Incremental Sync to OneDrive

[tonymet]

although wsl --export is great for complete snapshots, it's a bit heavy for frequent incremental backups.

Developers often need to sync their working sourcefiles from within WSL2 to Onedrive.

I've created an example script using robocopy & Windows Task Scheduler here.

It would be a great addition to WSL to handle this automatically.

I've tested using mklink but that seems to have poor performance
