A useful backup is a separate copy you can restore, not simply more storage on your everyday device. Choose a removable drive for a local backup routine, a network-attached storage device (NAS) for shared household storage you are willing to manage, or cloud backup when an off-site copy matters; a portable SSD suits a library you need to carry. Whichever route you choose, check what is copied and test a restore before relying on it.
If your photos, videos and documents cannot be recreated, your priority is a second copy held apart from the device you use every day. The National Cyber Security Centre advises making regular backups and checking that you can restore them.
If files are spread across computers, look for a routine that does not depend on remembering to copy folders by hand. Microsoft Support describes backup of selected Windows folders through a Microsoft account; Apple Support lists compatible NAS devices as Time Machine destinations. Check which devices and folders your chosen setup actually covers.
If a portable backup contains personal documents, check encryption support on the exact drive and plan how you will keep its password safe. Western Digital warns that a forgotten password on a supported WD Security drive cannot be recovered and the drive must be erased.
Decide where the separate copy will live and how it will be updated before choosing capacity or a connection. Encryption can protect a compatible drive if it is lost, but it does not create another copy.
Consider it when: You regularly carry a photo or video library or transfer large files between compatible devices.
Bear in mind: Rated speeds depend on the host connection and cable, and a drive you carry can be lost.
Consider it when: You want a directly attached local copy of a growing household library and can connect the drive for regular backups.
Bear in mind: You need a routine for disconnecting or storing the copy separately; the drive alone is not off-site protection.
Consider it when: Several household devices need a shared network destination and you can manage its setup and updates.
Bear in mind: A NAS in your home needs another separate destination to protect against loss affecting the whole premises.
Consider it when: You want an off-site computer backup that can update automatically over an internet connection.
Bear in mind: Check which files are included, how restoration works and how long older or deleted versions remain available.
| Concern | What to check | Who this matters to |
|---|---|---|
| A separate, recoverable copy | Choose a destination apart from the main device; make a regular copy and test a restore. | If files cannot be recreated, I need to recover them after a device failure or accidental deletion, not just store them in another folder. About 37% of consumers would put separation and recoverability first. |
| Room for a growing library | Measure the files to be protected and allow room for new photos, videos and any backup history you want to keep. | As my photo and video archive grows, I want enough local room for future files and earlier versions. Roughly 27% of consumers would make capacity their primary concern. |
| Portability and transfers | Check the host connection and cable against the drive’s stated interface; consider where the drive will be stored between backups. | When I take a file library between locations, carrying the drive and moving large files matter to my choice. About 18% of consumers would prioritise portability and transfers. |
| Privacy if a drive is lost | Confirm encryption on the exact model, any setup software required and how you will retain access to its password. | If a portable backup goes missing, I want its personal files protected without losing access to my own copy. Approximately 18% of consumers would put protection of a lost drive first. |
Files held only on the main device, or on a drive that stays connected to it, may still be lost together. The National Cyber Security Centre advises against leaving an external backup device permanently connected and recommends checking that restoration works.
Make a separate copy, store a removable drive away from the computer between backup sessions, and restore a sample file or folder to check the routine.
A NAS can centralise household copies, but a loss affecting the premises could affect both the original devices and the NAS. Synology describes additional destinations for its Hyper Backup software; those destinations still have to be configured.
If files need protection beyond the home, add a separate removable or off-site destination rather than relying on the NAS alone.
Version retention varies by service and account settings. Backblaze states that its default version history is 30 days, with longer options available.
Before using a cloud service for long-term recovery, check its current retention terms, coverage of external drives and restore method.
Encryption support depends on the model and setup. Western Digital says a forgotten password on a supported WD Security drive cannot be recovered and the drive must be erased.
Confirm support for your exact drive, then keep the password or recovery information securely apart from the drive and main computer.
The T7 Shield line illustrates the portable-SSD route for a household that wants a compact drive for local copies.
Selected external drives support a directly attached backup with password-based hardware encryption.
Supported One Touch external drives offer a local route with Toolkit-guided backup features.
Its NAS software is relevant when a household wants shared network storage and configurable backup destinations.
Its computer-backup service represents the automatic, off-site cloud route.
These portable external-drive and SSD options can hold a local copy of household photos and files. Choose one alongside a routine for updating it, keeping it separate from the main device and testing restoration.

Consider this portable external hard drive for a local copy of a growing photo and document library. It has 2 TB of stated capacity; check that your planned backup software works with your computer, and test a restore. If you intend to use password protection, confirm the procedure for this exact variant before enabling it.

This is a portable local-storage option if you carry a large photo or video library. Its stated connections are USB Type-C and USB 3.2 Gen 2x2; check your computer and cable for compatibility, and decide how backups will run and be restored before relying on the drive.

Consider this 1 TB portable drive if you need to carry a local file copy between locations. It uses a USB Type-C, USB 3.2 Gen 2 connection. Check device compatibility and your backup workflow, then restore a sample file before depending on the copy.

This 2TB portable SSD is an option for carrying a local photo and file copy. Check the backup software and restore process you plan to use, as well as encryption support if the drive will hold sensitive files. Store the copy apart from your main device between backup sessions.
No: extra space or syncing alone does not establish that you have a separate, recoverable copy. For important files, the National Cyber Security Centre advises regular backups, checking restoration and not leaving an external backup device permanently connected.
Yes, if the destination is compatible. Apple Support lists directly connected external storage and NAS devices that support Time Machine over SMB or AFP; check the particular NAS before buying, as some third-party network disks do not support Time Machine.
Recovery depends on the provider’s version-retention settings. Backblaze states that its default version history is 30 days and offers longer options, so check the terms of your chosen service before treating it as an archive for older or deleted files.
