Keep a recoverable local copy of household financial records and a separate off-site copy rather than relying on one drive or cloud account. An external hard drive suits a larger home archive; a portable SSD or encrypted USB drive suits files you need to carry, while cloud storage offers off-site access when paired with an independent local backup. Whichever arrangement you choose, protect access and test that you can restore a file.
If scans and statements are currently on one computer, keep copies elsewhere so a computer failure, deletion or loss does not leave you without them. The National Cyber Security Centre describes a backup as a copy kept in a separate safe location.
If a drive travels with you, consider how its contents would be protected if it were lost or stolen. The Information Commissioner's Office identifies encryption as a way to protect stored information from unauthorised access in that situation.
Cloud storage can provide an off-site copy you can reach without your main computer. Keep a separately managed local backup too, and protect the cloud account with two-step verification, as recommended by the National Cyber Security Centre.
Decide what must remain recoverable first, then choose where to keep each copy and how to protect access to it.
Choose it when: You want a local destination for a larger archive of scans, statements and other files.
Plan for: Disconnecting it between backup sessions and keeping another copy elsewhere; a connected drive can be affected by the same incident as the computer, according to the National Cyber Security Centre.
Choose it when: You expect to carry the local copy or transfer files frequently.
Check: The exact model's password setup and your computer's connection; Samsung says its advertised T7 speeds depend on compatible host hardware and cables.
Choose it when: You need a portable, separately stored copy of selected sensitive documents.
Plan for: Credential recovery and a second copy; Kingston says some IronKey security controls can restrict access after repeated incorrect attempts.
Choose it when: You need an off-site copy and access from another device.
Plan for: Account recovery, two-step verification and a separate local copy rather than depending on one online account.
| Concern | What to check | Who this matters to |
|---|---|---|
| Recovering files | Check capacity for the folders you intend to protect, and restore a test file. Disconnect a local backup drive outside backup sessions. | If my computer fails or files are deleted, I need to retrieve my records from a separate copy. About 36% of consumers put recovery first. |
| Protecting a lost drive | Check the exact model's encryption setup, password recovery options and behaviour after failed attempts. | When I carry sensitive records, I want to limit access if the device is lost or stolen. For about 29% of consumers, that protection is the primary concern. |
| Off-site access | Check which folders are stored, how account recovery works and whether two-step verification is available; maintain a separate local copy. | If I cannot use my main computer, I need to reach my documents from another device. That off-site access comes first for about 21% of consumers. |
| Selected portable files | Check whether the selected folders fit, which connector your computer needs and how you will open the files later. | I only need to store a small set of key documents away from the computer, not carry my whole archive. About 14% of consumers prioritise that controlled portable copy. |
A permanently connected copy may be affected alongside the computer during a ransomware incident, as the National Cyber Security Centre warns.
Set a backup routine, disconnect the drive when the backup is finished and keep another independent copy in a separate location.
Access to an online copy depends on the account, and a cloud location should not be assumed to withstand every destructive or account-access event.
Enable two-step verification, establish how to recover the account and retain a separately managed local copy.
Encryption helps protect confidentiality, but it cannot recover files if you lose access to the drive. Kingston describes lockout or credential-erasure controls for some encrypted models.
Check the chosen model's recovery procedure, store the necessary credentials securely and test a second backup.
A folder of selected PDFs, a growing scan archive and a whole-computer backup call for different amounts of space. A transfer-speed claim also depends on the connection used.
List the folders and file types, allow room for future scans, and check the exact device's connector and computer compatibility.
Its T7 portable SSD line is relevant when a compact local copy will be moved or updated frequently.
The Vault Privacy 50 line is an encrypted USB option for a portable copy of selected documents.
An off-site storage route for access from another device, paired with a separately managed local backup.
These local-storage options cover portable SSDs, external hard drives and a USB drive for selected financial documents. Pair a suitable local copy with a separately stored copy, and check that you can restore the files you need.

A portable local copy for records you expect to move or update frequently. This 2TB USB Type-C 3.2 Gen 2 model has optional password protection described by Samsung; set it up before storing sensitive files. Keep another copy separately and test restoration.
No image available
A portable SSD option when the local copy may travel. This 1TB USB Type-C 3.2 Gen 2 variant is in Samsung's T7 Shield line; confirm the password setup and compatibility with your computer before relying on it for sensitive records. Keep a second copy elsewhere.

A 5TB external hard drive for a larger local document archive. This is the Mac-oriented variant; if you will use Windows, confirm the file-system setup needed for your computer. Disconnect the backup between sessions and retain a copy in another location.
No image available
A 4TB USB 3.0 local drive for keeping an archive separate from the computer between backup sessions. If the drive may be lost or carried, check the exact model's encryption options; also confirm compatibility with your computer. Test file restoration and keep another separate copy.
No image available
A removable copy for selected documents rather than an archive whose size you have not checked. The product name specifies USB-A and Type-C connections and fingerprint encryption; confirm how access and recovery work after failed attempts before storing sensitive files. Keep another tested backup.
Do not rely on one drive as the only place your records can be recovered. The National Cyber Security Centre describes a backup as a copy stored separately and advises using both online storage and a storage device for additional protection. Check that you can restore a file from each copy.
Disconnect it when a backup is not running. The National Cyber Security Centre warns that ransomware can affect connected USB and network backup drives, so a drive left plugged in may not provide the separation you need.
Encryption can reduce the risk of unauthorised access to files on a lost or stolen device, according to the Information Commissioner's Office. It does not recover files or forgotten credentials: check the chosen drive's access rules and keep another copy.
Protect the cloud account as well as maintaining a separate local backup. Enable two-step verification where available, establish how you would recover account access and confirm which folders your storage arrangement actually copies.
The Information Commissioner's Office says UK GDPR does not apply to processing carried out purely for personal or household activities. That distinction does not cover business or other non-household processing, and encryption can still help protect sensitive files on a portable device that is lost or stolen.
