already syncing to iCloud, while Google Photos backup uses one Google Account and has file-size and format conditions. Check the account, allowance, selected phone folders and separate computer-file backup arrangement.
For a purely personal or household activity with no professional or commercial connection, the Information Commissioner's Office says the activity is outside the UK GDPR's scope. This does not automatically apply where the backup is used for business, professional or commercial purposes.
Yes, particularly if the drive could be lost or stolen. The Information Commissioner's Office says encryption is especially effective at protecting stored information from unauthorised access in that situation. Store the password or recovery key safely and separately, because losing it can also prevent access to important files.
