For a household backing up photos and documents from one computer, start with an external drive that has room for the files and the backup history you want to keep, then set up regular backups rather than relying on a one-off copy. Keep an additional copy away from home if a fire, theft or other incident there could affect both the computer and its local drive. A network-attached storage device is worth considering when several household devices need a shared destination, but it needs its own backup.
If years of family files live on one computer, a separate external drive gives you a destination for regular backups. Microsoft Support describes File History backups to an external drive or network location; Apple Support says Time Machine can back up Mac files automatically. Check that you can restore a sample file before depending on either setup.
A drive used to exchange selected files has a different job from a dedicated Mac backup disk. Check the file format and connections for every device that will use it. Apple Support says Time Machine cannot back up to a Windows-formatted disk, so plan its destination separately from a shared Windows data drive.
Network-attached storage, or NAS, can give household computers a shared place for files and backup copies. Synology presents its DS223 as a home storage option, but the enclosure requires at least one SATA drive. Plan how the files stored on the NAS will be backed up elsewhere too.
Choose the backup process and where its copies will live before comparing drive connections or capacity. A separate drive helps with computer failure, but a copy kept in the same home does not cover every incident that could affect the original.
| Priority | What to check | Your needs |
|---|---|---|
| Recoverable copies | Set a regular backup schedule; confirm which folders it covers; restore a sample file to check the process. | I need new photos and changed documents to appear in the backup without remembering to copy them each time. |
| Capacity | Count the files to protect and decide whether to retain older versions. For Time Machine, Apple Support advises a disk with at least twice the Mac’s storage capacity; that is not a rule for every backup method. | There must be room for my collection and the backup history I plan to keep, not just today’s files. |
| Device compatibility | Check the computer’s port, the supplied cable and the drive’s format before use. Apple Support says Time Machine cannot back up to a Windows-formatted disk. | Our Windows and Mac devices may need to exchange files, while the Mac still needs a suitable destination for Time Machine. |
| Separate locations | Keep an additional copy away from the computer and home if a single local incident is a concern. NI Cyber Security Centre guidance calls for a copy kept offline in a different location. | If equipment at home is lost, stolen or damaged together, I still want access to the family files. |
| Several devices | Decide whether each device can use its own backup drive or needs a shared NAS destination. Check the NAS drives, setup and separate backup destination. | Photos and documents from several household devices need an organised place, rather than relying on copies gathered manually from each one. |
| Portable copies | For a drive you will move between locations, check its capacity, connections and backup-software compatibility. Treat a USB flash drive for selected files as an extra copy, not the sole backup of a large library. | I may carry a copy elsewhere, but I do not want that portable device to become the only place those files exist. |
Photos taken and documents changed after that copy will not be in it. A scheduled backup can reduce reliance on remembering each transfer, while a restore test checks whether you can retrieve a file.
Set up a regular process for the folders that matter, using a suitable tool such as Windows File History or Mac Time Machine, and restore a sample file.
Changing a drive’s format can erase its existing files. This matters when switching between a shared Windows data drive and a disk intended for Time Machine, which Apple Support says cannot back up to a Windows-formatted disk.
Secure another copy of the files before erasing a drive. Decide whether it will be used for file sharing or as a dedicated backup destination before formatting it.
One incident at home can affect both devices. NI Cyber Security Centre guidance recommends keeping a copy offline in a different location.
Maintain another copy through a secured cloud account or a drive stored elsewhere. If you disconnect a local backup drive between runs, reconnect it often enough for backups to continue.
A NAS still needs storage drives and setup, and files held only on the NAS remain dependent on that one destination. Synology says its DS223 requires at least one SATA drive.
Check the required drives and arrange a separate backup for the NAS files. Do not install a drive containing your only copy without securing those files elsewhere first.
These references help distinguish backup software, portable storage and shared home storage; a brand’s tools do not make every drive suitable for every device or backup method.
Time Machine is Apple’s automatic backup route for Mac files.
Windows households can consider File History for a local or network destination and Windows Backup for selected account-based cloud copies.
Samsung’s portable T7 SSD line is relevant when a local copy needs to move between devices or locations.
The DS223 is a NAS option for households organising files and backups in a shared location.
These portable SSDs and the external hard drive offer local destinations for copies of family files. Choose the capacity and connection for your devices, then arrange a repeatable backup and an additional off-site copy where needed.

A portable local destination for a copy you intend to move between locations. The product name specifies USB 3.2 Gen 2; check the connection, drive format and backup method against your devices, and assess whether 1 TB accommodates the files and history you want to retain.
No image available
A portable local-copy option if your files and planned backup history fit within 2 TB. Its product name specifies USB 3.2 Gen 2; confirm the connection and formatting for your chosen backup software, particularly if you intend to use Time Machine.

A local drive to consider when you need a portable copy and 1 TB suits the collection you will back up. The named connection is USB 3.2 Gen 2x2; check your device’s connection, the drive format and your backup software before choosing it.

This external hard drive offers a 5 TB local destination for a collection and the backup history you choose to keep. Check its format and the intended Windows or Mac backup process before use; secure existing files elsewhere before any reformatting. The drive alone is not an off-site copy.

A portable local-copy option if 2 TB accommodates your files and planned backup history. Confirm its connector, drive format and compatibility with the devices and backup software you intend to use; arrange a separate off-site copy if a home incident is part of your backup plan.
A one-off copy gives you another set of files, but it will not include later changes unless you repeat it. Set up a regular backup for the folders that matter, using a suitable process such as Windows File History or Mac Time Machine, and test a sample restore.
Do not assume a shared data drive will also work as a Time Machine destination. Apple Support says Time Machine cannot back up to a Windows-formatted disk. Check the format needed for file exchange and arrange a suitable Mac backup disk or volume separately; copy existing files elsewhere before reformatting.
Apple Support advises a backup disk with at least twice the Mac’s storage capacity for Time Machine. That recommendation is specific to Time Machine; for another method, assess the files being protected and how much backup history you want to retain.
It needs to be available when a scheduled backup runs, but disconnecting it between backups can reduce its exposure to a problem affecting the computer. NI Cyber Security Centre guidance recommends an offline copy in a different location. Reconnect the drive regularly and check that the backup schedule continues to run.
Cloud storage can provide an off-site copy, while a local drive gives you another way to retrieve files if cloud access is unavailable. For family files you cannot replace, use the two as separate copies where practical, and check which folders the cloud service protects and whether the account has enough storage.
