Choose automatic cloud backup if recovering a phone and accessing files across supported devices are your main concerns; choose an external drive for a local copy you can keep separately. A home NAS suits a shared household library if you are willing to manage its setup and back it up elsewhere. With any route, check exactly which files are copied and practise restoring them before relying on it.
Start with where your household keeps its files: a phone, one computer or several devices used by different people.
If photos and other important data live mainly on iPhones or Android phones, check what you could restore after a phone is lost, damaged or replaced. Family access to selected photos is a separate decision from backing up the device.
Photos and documents on PCs or Macs need their own coverage alongside phone data. Identify folders stored only on a computer rather than assuming that synchronised folders contain every file you would want to recover.
A common home storage location can help household members upload and share selected photos. It also brings responsibility for permissions, upkeep and a separate backup of that shared library.
Choose a destination for each important set of files, then check how the copy is made and restored. The UK National Cyber Security Centre describes a backup as a copy kept in a separate safe location, rather than simply another way to access the original.
Consider it when: Phone replacement and access through supported accounts matter more than keeping the only additional copy at home.
Trade-off: Storage allowances, account access and service conditions affect what can be copied and recovered.
Consider it when: You want a local copy of computer files that you can disconnect and store separately.
Trade-off: The drive has to be connected when copies are made, and its presence alone does not confirm that every folder is covered.
Consider it when: Several people need a shared home photo library and you can manage accounts and storage.
Trade-off: A NAS needs its own backup destination; Synology warns that drive failure or a RAID crash can still cause data loss.
| Priority | What to check | Your needs |
|---|---|---|
| Recovery | Check when automatic copies run, which account or device restores them, and whether you can open a restored sample file. | If my phone is replaced or my computer becomes unavailable, I want to know how to retrieve the files that matter. The UK National Cyber Security Centre identifies loss, damage and accidental deletion among reasons for keeping a separate copy. |
| Backup coverage | Review included photos, app data and folders. Apple Support says iCloud backups exclude information already synced to iCloud; Microsoft says other folders can be added to File History’s usual folder coverage. | I would check both phone content and computer folders, especially files outside the locations my backup service selects by default. |
| Capacity and access | Add up existing files across relevant accounts; check shared allowances, renewal terms and how you would move files out of a service. Google One Help states that up to 15 GB in a standard Google Account is shared across Drive, Gmail and Photos; Apple Support states that iCloud includes 5 GB. | A growing collection of photos and videos needs room for future copies as well as today’s files. I would also check who in the household uses each account’s allowance. |
| Family sharing | Check supported devices and accounts, who can upload or edit, and the permissions on shared folders or links. If the shared library lives on a NAS, arrange another backup destination. | We may want relatives to see selected photos without giving everyone access to the whole library or treating sharing as a second backup. |
| Local connections | Confirm ports, connectors, drive format and operating-system support before choosing removable storage. Decide when the drive will be connected and where a separate copy will be kept. | For files on a computer, I may prefer a drive I can store away from it. A USB flash drive or transfer accessory may help move files, but I would still verify the copy at its destination. |
Synchronisation keeps a library current across devices; it does not, by itself, establish that a separately recoverable copy exists. Apple Support says content using iCloud Photos is not included in the daily iCloud backup.
List your photos, documents, messages and computer folders, then check whether each is synced, backed up or stored only on its original device. Check how changed or deleted files can be restored.
A shared NAS remains one storage location. Synology warns that RAID crashes and hard-drive failures can still lead to data loss.
Set up a backup of the NAS to a separate destination, consider an offsite copy and test that you can restore files from it.
Apple Support states that iCloud includes 5 GB of storage; Google One Help states that a standard Google Account has up to 15 GB shared across Drive, Gmail and Photos. Compare an allowance with the accounts and files you actually intend to use it for.
Check current storage use, which family members share a quota, subscription terms and how you would export files before relying on automatic copies.
If the available allowance is too small, maintaining the chosen storage capacity may require an ongoing subscription.
A cable or charging hub connects devices but does not retain files. Removable storage can hold a backup if the files are actually copied and kept in a separate safe location, as described by the UK National Cyber Security Centre.
Copy files to the intended destination, open a sample there and keep the originals until you have checked the transfer.

A portable local destination for copying photos and documents from a compatible computer.
The listing specifies USB 3.2 Gen 1, bus power, scheduled-backup software and password-protected 256-bit AES hardware encryption. Check device compatibility and the files selected by your backup software; keep the drive still during transfers and eject it safely.
Image unavailable
A portable local destination for a larger collection of files, particularly where a Mac is the main computer.
The listing specifies USB-C, a USB-C-to-USB-A adapter, password protection and 256-bit AES hardware encryption. It specifies HFS+ formatting and says Windows use requires a downloadable driver; confirm the setup for your computers and the applicable warranty terms.
Image unavailable
A portable local storage option for moving or copying files using compatible USB-C devices.
The listing specifies 1TB capacity and a USB Type-C connection, and names PC, Mac and Android use. Confirm that your particular phone or computer can connect to, power and access the drive, then establish how you will make and verify a separate backup copy.
Image unavailable
A portable destination for making a local copy of files from a compatible computer.
The listing specifies 4TB capacity, a USB 3.2 Gen 1 connection and a USB-A cable. It says reformatting may be needed for Mac or other operating systems; check the format before copying files, protect the drive from physical shocks and retain another copy of important data.
Image unavailable
A stationary local destination for files from a computer kept near a desk and power outlet.
The listing specifies 10TB capacity, USB 3.2 Gen 1 and an included AC adapter. It describes Windows backup use and says macOS requires reformatting; confirm computer compatibility and which folders your configured backup will actually copy.
No, not necessarily. Apple Support says iCloud Backup excludes information already synced to iCloud, so check how your particular photo library and other files can be recovered after deletion or a device change. For important files, identify a copy kept in a separate safe location.
Apple Support says iCloud Backup must be enabled and an iPhone or iPad needs power, Wi-Fi, a locked screen and sufficient iCloud storage for an automatic backup. Check that a backup completes and review what it includes.
Google One Help says backed-up Android data can be restored during setup of another Android phone. Review the backup details first: photos and videos use Google Photos, and other backed-up data may be erased after 57 days of device inactivity.
Yes, Microsoft Support says File History can make regular backups to an external drive or network location once configured. Keep the destination available when copies are due, check that the folders you need are included and try restoring a file.
No. Synology warns that RAID crashes and hard-drive failures can still cause data loss, and recommends separate copies across storage media, including one offsite. If a NAS holds your household library, configure and test a backup to another destination.
