For photos and files that would be difficult to replace, keep an accessible local copy and a separately recoverable backup; a synchronised folder alone may mirror unwanted changes. Choose the local storage that fits your library and devices, then check the backup’s version history, restore process and account access before relying on it.
If photos and documents must open without an internet connection, check where each file is actually stored. Microsoft Support explains that OneDrive Files On-Demand can show cloud files without keeping them on the device; choosing “Always keep on this device” makes those files available offline but uses local space.
If an older or deleted version matters as much as the current file, look for a separate backup with a retention period and a workable restore process. The National Cyber Security Centre describes a backup as a copy kept in a separate safe location; a service’s version-history terms determine which earlier files remain recoverable.
If a drive carrying personal files could be lost or stolen, assess encryption alongside capacity and connection type. Information Commissioner’s Office guidance also makes password strength relevant where an encryption method depends on the user’s password.
Decide what must remain accessible locally, then choose a separate destination from which you can restore important files. A desktop drive, portable drive or network-attached storage can serve the local side; a backup kept elsewhere, including a suitable cloud-backup service, addresses a different recovery need.
| Concern | What to check | Who this matters to |
|---|---|---|
| Recoverable versions | Check whether files are backed up separately or merely synchronised, how long earlier and deleted versions remain available, and how to restore them. | If I accidentally replace or delete photos, I need an earlier copy rather than another view of the current folder. Around 29% of consumers would put recoverable versions first. |
| Local access and growth | Measure the library, allow room for new files and confirm which folders will actually remain available offline. | When I need my whole library at home without downloading files on demand, local space and future growth drive my choice. Local access would come first for around 29% of consumers. |
| Capacity and connection fit | Check the required capacity, whether the drive will stay on a desk or travel, and the computer’s ports, cables and formatting requirements. | I want a drive I can connect and use where my files are needed, without choosing an awkward size or format. Around 24% of consumers would make that practical fit their primary concern. |
| Privacy and account access | Check the encryption and password-recovery arrangements for a carried drive, plus two-step verification and recovery methods for cloud accounts. | If I carry personal documents or keep a copy online, I need to protect access without losing my own way back in. Privacy and account access would lead the decision for around 18% of consumers. |
A sync service can mirror an unwanted deletion or change. IDrive distinguishes folder synchronisation from backup, while Backblaze documents version history for changed or deleted files.
Before relying on a service, check its version history, deletion-retention period, restore steps and coverage of any external drives you use.
Once a retention window expires, an older or deleted version may no longer be available to restore.
A growing library needs space for new files, while cloud files made available offline also occupy device storage. Microsoft Support notes this distinction for OneDrive Files On-Demand.
Measure the files you need to preserve, decide which must open offline and leave room for growth before choosing storage capacity.
Samsung says the T7’s stated maximum speeds require a USB 3.2 Gen 2 host, a compatible cable and UASP. A different connection may not deliver those maximum figures.
Check your computer’s port and the cable you will use before treating a rated transfer speed as a reason to choose a drive.
Encryption can protect files on a lost drive, but access to encrypted storage or a cloud backup also depends on credentials and recovery methods. The National Cyber Security Centre recommends two-step verification for important accounts.
Keep recovery information securely and enable two-step verification for the cloud account and its associated email account.
Losing an encryption key or account-recovery method can prevent you from opening the copy you kept.
Its Expansion desktop drive line illustrates desk-based local storage for a large archive.
Its portable T7 SSD line is relevant when a working library needs to move between compatible devices.
Its network-attached storage tools address a central household library and scheduled computer backups.
Its dedicated cloud-backup service is a route to an off-site copy rather than access through a synced folder alone.
Its computer-backup service is relevant when recovery of changed or deleted files is part of the decision.
These portable hard drives and SSDs offer ways to keep a local photo and file library. Choose capacity and connections for your devices, then arrange a separate backup destination for important files; a drive in this list is not itself an off-site copy.

Consider this portable external hard drive if you need a local copy and the listed 5TB capacity fits your library and expected growth.
Check connection and formatting requirements for every computer you plan to use, and confirm the backup software’s version-retention and restore options before relying on them.

Consider this portable external hard drive for a local photo and document copy if 2TB accommodates the files you intend to keep.
Check compatibility with your operating system and whether the backup arrangements you use retain earlier or deleted file versions.

Consider this portable SSD for a local copy of selected folders or a library that fits within its listed 1TB capacity.
Its name specifies a USB Type-C 3.2 Gen 2 connection; check your device’s port and the backup and restore arrangements you will use with the drive.

Consider this portable SSD for a local copy that fits within 1TB and may need to move between compatible devices.
The product name specifies USB 3.2 Gen 2 and rated read and write speeds of up to 1,050 MB/s and 1,000 MB/s respectively; check your connection and formatting needs rather than assuming those speeds with every device.

Consider this portable external hard drive for a larger local archive if its listed 4TB capacity leaves sufficient room for your files to grow.
Check the USB connection and any formatting requirements for your computer. Plan the encryption and versioned backup arrangements you need separately.
Not necessarily: synchronisation can mirror a deletion or unwanted change, while a separately recoverable backup needs a usable restore copy. IDrive distinguishes sync from backup; check any service’s version history, deletion retention and coverage of the folders or drives you need to protect.
Start with the size of the files you need to keep, then allow room for future additions and any backup versions stored on that destination. Also check where offline files will live: Microsoft Support explains that OneDrive files kept on a device use its local storage.
Choose by how you need to use the local copy: a desktop hard drive can hold a desk-based archive, a portable SSD suits files moved between compatible devices, and NAS can provide a central household library with scheduled backup tools. None automatically gives you a copy in another location, so arrange a separate backup for irreplaceable files.
It should keep them for long enough to match when you are likely to notice a problem and attempt a restore. Backblaze Help documents a default 30-day version history and longer options; check the retention setting and terms of the service you choose before depending on an older copy.
Encryption is worth considering when a drive holding personal information could be lost or stolen. Information Commissioner’s Office guidance describes encryption as protection for stored personal information; keep the password or key securely, because losing it can also prevent your own access.
