@pgregory3508 two options to consider -

Git, eg Github - add the sample Unity .gitignore file to your root project directory, then commit via git like any other git project
- FYI this is how we work at Axomem. Git is more than a source code repository - its a major productivity enhancer and sanity maintenance tool (once you get over the learning hurdle)
Sync your project directory with a OneDrive folder using something like RoboCopy or Rsync.
- Suggestion- use the .gitignore file above as input to exclude certain directories that are not needed, especially Library, Build, Temp, Obj etc
- Might be worth creating a batch or shell file to do this along with putting exclusions in files, eg link
