Households with large photo and video libraries
Check how much space your selected files use and allow for growth. A higher-capacity portable HDD may suit a local archive backed up mainly at home, but keep another copy separately.
Who needs which backup?
Laptop users who carry backups between locations
Check the laptop’s port and cable before choosing a drive for transfer speed. If physical protection matters, read any resistance claims for the exact model and keep another copy of important files.
Households using Apple, Windows and Android devices
Check what each desktop and phone backup workflow actually includes. A drive connected to a computer does not, by itself, establish that phone data is being backed up.
What should you check before choosing?
Start with the files and devices you need to protect, then choose where each separate copy will live and how you will keep it up to date.
| Priority | What to check | Your needs |
|---|---|---|
| Capacity | Measure the files selected for backup and allow for growth. For Time Machine, Apple recommends a disk with at least twice the Mac’s storage capacity. | My photos, videos and documents need to fit, with room for future backups. |
| Separate copies | Decide whether you need a removable local copy, an off-device cloud copy or both. The National Cyber Security Centre advises disconnecting removable media when it is not in use. | If my computer is lost, damaged or affected by malware, I want a copy I can still access. |
| Carrying the drive | Check its size, connection and exact-model resistance claims. Samsung describes the T7 Shield’s IP65 and drop results as controlled-test claims; related damage is excluded from its stated warranty. | I’ll carry the backup between locations, so I need to weigh portability without treating a resistance rating as a guarantee against data loss. |
| Cloud limits | Check the allowance, renewal terms and files included. Google says Photos, Drive and Gmail share account storage; Microsoft says cancelling Microsoft 365 Basic reduces its cloud allowance from 100 GB to 5 GB. | I want automatic uploads to continue as my collection grows, without assuming a photo service covers every computer file. |
| Device setup | Check the required port, file system, backup software and encryption password. Microsoft’s File History uses an external drive or network location; folders outside its covered libraries need adding. | Our computers and phones use different backup methods, and I need to know which folders and devices each method protects. |
Backup mistakes to avoid
-
Choosing capacity from the computer’s free space
Free space does not tell you how large the selected photo library and documents are or how much room future backups need. Apple recommends a Time Machine disk with at least twice the Mac’s storage capacity.
Measure the files you intend to protect, allow for growth and apply the guidance for your backup software.
-
Leaving the only external backup connected
A permanently connected drive may not remain a separately recoverable copy when the computer is affected by a loss event. The National Cyber Security Centre advises disconnecting removable media when it is not in use.
Keep a separate copy, reconnect the drive for scheduled backups and check that a backup completed before disconnecting it.
-
Choosing an SSD by its quoted speed alone
Samsung says the T7 Shield’s stated maximum transfer speeds require a compatible USB 3.2 Gen 2 host, cable and UASP mode.
Check the computer’s port and the cable you will use before making transfer speed the deciding factor.
-
Assuming cloud-photo backup covers everything
Google account storage is shared across Photos, Drive and Gmail, while photo uploads have service conditions. A photo-backup setting does not establish that every document or device backup is included.
Check the files actually uploaded, the available allowance and what happens to uploads or syncing if your plan changes.
A paid storage plan can become an ongoing commitment when the included allowance is insufficient.
Relevant brands and backup tools
Samsung
The T7 Shield is a portable SSD option for a backup drive that travels. Samsung UK lists the 1 TB MU-PE1T0S model with USB 3.2 Gen 2.
- Samsung states sequential speeds of up to 1,050/1,000 MB/s for this model under compatible connection conditions.
- Its IP65 and 3-metre drop claims come from controlled tests; Samsung says related liquid, dust and drop damage is not covered by its stated warranty.
Seagate
Seagate’s One Touch portable HDD range is relevant to a local household archive. Seagate UK lists 2 TB and 4 TB versions.
- Seagate lists USB-C connectivity, hardware encryption and backup tools for the range.
- Confirm the exact model, capacity, connection and setup instructions before choosing a drive.
Apple
Apple’s Time Machine and iPhone or iPad backup instructions matter when a household combines a Mac backup disk with phone backups.
- Apple recommends a Time Machine disk with at least twice the Mac’s storage capacity.
- iCloud and computer backups can cover different content. Keep the password for an encrypted local iPhone or iPad backup: Apple says it cannot be recovered.
Microsoft
File History and OneDrive are relevant to Windows households deciding how to keep local and cloud copies.
- Microsoft says File History can make regular backups to an external drive or network location.
- Check that the folders you need are covered. Microsoft 365 Basic storage is shared across OneDrive and Outlook, and the allowance changes if the subscription ends.
Google Backup and Google Photos are relevant to Android and phone-photo workflows alongside computer backups.
- Google provides settings for automatic Android backup and photo or video uploads.
- Account storage is shared across Google products. Check upload conditions and the content included rather than assuming all computer and phone files are covered.

Backup questions answered
How large should a Time Machine backup drive be?
Apple recommends a disk with at least twice the Mac’s storage capacity: its example pairs a 1 TB Mac with a 2 TB backup disk. That is Time Machine guidance, not a universal capacity rule for every backup method.
Can Windows back up to an external drive without separate software?
Yes. Microsoft says File History makes regular copies of covered Windows libraries to an external drive or network location. Add folders outside those libraries if you want File History to include them.
Will an external drive automatically back up my phone?
Not by itself. Apple supports iPhone and iPad backups through iCloud or a computer, while Google provides Android and photo-backup settings. Check the supported workflow and included data for your phone before relying on a computer’s external drive.
Should I encrypt a household backup drive?
Consider encryption if someone else could access a lost drive, and keep the restoration password securely. Apple says an encrypted local iPhone or iPad backup password cannot be recovered; check the setup instructions for the exact drive or backup method you use.
Does an external backup drive need to stay connected?
No. The National Cyber Security Centre advises disconnecting removable media when it is not in use. If you use scheduled local backups, reconnect the drive regularly and confirm each backup has completed before disconnecting it.
