For a household financial-record backup, choose a drive you can use regularly and move away from the main computer: a portable SSD suits a compact copy, while an external hard drive may suit a growing archive. Cloud backup can provide another location, and network-attached storage can serve several devices, but neither replaces a separate, recoverable copy. The National Cyber Security Centre warns that connected backups can be affected by ransomware; protect sensitive portable storage with encryption and check that you can restore your files.
If a portable copy holds tax documents, statements or identity information, consider how to protect it if the drive is lost. The Information Commissioner's Office describes encryption as a way to protect personal information stored on backup media.
A removable drive may suit someone who wants a straightforward extra copy without running network storage. HM Revenue & Customs says tax records can be kept digitally; the practical test for a backup is whether the household can find and read the files when needed.
Central storage can help organise copies from multiple computers, but it needs another backup destination. Synology notes that a network-attached storage device can still lose data through drive or RAID failure.
For household financial records, start with the need that would determine your storage choice, then check whether the proposed setup also covers the other risks.
| Concern | What to check | Who this matters to |
|---|---|---|
| Protection and separation | Check how to encrypt portable storage and keep at least one copy disconnected or otherwise isolated. | If my tax and account documents are on a removable drive, I want them protected if it is lost and I do not want every copy exposed to the same computer incident. Around 36% of consumers would put protection and separation first. |
| Routine backup and restore | Check that the backup tool works with your computer and that you can restore a sample folder. | I need a routine I can keep up as new statements arrive, with files I can retrieve later. For around 29% of consumers, a repeatable backup and restore process would be the primary concern. |
| Capacity and connection | Size the current archive and allow for future copies; check the computer port and supplied cable. | Scans and older records are building up, so I need room for the archive and a drive that connects to my computer. Capacity and connection would lead the choice for around 21% of consumers. |
| Several household devices | Check device support, user access and the plan for backing up the central store elsewhere. | More than one household computer needs a dependable place for its files, and I am willing to manage that shared setup. Around 14% of consumers would prioritise multi-device management. |
The National Cyber Security Centre reports ransomware incidents affecting connected USB and network backup drives alongside the original files.
Keep another copy offline or otherwise isolated, and periodically restore a folder to check that the copy works.
Western Digital distinguishes password protection from hardware encryption and warns that some encrypted drives may not be readable outside their original enclosure.
Check the exact model's security and recovery arrangements, keep recovery information separately, and retain another backup copy.
Samsung says the T7 Shield's maximum transfer speeds require a compatible USB 3.2 Gen 2 host, cable and UASP support.
Check your computer's port and the cable before relying on the stated speed. For a mainly document-based archive, also weigh capacity and how easily you can maintain the backup routine.
A network-attached storage device remains a local system. Synology warns that RAID or drive failure can still cause data loss.
Use central storage only with a plan to maintain access controls and updates and to back it up to a distinct destination.
The T7 Shield portable SSD line is relevant when a compact, removable copy and connection speed matter.
Its portable-drive information is useful when comparing local archive storage with security features.
The Backup Plus Portable line is relevant to a growing local archive and a scheduled backup routine.
Its network-attached storage guidance is relevant when several devices need centralised backups.
These portable hard drives and SSDs are options for making a local copy of household records. Choose capacity and connection for your archive, then check how you will encrypt sensitive files and keep another copy separate.

This portable SSD suits a local copy you intend to move away from the main computer. It is a 1TB USB 3.2 Gen 2 model; Samsung says its maximum speeds depend on a compatible host, cable and UASP support. Check that 1TB covers your planned copies.

For a removable local copy, compare this drive's 2TB capacity with the size of your records and future backups. Check the file-system and driver requirements for your computer, along with how any backup software restores files.

This 4TB USB 3.0 portable drive is an option for a growing local archive. Check computer compatibility and any formatting requirements before use; if the records are sensitive, confirm how you will encrypt the backup.

This 1TB USB 3.2 Gen 2×2 SSD is a portable local-storage option if its connection suits your device. Check host support before relying on its stated maximum transfer speed, and confirm your encryption and backup routine for financial files.
Yes. HM Revenue & Customs says records can be kept on paper, digitally or in software; where Self Assessment rules apply, make sure the records remain accurate, complete and readable.
No, not as the only backup. The National Cyber Security Centre has reported ransomware affecting connected USB and network backup drives, so keep another copy offline or otherwise isolated and check that you can restore it.
Not necessarily. An off-site cloud copy separates records from the home computer, but the National Cyber Security Centre says cloud backups are not ransomware-resistant by default. Check account access and file recovery, and retain another separate copy for important records.
Encryption is worth considering when the drive holds personal information and could be lost or stolen. The Information Commissioner's Office describes encryption as protection for information on backup media; keep recovery information securely and separately from the drive.
No. Synology warns that RAID or drive failure can still cause data loss on a NAS. If you use one to collect household backups, arrange a copy at a distinct destination as well.
