Use both a local drive and an off-site copy when losing photos or work records would cause serious disruption: a disconnected drive offers a separate local copy, while cloud storage can remain available if the device or drive is lost. If access across devices matters most, consider cloud sync, but check its deletion and version-history windows; for a dedicated backup service, check how long earlier files remain recoverable.
If invoices, client documents or project files are difficult to recreate, focus on whether you can restore an earlier version or a complete copy. Check how long the chosen service retains changed and deleted files, and keep a separate copy where a single failure would disrupt your work.
Cloud sync can keep current photos and documents accessible on a phone, laptop or tablet. Because changes can sync too, check sharing permissions and recovery windows before treating the synced folder as your only copy.
An external drive can provide a local backup without repeatedly uploading a large collection. Check its capacity and connection against the computer and backup software, then plan where to keep the drive when it is disconnected.
Decide whether your priority is recovering files, reaching current files from other devices, or making large local backups practical. You can combine routes when one copy cannot meet all three needs.
Choose it when: A large local library or unreliable internet makes a drive a practical place for a separate copy.
Trade-off: A drive kept with the computer does not provide an off-site copy; disconnect it between backups to limit exposure to incidents affecting connected storage.
Choose it when: An off-site copy and recovery after computer loss matter more than access to a shared, current folder.
Trade-off: Restoring an older file depends on the service’s retention setting, account access and an internet connection.
Choose it when: You chiefly need current files on more than one computer or phone.
Trade-off: The Information Commissioner’s Office explains that changes to files in a cloud folder are copied across; sync alone is not an unchanged backup.
Choose them when: Losing irreplaceable photos or work records would make both a local restore and an off-site copy worthwhile.
Trade-off: You must maintain two routes, including the drive’s backup routine and secure access to the cloud account. The National Cyber Security Centre advises considering both online and external-device backups.
| Concern | What to check | Who this matters to |
|---|---|---|
| Recovering lost or changed files | Check deletion and version-history windows, and try restoring a small file before relying on the backup. | If I cannot recreate a work record or family photo, I need a copy that remains recoverable after deletion or device failure. Roughly 33% of consumers would make recovery their primary concern. |
| Access across devices | Check which folders sync, who can access shared files, and how to undo an unwanted change. | When I move between a phone and computer, I want my current documents available on both without losing control of edits. Around 27% of consumers would put multi-device access first. |
| Local capacity and compatibility | Compare the files you will protect with drive capacity, then check the computer port and backup-software requirements. | For a large photo or project library, I need a local backup that fits the files and works with my computer. About 27% of consumers would prioritise that practical fit. |
| File and account security | Check sharing and account-recovery controls, and consider encryption for a drive carrying sensitive files. | If a portable drive is lost or my cloud account becomes inaccessible, I need to protect both the files and my route back to them. Roughly 13% of consumers would make security and account control their main concern. |
An unwanted edit or deletion can be copied across devices. Recovery then depends on whether a previous version or deleted file is still retained.
For files you cannot recreate, keep a separate copy and check that you can restore an earlier version.
The National Cyber Security Centre warns that incidents such as ransomware can affect connected backup storage as well as the main computer.
Disconnect and store the drive securely between backups, and keep an off-site copy of important files.
Samsung says the maximum transfer rates specified for its Portable SSD T7 2TB require a USB 3.2 Gen 2 host, a compatible cable and UASP. The operating system may also require reformatting.
Check your computer’s port, the available cables and the file format needed by every device that will use the drive.
A cloud copy is difficult to use if you cannot regain access to its account. Google says changes to account recovery information can take up to seven days to take effect.
Set up recovery methods in advance and store any backup codes securely away from your main device.
The Portable SSD T7 2TB is one model to consider for frequent local backups and large-file transfers.
Cloud storage and sync may suit people already using Microsoft accounts across their devices.
Cloud files may suit people using Google accounts who want access from more than one device.
A computer-focused cloud-backup option for people who prioritise restoring data files rather than working from a shared cloud folder.
These drives are choices for keeping a separate local copy of photos or work files. Check capacity and connections against your backup plan; add an off-site copy if losing the drive and main device together would leave you without the files.

Consider this portable local copy if your selected files fit within 1 TB. The title specifies USB 3.2 Gen 2; check your computer’s connection and backup setup before relying on it.

The 2 TB capacity may suit a larger selected backup set, provided you check how much space your files and retained versions need. Its title specifies USB Type-C and USB 3.2 Gen 2; confirm the connection and format needed for your devices.

This 2 TB portable hard drive is a local-copy option for a collection that fits within its capacity. Check its connection and the file-system setup required by each computer you plan to use.

The 5 TB capacity is relevant if a larger local library needs backing up. Because this is the for Mac variant, check the file format and software setup before planning to use the same drive with Windows; also confirm the applicable warranty term before purchase.

Consider this 1 TB local-copy option if you also want to check a phone-based file workflow. The title specifies USB 3.2 Gen 2x2, IP65 and MagSafe support, while its ProRes claim names iPhone 15/16 Pro models; confirm your exact device and connection before relying on that recording use. Check protection options separately if the drive will hold sensitive files.
Not on its own if you need an independent copy that remains unchanged after an accidental edit or deletion. The Information Commissioner’s Office explains that cloud-folder changes are copied across; check version recovery and keep a separate backup for files you cannot recreate.
It depends on the service, plan and type of recovery. Google Drive Help says deleted files remain in Trash for 30 days; Microsoft Support gives 30 days for personal OneDrive deletion recovery and file version history. Dropbox Help describes 30-day default version history for Dropbox Plus, with a one-year add-on, while Backblaze Help describes 30 days by default and selectable longer version-history options. Check the terms for your plan before relying on a window.
Choose capacity around the files and versions you intend to keep, rather than the drive’s headline size alone. For Time Machine specifically, Apple Support recommends a backup disk with at least twice the Mac’s storage capacity; that recommendation is not a universal sizing rule for other backup setups.
If the records contain personal data processed for your work, consider the security of both the backup and the way you regain access to it. The Information Commissioner’s Office says UK GDPR requires appropriate technical and organisational measures for processing personal data, and advises considering encryption where appropriate; it does not prescribe one backup product for every situation.
Set up a strong, unique password, an available second factor and account-recovery methods before you need to restore files. Google Account Help documents single-use backup codes for times when the usual second step is unavailable; store any codes securely away from your main device.
