For household photos and records that would be difficult to replace, use a recoverable local backup and a separate off-site copy, then test that you can restore a file. An external drive can provide local recovery, while cloud backup can protect a copy away from the computer; whichever you use, check what happens to older and deleted versions. File sync helps you access current files across devices, but synchronised changes and deletions make it a poor substitute for a separate backup.
If restoring many files over the internet would be inconvenient, a scheduled backup to an external drive gives you a local copy. Keep another copy off-site so an incident affecting the computer and nearby drive does not remove both.
Keep a recoverable copy separate from the computer, with earlier versions available if files are changed or damaged. The National Cyber Security Centre advises making regular backups and not leaving a removable backup device permanently connected.
Check which folders are synchronised, whether important files are available offline and how long deleted or earlier versions can be recovered. Microsoft Support explains that OneDrive changes and deletions synchronise between the computer and cloud account.
Decide first how you would restore important files after a computer failure, then make sure a separate copy can survive a problem affecting the computer and its nearby storage.
| Concern | What to check | Who this matters to |
|---|---|---|
| Local recovery and capacity | Check that the backup tool includes your important folders and can restore earlier versions. Allow space for the selected files and retained copies; Apple recommends a Time Machine disk with at least twice the Mac's storage capacity. | If a computer fails, I want to restore a large photo or document library locally rather than download it all. About 34% of consumers put local recovery and capacity first. |
| Off-site recovery | Check where the separate copy is stored, how changed or deleted files can be restored and whether a removable drive can be disconnected between backups. | A nearby drive could be affected by the same loss or damage as my computer, so I need a copy elsewhere. Off-site recovery is the primary concern for about 33% of consumers. |
| Access across devices | Identify the folders that sync, whether essential files are available offline and what independent backup covers them. | I use files on more than one device and want access to current copies without losing a way back after an accidental edit. About 20% of consumers primarily value that access. |
| Privacy and encryption | Confirm encryption support for the exact drive or service, and establish how you would recover the password or key. Check before using a method that may erase an existing disk. | If I carry a drive containing personal records, I need to consider what happens if it is lost and whether I can still unlock my backup. Privacy and encryption come first for about 13% of consumers. |
Microsoft Support says OneDrive additions, edits and deletions are reflected between the computer and cloud account. Its file-version support page describes a 30-day retention period, rather than indefinite access to older versions.
Keep a separate backup of irreplaceable folders and check how to restore an earlier or deleted file.
A connected drive may be affected along with the computer. The National Cyber Security Centre advises that a removable backup device should not be permanently connected.
Connect it for backups, confirm they complete, then disconnect it. Keep an off-site copy as well.
A missing or damaged file may no longer have a recoverable earlier version after the service's retention period. Backblaze describes a default 30-day version history and longer options.
Check the retention setting for your account and practise restoring an older file before relying on the service.
Encryption features depend on the model and setup. Apple Support says its cited Disk Utility method of encrypting an external device requires erasing it first; losing the password can prevent restoration.
Check the exact drive's instructions, preserve existing files before any erase process and keep recovery information somewhere other than the drive.
Windows households can use File History for repeated backups to an external or network drive. Windows Backup folder protection uses OneDrive for selected folders.
Time Machine provides a Mac backup workflow using external storage.
IDrive offers personal cloud backup for households seeking an off-site copy.
Backblaze offers personal cloud backup for computer files and selected external drives.
Seagate's One Touch external-drive line is relevant to local copies made with a backup schedule.
These portable hard drives and SSDs can provide local storage for household computer backups. Before choosing one, compare its capacity with the files and versions you plan to keep, confirm your backup software can restore them, and maintain a separate off-site copy.

This portable hard drive provides a 4TB local destination for household files. Check file-system compatibility before using it with a Mac or another operating system, and pair it with software that can restore the versions you need.
No. Microsoft Support explains that changes and deletions in a OneDrive folder synchronise between the computer and cloud account. Version history may help you recover a file within its retention period, but keep a separate recoverable copy of files you cannot replace.
Allow space for the files you select, earlier versions and future growth. For a Mac using Time Machine, Apple recommends a backup disk with at least twice the Mac's storage capacity; that guidance is not a universal rule for other backup tools.
A removable backup drive need not stay connected. The National Cyber Security Centre advises against leaving it permanently attached; connect it for backups, confirm completion, then disconnect it and keep it safe. Set a routine that reflects how often your files change.
Check how long changed and deleted files remain recoverable and how to request a restore on your chosen account. Backblaze describes a default 30-day version history with longer options, while Microsoft Support describes a 30-day file-version period for OneDrive; confirm the conditions that apply to your service.
Restore a file or folder to a separate location, open it and check that it is the version you intended to keep. The National Cyber Security Centre advises checking that you know how to restore your regular backups before you need them.
