The short answer
Section titled “The short answer”Sync is not backup. OneDrive keeps a copy in the cloud, but if you delete a file and the deletion syncs, the cloud copy goes too (version history may save you, if it is enabled and you notice in time).
Use at least two different mechanisms:
- Files: OneDrive or Windows Backup for continuous copy + version history.
- Offline copy: an external SSD/NAS, disconnected after the backup.
- System: a full image or a tested reinstall plan, so a dead SSD is an inconvenience, not a data loss event.
Test a restore before you trust any of them.
The three options
Section titled “The three options”| Windows Backup | OneDrive | File History | |
|---|---|---|---|
| Primary job | Files/folders/settings to OneDrive | Sync + cloud copy | Versioned file copies to a drive |
| Needs Microsoft account | Yes | Yes | No |
| Offline copy | No | No (unless you download) | Yes, external drive |
| Full system image | No | No | No |
| Version history | Limited by OneDrive | Yes | Yes, per file |
| Best for | Home PC + OneDrive | Daily documents | A local external drive |
Windows Backup is the modern consumer flow; File History still exists but is not a full image tool. Neither replaces a real image/restore plan.
A practical 3-2-1 plan
Section titled “A practical 3-2-1 plan”- 3 copies: working file, cloud/OneDrive copy, offline external copy.
- 2 media: internal SSD + external SSD/NAS (not a second partition).
- 1 offsite: cloud or a drive kept somewhere else.
For the OS:
- Keep a Windows install USB and your driver pack.
- Keep a full image if you have a tool you trust and have restored it once.
- Otherwise, keep a written reinstall + app list + licence list. That is slower but honest.
Before you rely on it
Section titled “Before you rely on it”- Pick one important folder.
- Delete a test file or restore a previous version.
- Confirm the restore works on a clean profile or another PC.
- Check the backup job actually ran (not just “enabled”).
- Save the BitLocker recovery key outside the machine.
What not to do
Section titled “What not to do”- Do not use a second partition on the same disk as “backup”.
- Do not keep the external drive connected 24/7; ransomware can encrypt it.
- Do not assume OneDrive covers
AppData, VMs or a database. - Do not enable BitLocker without saving the recovery key.
- Do not call a backup “verified” until you have restored something.
