(Or on macOS, using a file system which supports Browse Versions and enabling Time Machine backups as well.)
For things you really care about, periodic cloud backups and/or cloud saves as well, and periodic print copies for good measure.
The saddest thing is when someone's laptop with all of their data or documents is stolen, or their data/documents are destroyed physically in some disaster, and they have no backup.
Fortunately I learned this lesson as a kid playing countless hours of RPGs where forgetting to save frequently lead to replaying hours of gameplay again... ;)
I’m a developer so this may not be for everyone.
I use markdown+git for documents.
If I must use office, I write in gitlab markdown first (auto backups) and then copy into office
A third option is "LibreOffice Writer". I have not lost a doc/sheet on it yet. Even if I shutdown the system with an unsaved doc, the next time I open writer, it will prompt me for recovery. The caveat is, there might be small formatting and alignment differences. When I open a MS doc in Libreoffice, it output is formatted a bit differently but it might not be Libreoffice and might just be because of the different font stack available on my Ubuntu OS. Libreoffice is available for free though. So you can give it a try.
If I'm working on high value documents (reports for work) I regularly save separate timestamped backup copies in a different location anyway, especially if it's a collaborative doc like sharepoint or google docs. But I'm sure i would have been caught by this too, I wouldn't do it more often than 1/2 daily except under some special circumstance.
You could just use google docs, I think it has versioning, though I don't know what triggers a version.
It's not quite the same as versioning, because it's still possible to clear out the history of changes (in fact, when you accept changes that's what it does), but it's pretty effective.
OneDrive won't change anything if you never save. From Word's point of view it's a regular path and just like writing to a disk.
You need to turn on AutoSave. https://support.microsoft.com/en-us/office/turn-on-autosave-...
