Households protecting irreplaceable memories
Family photos, videos and personal documents may be difficult to recreate. The National Cyber Security Centre advises considering both cloud and removable-media copies for irreplaceable photos and videos.
Who needs a separate copy?
People with large libraries who need local access
A substantial collection may need a local copy that can be opened without an internet connection or a cloud service’s current sync settings. Microsoft Support notes that OneDrive online-only files cannot be opened while the device is offline.
People moving files between devices
If photos and documents travel between a phone, Mac and Windows PC, check connectors as well as the drive’s file system. Apple identifies formats for Windows-compatible use, while SanDisk offers a dual-connector drive for selected USB-C and USB-A transfers.
What matters when choosing?
Decide whether the copy must remain accessible without internet, recover independently of a synced folder, or travel between devices. Then size the storage for the files you intend to keep.
Local drive
Choose it when: You need an offline-accessible copy of a large collection or regularly carry files between devices.
Trade-off: A drive kept in the same place as the originals does not provide a separately located copy; a connected drive can also be exposed during a malware incident, as the National Cyber Security Centre warns.
Cloud storage
Choose it when: Access across devices and a copy away from your local drive matter most.
Trade-off: Online-only files need a connection unless you make them available locally; synchronisation may also carry a deletion across devices.
Local and cloud copies
Choose it when: Irreplaceable files need both local access and a copy held separately.
Trade-off: You must maintain both copies, secure account access and periodically check that recent files can be restored.
| Concern | What to check | Who this matters to |
|---|---|---|
| Independent recovery | Check where separate copies are kept and whether you can restore a sample folder. Consider disconnecting a removable copy after updating it. | If family photos are lost from my main device or cloud account, I need another copy I can actually restore. Around 36% of consumers put independent recovery first. |
| Capacity for a growing library | Measure the current collection and allow room for growth; compare that need with the drive capacity or cloud allowance. | When my photo and document collection keeps growing, I need space for the files I intend to retain, not just a drive that holds today’s selection. For around 29% of consumers, capacity is the primary concern. |
| Offline access and portability | Check which cloud folders are available offline, whether the drive must travel, and which connections your devices can use. | I need to open or move important files even when the internet is unavailable, while accepting that a carried drive can be misplaced. Offline access or portability comes first for around 21% of consumers. |
| Compatibility and privacy | Check device ports and file-system compatibility before copying; if you encrypt a drive, keep its password or recovery key safe. | My copy needs to work on the computers I use, and I want to limit access to personal documents if the drive is lost. Around 14% of consumers make compatibility and privacy their main concern. |
Backup mistakes to avoid
-
Treating a synced folder as an independent archive
Google Drive Help says that files moved to Trash while mirrored or streamed are put in Trash everywhere. A local view of a synced file may therefore follow the same deletion as its cloud copy.
Keep a separately managed copy of files you may need to recover independently, and test how to restore it.
-
Leaving the only local backup connected
The National Cyber Security Centre warns that ransomware can reach attached backup storage. Keeping a removable drive connected between updates reduces its separation from the device it protects.
Disconnect the drive after updating the backup when you do not need it for active work, and store it securely.
-
Reformatting before safeguarding existing files
Apple warns that formatting erases files on a disk or volume. Its Disk Utility method for encrypting an external storage device also requires erasing the device first.
Make and check another copy of existing files before using an erase-and-format workflow.
-
Buying for a connector or speed claim alone
A drive still has to work with your computer, cable and file system. Samsung says the T7 Shield’s maximum stated speeds depend on compatible host hardware and connections; Apple distinguishes Mac and Windows-compatible disk formats.
List the devices that must read the files, check their ports and supplied cables, and decide on a suitable file system before moving the collection.
A different cable or adapter may be needed, and reformatting takes time if the drive arrives in a format unsuitable for your devices.
Relevant storage brands
These product lines illustrate different local-storage uses; a brand name alone does not establish whether a particular drive fits your library or devices.
Western Digital
A reference point for external hard drives used to hold a local household archive.
- Western Digital’s catalogue includes portable and desktop-style external hard drives; its listed My Passport range spans 1TB to 6TB on the referenced catalogue page.
- Check the chosen model’s capacity and connections rather than applying the range’s specifications to every drive.
Samsung
Relevant to people considering a compact portable SSD for carrying a local copy and transferring large files.
- Samsung’s UK T7 Shield page lists read and write speed ratings and resistance ratings under stated test conditions.
- Samsung says maximum speed depends on compatible hardware and cable connections; its resistance ratings do not replace a second backup copy.
SanDisk
Relevant to selected smaller collections moved between devices, as well as portable local storage.
- SanDisk describes USB-C and USB-A connectors on its Ultra Dual Drive Go for transfers between compatible devices.
- Confirm the capacity of the particular drive against the files you intend to carry; connector convenience does not establish that it will hold a full household archive.

SanDisk Portable SSD 2TB
This portable SSD provides a local-copy option for a collection that fits within 2TB.
Before choosing it for transfers between devices, check its connector and file-system compatibility with each one you plan to use. If the copy contains sensitive documents, also check whether its available protection meets your needs.
Questions about backup choices
Is cloud synchronisation an independent backup?
Not on its own if changes to the synced files affect every copy you rely on. Google Drive Help says that files moved to Trash while mirrored or streamed are put in Trash everywhere; keep a separately managed copy when you need recovery independent of that sync path.
Can I use one external drive with a Mac and a Windows PC?
Yes, if its connections and file system work with both computers. Apple identifies ExFAT as a Windows-compatible format for volumes over 32 GB and warns that formatting erases files already on the disk, so check the format before copying and safeguard existing files before changing it.
How can I protect personal documents on a portable drive?
Consider encryption that works with the devices you will use, and store its password or recovery key separately from the drive. Apple warns that its Disk Utility encryption workflow requires erasing the device first; Microsoft lists BitLocker To Go for removable drives on supported Windows editions and says a recovery key may be needed to regain access.
What else should I check before choosing a backup route?
Check the exact cloud plan’s storage allowance and recurring charges, or the drive model’s capacity, warranty terms and damage exclusions. A warranty does not replace a separate copy of your files: the National Cyber Security Centre’s backup advice centres on keeping important data in another safe location from which it can be restored.
