Home-library backup planners
If your household photos and documents are kept on one computer, you need a separate copy that you update routinely, not just an occasional move of files.
Who needs a separate backup?
Portable backup users
If you carry a backup between places, the drive’s size, connector, transfer time and handling conditions become important parts of the choice.
Single-location risk reducers
If an incident at home could affect both your computer and its external drive, consider an additional copy kept elsewhere, alongside your local backup.
What matters when choosing storage?
Start with the files you intend to protect, then choose a drive you can connect and update regularly. Decide separately whether your backup also needs protection from an incident affecting everything kept at home.
External hard drive
Consider it when: Your photo and document library stays mainly at home and you want a dedicated removable backup disk.
Keep in mind: Check that the chosen capacity, connection and backup routine work for your files and computer.
Portable SSD
Consider it when: You carry the backup often or regularly transfer a large photo library.
Keep in mind: Quoted peak speeds depend on the host connection and cable; portability does not replace a second copy.
USB flash drive
Consider it when: Your selected files fit comfortably and a very small removable device suits your routine.
Keep in mind: Check the exact model’s usable capacity, connector and write behaviour before relying on it for repeated backups.
| Concern | What to check | Who this matters to |
|---|---|---|
| Capacity | Measure the files you will back up and allow room for additions. For Time Machine, Apple recommends a backup device with at least twice the Mac’s storage capacity. | If my photo and document collection keeps growing, I need room for the files I want to protect and future additions. Around 27% of consumers put capacity first. |
| Portability and transfers | Check your computer’s port, the required cable and the exact drive’s speed conditions. Samsung says its T7 Shield’s quoted maximum speeds require a compatible USB 3.2 Gen 2 host and cable, with UASP enabled. | If I carry my backup between places, I want updates to fit the time I have and the drive to be practical to take along. Roughly 20% of consumers prioritise portability and transfer time. |
| Backup routine | Check that your chosen software includes the relevant folders, runs when the drive is available and lets you restore a sample file. | When I might forget manual copies, I need a routine that keeps a separate copy current. Around 27% of consumers make a repeatable backup their primary concern. |
| Separate-location protection | If one incident could affect your computer and local drive, plan another copy elsewhere and check how you would restore it. The National Cyber Security Centre also advises keeping at least one backup offline. | If a loss at home could affect both devices, I need another copy beyond the local drive. Roughly 26% of consumers put separation from a shared incident first. |
Backup mistakes to avoid
-
Mistaking a file move for a maintained backup
Deleting the originals after a transfer can leave just one copy. A one-time copy can also become outdated as you add new photos and documents.
Keep the originals, set a repeatable backup routine and test that you can restore a sample photo and document.
-
Leaving the only backup beside the computer
The National Cyber Security Centre reports incidents in which ransomware affected connected USB and network backup drives. A local drive can also be caught in an incident affecting the computer’s location.
When those risks matter, keep an additional copy offline or in a separately managed location, and check that you can restore it.
-
Choosing an SSD from its peak speed alone
A quoted maximum may depend on a USB connection and cable that your computer does not have. Samsung specifies those conditions for the T7 Shield’s maximum transfer speeds.
Check the computer port, cable and exact SSD model against the stated speed conditions before deciding whether faster transfers will help your routine.
-
Reformatting a drive without protecting its existing files
Apple says Time Machine cannot back up to a disk formatted for Windows and that reformatting the disk permanently removes its data.
Inspect the drive before setting up Time Machine. Copy any files you need to keep to another verified location before erasing or repartitioning it.
Brands relevant to backup setups
Seagate
Seagate’s Backup Plus Slim is a reference point for a portable hard drive with a scheduled-backup option.
- Seagate describes single-click and scheduled backups for the Backup Plus Slim.
- Check the exact drive, supplied connection and software support for your computer before choosing a backup routine.
Samsung
Samsung’s T7 Shield is relevant to buyers considering a portable SSD for frequently moved backups.
- Samsung UK states that the T7 Shield uses USB 3.2 Gen 2 and describes IP65 water and dust resistance and drop testing for the model.
- Samsung’s maximum speed figures require the specified host, cable and USB mode. Its resistance claims depend on test conditions and do not make the drive a complete backup plan.
Apple
Apple’s Time Machine guidance matters when an external drive is intended primarily as a Mac backup destination.
- Apple supports Time Machine backups to directly connected external USB or Thunderbolt storage and recommends at least twice the Mac’s storage capacity.
- Apple says a Windows-formatted disk must be reformatted before Time Machine can use it; reformatting permanently removes existing data.
Joybuy drives for local backups
These external hard drives and portable SSDs offer local storage for a separate copy of home photos and documents. Choose capacity against your own files, then check the connection and backup routine you intend to use; a local drive alone does not cover a loss affecting both it and your computer.

Questions about home backups
Can I delete photos from my computer after copying them to an external drive?
Keep the computer copy if the external drive is meant to be its backup. Confirm that the files copied and can be opened or restored; deleting the originals after a simple transfer would leave you relying on just the drive.
How large should a drive be for Time Machine?
Apple recommends a backup device with at least twice the Mac’s storage capacity for Time Machine. If you are manually copying only selected photos and documents instead, size the drive against those files and allow room for growth.
Can the same drive hold Windows files and a Mac Time Machine backup?
Check the drive’s formatting and your intended volume arrangement before using it for both. Apple says Time Machine cannot back up to a Windows-formatted disk, and reformatting a disk for Mac use permanently removes its existing data.
Does a backup drive have to stay plugged in?
It needs to be connected when its backup routine runs, but a removable drive need not remain connected continuously. The National Cyber Security Centre has reported ransomware affecting connected backup media and advises keeping at least one backup offline.
