For irreplaceable family photos and documents, use more than one backup location rather than relying on an external drive, NAS or cloud account alone. An external drive provides a local copy you can disconnect; a NAS can serve several household devices but still needs a separate backup; cloud storage can provide an off-site copy if its account, storage and deletion terms work for you. The UK National Cyber Security Centre advises keeping at least three copies on two devices, with one copy off-site.
If family photos and documents cannot be recreated, keep copies that will not all be affected by a device failure, theft or an incident at home. A copy in another location addresses a risk that local storage alone cannot.
A shared library can make files easier to access across devices. Check whether changes and deletions synchronise, who controls the account, and how you will keep an independent copy of the library.
A local drive or NAS gives you a way to restore files without downloading the whole library. Plan an off-site copy that you can update on a schedule your connection permits.
Choose how you will make a local copy and an off-site copy, then check that you can restore files from each. The UK National Cyber Security Centre recommends at least three copies on two devices, with one off-site.
Consider it when: You want a local copy you can disconnect and use without broadband.
Trade-off: A drive kept at home can be lost, damaged or affected by the same local incident as the original files.
Consider it when: Several people or devices need a shared local library and you are prepared to maintain the NAS.
Trade-off: Drive redundancy and versioning do not replace a separate backup; Synology warns that RAID crashes and drive failures can still cause data loss.
Consider it when: You need an off-site copy and can upload your library through your household connection.
Trade-off: Continued access depends on the account and its storage and retention terms; synchronised deletions may affect every connected device.
| Priority | What to check | Your needs |
|---|---|---|
| Separate copies | Identify where the working files, local backup and off-site copy will live. Check that one device or household incident cannot affect them all. | I want family photos to remain accessible if a computer, drive or storage location is lost. |
| Usable recovery | Restore a few photos and documents to check that they open. Where offered, check whether version history can recover an earlier file; keep an independent backup too. | If I delete or change a file by mistake, I need more than another synchronised copy of that change. |
| Capacity and service terms | Measure the library and allow for future files. For cloud storage, check shared quotas, over-limit and inactivity rules, and how to download a separate copy. | Our library needs enough room to grow, and I want a way to take a usable copy out of a cloud account. |
| Access and recovery | Decide who manages each account and backup. For encrypted cloud data, set up the available recovery methods and keep their details secure. | Family files should be protected from unwanted access without leaving the household unable to recover its account. |
Apple says that deleting a photo from a device using iCloud Photos also removes it from iCloud and other devices using the service. Synology warns that RAID crashes and drive failures can still cause data loss. Neither arrangement alone supplies an independent off-site copy.
Keep a separate backup destination and test that you can restore photos and documents from it.
A connected backup can be affected along with the computer during a malware incident. A drive kept in the same home also remains exposed to a local incident.
Disconnect a removable backup after use, store it securely and reconnect it on a schedule you can maintain. Keep another copy off-site.
Google says that content in a personal account inactive for at least two years may be deleted. Microsoft warns that OneDrive files might be deleted after six months under its storage-quota policy.
Check the terms for your account, monitor its storage use and practise downloading a separate copy before relying on the service as your only accessible location.
With Apple Advanced Data Protection, Apple does not hold the keys needed to recover end-to-end encrypted data for you.
Before enabling it, check device requirements and set up and safeguard a recovery contact or recovery key.
These services and NAS ranges illustrate different parts of a household backup arrangement; a brand name alone does not establish that your files have an independent, recoverable copy.
Google Photos and Drive may suit a household already organising files through a Google account.
iCloud Photos is relevant to households that synchronise a photo library across Apple devices.
OneDrive is a cloud-storage route for households using a Microsoft account.
Synology NAS models are relevant when a household wants shared local storage and is prepared to manage the device and its backup.
QNAP positions the TS-233 as a home NAS for central storage and collaboration.
These Joybuy portable SSDs are options for the local-copy part of a family photo backup. Check your library size and device connection before choosing one, and arrange a separate off-site copy for irreplaceable files.

For a local copy of a larger photo and document library, compare the stated 4 TB capacity with the space your files use and the room you need for new ones. The name specifies USB 3.2 Gen 2x2; check that your device has a suitable connection. Keep another copy off-site and test a restore.

This can hold a local copy if your library and expected growth fit within its stated 1 TB capacity. The name specifies USB 3.2 Gen 2x2; check your device connection. Disconnect the drive when it is not being used for backups, and retain an off-site copy.

The stated 2 TB capacity is worth considering for a local copy once you have measured your photo and document library. This variant is named as USB 3.2 Gen 2; confirm the connection you need. A copy on this drive still needs a separate off-site counterpart.

This USB 3.2 Gen 2 variant could serve as a local copy if the stated 1 TB capacity accommodates your files and future additions. Check the connection with your computer, keep an independent off-site copy and try restoring sample files.

This USB 3.2 Gen 2 drive is another local-copy option if your library fits its stated 1 TB capacity. Check the connection with your device and store a separate copy off-site; a portable drive on its own does not cover loss at the household location.
Not if it holds your only backup of irreplaceable files. A drive can fail or be affected by an incident at the same location as the originals. Keep another copy off-site, disconnect the removable drive when it is not backing up, and test that you can restore files.
Drive redundancy is not a substitute for a separate backup. Synology warns that RAID crashes and drive failures can still cause data loss. If you use a NAS for the family library, copy its files to another destination, including an off-site one.
Check your account’s capacity, shared-quota rules, deletion and inactivity terms, recovery methods and procedure for downloading a separate copy. Google documents data exports, while Microsoft documents consequences under its OneDrive storage-quota policy; apply the terms of the service and account you actually use.
Do not treat synchronisation alone as an independent backup. Apple says deleting content from a device using iCloud Photos also removes it from iCloud and other devices using the service. Keep a separate copy, particularly before deleting or reorganising a large library.
Set up and safeguard an alternative recovery method and check that your devices meet Apple’s requirements. Apple says it cannot recover end-to-end encrypted data for you because it does not hold the necessary keys.
