What should you check before choosing?
Start with the files and recovery situations that matter, then choose local and off-site destinations that can cover them.
| Priority | What to check | Your needs |
| Earlier versions |
Check whether individual files can be restored; which folders are included; and how long deleted or changed versions remain available. |
I want to recover an overwritten document or deleted photo, not just the latest synchronised copy. Microsoft documents previous-version restore in File History; retention for a cloud service needs checking separately. |
| Separate copies |
Identify which copy remains available if the PC and an attached drive are affected together. Plan when to update and disconnect an offline drive. |
If something happens at home, I need a copy elsewhere. The National Cyber Security Centre describes a three-copy approach across two devices, with one copy off-site. |
| Capacity and upload |
Total the folders and external archives to be protected; allow for growth; check the drive or cloud allowance and whether the initial upload is practical. |
Our photos and videos need room to grow, and a large first upload may not suit our connection. Microsoft notes that external or network storage may suit large files or numerous files. |
| File access and privacy |
Review cloud sharing and account controls; check the exact drive’s encryption options and how access is recovered if a password is lost. |
I want family documents accessible to the right people without leaving a portable copy unprotected if it goes missing. |
| Recovery scope |
Confirm which personal folders are copied, whether earlier versions can be restored, and whether a separate Windows recovery procedure is needed. |
Restoring a photo is different from getting Windows running after replacing a drive. Microsoft describes File History, Windows Backup and Recovery Drive as tools with different purposes. |
Relevant brands and services
These examples illustrate different backup routes; features should be checked for the particular product or service being considered.
Seagate
External HDDs for households planning a large local file copy.
- Seagate’s UK range includes external hard drives, and the company says its Backup Plus portable drive works with Windows built-in backup tools.
- Capacity, connection and backup features need checking on the exact drive.
Samsung
Portable SSDs for a local copy that will be moved or used for frequent transfers.
- Samsung lists AES 256-bit password security and up to 1,050 MB/s read and 1,000 MB/s write for its Portable SSD T7; transfer performance depends on the connected computer.
- Those T7 details should not be assumed for every Samsung SSD or capacity variant.
Synology
NAS hardware and backup software for households managing shared local storage.
- Synology says Hyper Backup supports multiple destinations and backup versions.
- Synology states that RAID and Synology Hybrid RAID are not backups; a separate destination is still needed.
Microsoft
Windows file-backup tools and OneDrive folder synchronisation.
- Microsoft documents recurring File History copies to an external drive or network location and selected-folder synchronisation through Windows Backup.
- Check the folders, account, storage allowance and restore method for the tool you use; the Windows tools do not all cover the same recovery task.
Backblaze
A dedicated cloud computer-backup route rather than just a synchronised folder.
- Backblaze describes its computer backup as maintaining version history; its help guidance states a default history of 30 days.
- Check current retention, device eligibility and restoration options before relying on the service for a particular file.
External drives for local backups
These Joybuy drives offer local storage for household files. Each would need a suitable backup routine, and a drive kept at home does not by itself provide an off-site copy.

Frequently asked questions
Is a cloud-sync folder enough for backup?
Do not assume it is. Microsoft says Windows Backup synchronises selected folders to OneDrive, so check which files are included, whether deleted or changed versions can be restored, and how long they remain available. Keep an independent copy for files you cannot replace.
How much backup storage do we need?
Add up every folder and archive you intend to protect, including photos and videos outside the usual PC folders, then allow room for growth and retained versions. Microsoft notes that external or network storage may suit large files or numerous files; check that any chosen cloud allowance also covers the intended set.
Should I use an HDD or an SSD for a local backup?
For a large archive that will stay in one place, compare HDD capacity with the size of your files. If you will carry the drive or transfer large files frequently, compare portable SSD capacity, connections and model-specific features instead. Neither type becomes an off-site backup while it stays beside the PC.
Does a two-drive NAS remove the need for backup?
No. Synology explicitly states that RAID and Synology Hybrid RAID are not backup solutions. A NAS used for household files still needs another backup destination and a restore procedure you can use.
How should I protect a drive containing family files?
Keep at least one recoverable copy separate from the PC, and avoid leaving every backup drive connected continuously. The National Cyber Security Centre recommends an off-site copy and warns that connected backups can be affected in ransomware incidents. For a portable drive holding sensitive documents, check its encryption and password-recovery options before use.
