It is a good point that Word doesnt do versioning for a file saved on disk (as far as I know) while it does in sharepoint (I'm not familiar with onedrive).

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.

Word has track changes which lets you view what changes have been made and who made them. But you need to turn this on (I think it's under "Review"), and you should still follow the rule of "save early, save often". C-s is my fidgety muscle-memory behavior when otherwise staring at the computer screen trying to decide what to type/do next.

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.
