For irreplaceable photos and important documents, a local-and-cloud arrangement is the more resilient choice when practical: a disconnected local copy supports recovery without internet access, while an off-site copy can still be available after loss of the computer or local media. The National Cyber Security Centre advises keeping backups separate from original data, while Microsoft notes that edits and deletions in a synchronised OneDrive folder can also reach the cloud.
Family photographs and videos can be impossible to recreate after a computer failure, loss, theft, fire or accidental deletion. The National Cyber Security Centre recommends considering both cloud and removable-media copies for irreplaceable data.
Files visible in a cloud folder may still need a separate recoverable copy. Microsoft explains that additions, edits and deletions in a OneDrive folder synchronise in both directions, so restoration and retention settings matter.
Choose a file system before moving a local backup drive between computers. Apple identifies ExFAT as Windows-compatible, and warns that formatting a drive erases its contents.
Start with recoverability, then check how the copy behaves when files change, whether every household computer can use it, and what is needed to keep cloud access secure.
| Priority | What to check | Your needs |
|---|---|---|
| Recoverability | Keep a copy separate from the computer; confirm how files are restored; test a small restore after setup. | I want to retrieve important files after a computer failure, loss, corruption or accidental deletion. |
| Sync behaviour | Check whether edits and deletions synchronise; review version history, recycle-bin retention and full-account restore options. | I need to know whether my cloud folder is a working copy, an archive or a backup with recoverable earlier versions. |
| Drive compatibility | Check the file system, ports, cable and host USB capability; copy existing files elsewhere before reformatting. | The drive needs to work with the computers in my home without unexpectedly erasing existing data. |
| Cloud access and terms | Review sharing controls, password and two-factor authentication options, storage conditions, renewal terms and deletion rules. | I want household photos and documents to remain appropriately protected and accessible over time. |
Edits or deletions in a synced OneDrive folder can propagate to the cloud, so recovery may depend on a limited version-history or recycle-bin period.
Before relying on sync, check deletion behaviour, version retention and restore options, and keep another copy of irreplaceable files.
The National Cyber Security Centre warns that ransomware and other malware can affect attached removable media as well as the computer.
Run scheduled backups, safely eject and disconnect the drive when it is not needed, then store it securely.
Mixed Mac and Windows use can require a different file system from a Mac-only drive, and advertised SSD speeds depend on the computer, cable and USB mode.
List every computer that needs access, check ports and format requirements, and copy files elsewhere before formatting.
Reformatting can erase existing drive contents, and an unsuitable cable or USB port can limit transfer performance.
Synology states that RAID does not protect against accidental deletion, ransomware, theft, fire, flood or multiple-drive failures.
Use NAS redundancy for availability where needed, but maintain a separate backup destination and test restoring from it.
A separate copy may require additional storage or a cloud-backup subscription.
Relevant for households considering external hard drives or supported Seagate and LaCie storage with accompanying backup, mirror and security software.
Relevant for portable external SSD buyers who prioritise quicker transfers and a compact drive for moving backups between locations.
Relevant for a household wanting a network-connected central storage hub instead of repeatedly attaching a USB drive to one computer.
Relevant for Windows and Microsoft-account households wanting cloud-synchronised access and important-folder backup integrated with a computer.
Relevant for UK readers considering a dedicated multi-device cloud-backup subscription rather than a sync-first cloud folder.
These Joybuy options are external drives for keeping a separate local copy of photos and documents. A local drive is most useful as part of a routine that also considers secure storage, disconnection after backup and an independent off-site copy for irreplaceable files.

Not necessarily. Microsoft states that adding, changing or deleting a file in a OneDrive folder also adds, changes or deletes it on the OneDrive website and vice versa. Treat synchronisation as convenient access, then check version history, deleted-file retention, restore options and whether another independent copy exists.
Choose based on how you will use it. An external HDD suits a local archive kept at home and disconnected after backup; a portable SSD is more suitable when you carry it often or faster copying matters. Check the exact computer port, cable and USB mode, as maximum SSD transfer speeds can require specific host support.
Yes, but check the format before use. Apple identifies ExFAT as Windows-compatible and suitable for Windows volumes over 32 GB, while APFS is Mac-focused. Reformatting erases the drive, so move any existing files to another location first.
Test after initial setup and periodically afterwards. Confirm that recent photos and documents are present, then restore a small selection to a different folder or device. The National Cyber Security Centre advises checking that backups contain important data, including recent cloud files or newly created folders.
