Choose a backup arrangement before choosing a drive: keep a recoverable copy separate from the computer or account holding your working files. A portable drive can serve one computer and be stored elsewhere after use; shared home storage can bring several devices together, but the appliance needs its own external backup. Check the capacity, device format and restore method before buying.
If your photos and documents are mainly on one computer, decide whether you need copies of selected files or a broader computer backup. Microsoft Support says Windows File History saves earlier versions of files; Apple Support describes Time Machine backups to external storage for Macs.
When files are spread across computers, phones and accounts, a shared home destination can help bring copies together. Keep another copy outside that destination: Synology says BeeStation’s internal restore points do not replace a full backup.
A portable drive can be disconnected after a backup and kept apart from the main computer. Choose its capacity for the files you intend to protect, then plan when you will update and restore-test that separate copy.
Start with what you need to recover and where another copy will live; then match the storage and backup software to your devices.
| Priority | What to check | Your needs |
|---|---|---|
| Separate copies | Decide whether a portable drive can be disconnected and stored elsewhere, or whether cloud storage and a local copy fit your routine. For shared home storage, arrange a backup outside the appliance. The National Cyber Security Centre describes the 3-2-1 approach as at least three copies on two devices, with one off-site. | I want to recover my records even if the computer, account or one storage device is unavailable. |
| File history | Check which files the backup tool covers, how earlier versions are restored and how long they remain available. Microsoft Support says OneDrive sync passes file changes and deletions between the computer and cloud; Windows File History can save earlier file versions to external or network storage. | If I change or delete a photo by mistake, I want a way to retrieve an earlier copy—not just another view of the synchronised folder. |
| Capacity and routine | Add up the files or devices you will protect and allow room for new files and retained backups. Apple Support recommends a Time Machine disk with at least twice the Mac’s storage capacity. Check how backups will run and when you will test a restore. | My photo library may grow, and I need a backup routine I can keep up rather than a drive that only holds today’s files. |
| Devices and format | Check the computer port, supplied cable, file system and intended backup software. Apple Support identifies APFS or APFS Encrypted as preferred for Time Machine and says it cannot back up to a Windows-formatted disk. Samsung says the T7’s stated maximum USB 3.2 Gen 2 speeds require a compatible host, cable and UASP. | I need the drive to work with my actual computer and backup tool; if I move files between devices, I also need to plan the format. |
| Access control | For a portable or shared copy, check available encryption, passwords and user permissions, and keep the information needed to restore encrypted files. Decide who can change or delete backups on shared storage. | Other people may use our home storage, or I may carry a drive containing personal records. |
Microsoft Support says OneDrive synchronises changes and deletions between the computer and its website. Its version history offers a recovery route for supported files, but that is different from keeping an independent copy.
Keep another copy outside the same synchronised folder and check that you can restore files from it.
Copies kept together may not provide the separation you need if that location is affected. The National Cyber Security Centre’s 3-2-1 approach includes an off-site copy.
After updating a portable backup, disconnect it where practical and store a completed copy separately.
A compatible-looking connector does not establish that the drive has the right format for your backup tool. Apple Support says Time Machine cannot back up to a Windows-formatted disk; Samsung’s quoted T7 maximum speeds also depend on the host, cable and UASP.
Identify your computer ports, backup software and required disk format before choosing a drive. Move any existing files to a safe location before reformatting.
Synology says BeeStation restore points are not a replacement for full backups. They remain part of the appliance’s recovery arrangement rather than a separate external copy.
Set up a backup of the appliance to a separate supported location and practise restoring a file.
The Portable SSD T7 range illustrates a small drive for moving a local copy between places.
The WD Elements Portable 4TB listing is an example of a portable hard drive for a sizeable local file copy.
BeeStation 4TB represents a shared home-storage route rather than a drive attached to one computer.
These portable hard drives and SSDs are options for making a local copy that you can disconnect and store separately. Choose one for your backup scope and devices, then plan the other independent copy your arrangement needs.

A portable local destination for a large personal file library. The product information specifies USB-C, scheduled backup software and password-activated 256-bit AES hardware encryption. For Mac backup, check the required format and software: the product information describes Mac use with a downloadable NTFS driver. If you need earlier file versions, confirm how the software restores them.
No image available
A carryable local copy for a photo or document library. The product information specifies USB 3.2 Gen 2, AES 256-bit hardware encryption and USB-C-to-C and USB-C-to-A cables. Its stated speeds of up to 1,050 MB/s read and 1,000 MB/s write depend on a compatible host and connection; choose backup software and formatting for the restore method you need.
No image available
A portable hard drive for a sizeable local archive. Its product information specifies USB 3.2 Gen 1, scheduled backup utilities, password protection and 256-bit AES hardware encryption. For Mac use, check the format required by your chosen backup tool; the product information describes access using an NTFS compatibility driver. Check the utility’s restore options if earlier versions matter.

A portable SSD to consider for selected files if 1TB accommodates your backup scope and retained copies. The product information specifies USB-C, USB 3.2 Gen 2 and an IP65 rating; observe its stated limits on water exposure rather than treating it as suitable for submersion. Check the format and backup software needed by the devices you intend to use.

A portable local destination for photos, videos and documents. The Joybuy listing specifies 4TB and USB 3.2 Gen 1/USB 3.0 connectivity. Check the backup scheduling and file-history features of the software you intend to use; the product information says Mac or other operating-system use may require reformatting.
Not by itself. Microsoft Support says OneDrive passes changes and deletions between a synced computer folder and its website; its version history can restore earlier versions of supported files, with a stated 30-day retention period. The National Cyber Security Centre advises keeping an independent copy in another safe place or service rather than relying only on provider recovery features.
Base capacity on everything you intend to protect, with room for new files and retained backups. For Time Machine specifically, Apple Support recommends a disk with at least twice the Mac’s storage capacity; that is not a universal requirement for other backup methods.
It needs careful formatting. Apple Support says Time Machine cannot back up to a Windows-formatted disk and identifies APFS or APFS Encrypted as preferred for its backup disk. Plan separate storage or suitable separate volumes for the intended uses, and copy existing files elsewhere before reformatting a drive.
No. Synology says BeeStation’s internal restore points are not a replacement for full backups and recommends backing up its data to an external location. Include that additional copy when planning a shared household destination.
Update it often enough for the amount of recent files you could afford to lose, and periodically restore a file or folder to check the process. UK government preparedness guidance recommends understanding how to restore your data and practising occasionally.
