For work files or family photos that would be difficult to replace, use a separate local copy alongside an off-site copy rather than relying on one drive or a synchronised folder alone. Choose file sync for access to current documents, and a device-backup workflow when you need to restore a phone; in every case, check what is included and test how you would retrieve it.
If photos and videos are spread across phones and computers, look for a separate copy and a way to retrieve individual files. If replacing a lost phone matters too, check the device-restoration workflow separately from photo storage.
Current documents may need to be available on several devices, but access alone does not answer how to recover an earlier version or restore files after a device replacement. Check both sync and recovery features.
Several computers and phones can call for substantial local storage. A shared NAS may suit a household willing to manage its setup, provided important files are also copied to another destination.
For personal, household, study and self-employed files, decide what you need to recover before choosing where to store the copy. The National Cyber Security Centre describes a separate safe location as central to backup; convenient access to a file is a different need.
| Concern | What to check | Who this matters to |
|---|---|---|
| Independent recovery | Keep a copy separate from the main device and test restoring a representative folder. Consider an off-site destination for a local incident. | If losing a computer would also mean losing important work or family photos, I need a copy I can restore independently; about 27% of consumers put recovery after loss or damage first. |
| Access across devices | Check supported devices and the service's version-history and deleted-file recovery rules. | When I edit a document on both my computer and phone, I want the current file within reach without losing the ability to recover an earlier version; about 27% of consumers prioritise cross-device access. |
| Library capacity | Compare your existing photo and video library with local capacity and cloud storage allowance; check whether photo copies retain the quality you need. | A growing collection of original photos and videos needs room for future copies as well as today's files; for about 20% of consumers, handling a large library is the primary concern. |
| Phone coverage | Confirm the selected photo folders and backup status, then check whether the workflow restores files or device data. | If my phone holds the newest family pictures, I want to know which ones have been copied and what I could restore to a replacement; about 13% of consumers put phone coverage first. |
| Account access | Enable 2-step verification and keep a recovery method that does not rely solely on the phone being backed up. | A cloud copy is little use to me if I cannot sign in after losing my phone; about 13% of consumers primarily need a recoverable, protected account. |
Synchronised changes and deletions can affect another location. Microsoft documents version and deleted-file recovery for OneDrive, but the available options depend on the account and feature.
Check the service's recovery rules, then keep another separate copy of files you cannot replace.
A connected drive may be affected by an incident involving the computer or local network. The National Cyber Security Centre recommends keeping backup copies separate.
Connect the drive for scheduled backups, disconnect it afterwards and maintain an off-site copy of important files.
Synology warns that drive failure or a RAID problem can still cause data loss. Drive redundancy does not replace a copy at another destination.
Back up the NAS to an external or cloud destination and test a restoration.
A NAS also brings setup, maintenance and drive-replacement responsibilities.
Loss of account access can prevent you from retrieving a cloud copy. The National Cyber Security Centre advises strong account credentials and 2-step verification.
Keep a secure recovery method available independently of the phone you are backing up.
Apple's iCloud services are relevant when photos and device restoration centre on an iPhone, iPad or Mac.
OneDrive is relevant to people keeping active documents available across Windows computers and mobile devices.
Google Photos provides a phone-photo workflow for Android and iPhone users who want uploads to a Google Account.
Dropbox Backup is relevant to selected computer or external-drive folders that you may need to restore to another computer.
Synology NAS products are relevant to households needing shared local storage and managed backups.
These portable hard drives, SSDs and phone storage provide local-copy options for computer files, larger photo libraries or selected phone media. Pair a local copy with a separate off-site copy when the files would be difficult to replace.

Consider this 5TB portable hard drive for a local copy of computer files or a large photo library. It is the for Mac variant; confirm your computer's connection and file-system requirements, particularly if you intend to use it with Windows. Check the backup schedule and restoration workflow you plan to use.

This portable hard drive is a local storage option for a substantial collection of photos and documents. Check file-system compatibility before using the 4TB drive with your computer, especially if you use a Mac, and plan how you will make and restore copies. The drive alone does not provide off-site protection.

This portable SSD offers a local destination for files you move between compatible devices. Its stated capacity is 1TB and its connection is USB 3.2 Gen 2; check that your library fits and that your devices have the connection you need. Keep another copy separately if these files would be difficult to replace.

This 1TB USB 3.2 Gen 2 SSD is a portable local-storage option for files used with compatible computers or phones. The named Magnetic Set is associated with iPhone 15/16 use; check attachment conditions and your device's file-transfer workflow. Confirm how copies will be made and restored before depending on it for phone photos.

This USB-C phone drive is a local-copy option for selected photos and videos. Check that your particular phone and intended folders work with the app, that 256GB is sufficient, and that a backup has completed. A photo-copy workflow should not be assumed to restore an entire phone.
No. Sync keeps files aligned for everyday access, whereas a backup is a separate copy intended for recovery. If you rely on a sync service such as OneDrive, check its version history, deletion behaviour and account-specific recovery periods, then keep an independent copy of irreplaceable files.
Use both local and off-site copies when losing the files would be difficult to remedy. A local drive gives you a copy close at hand, while an off-site copy addresses a different location being affected. The National Cyber Security Centre describes the 3-2-1 approach as at least three copies on two devices, with one off-site.
Check the photo service's backup status, intended account and selected folders, then try opening recent images from another signed-in device. Google Photos Help advises checking backup status when expected uploads do not appear.
Make a fresh backup, confirm that it completed and test retrieving representative files before removing data from the old device. If you need to rebuild an iPhone or iPad, check that you have an appropriate device backup: Apple says restoration can take hours or days depending on the amount of information.
Use a strong, unique sign-in method and enable 2-step verification. The National Cyber Security Centre says this makes account access harder for criminals; keep an alternative recovery method safely available in case the phone used to sign in is lost.
