Copying multiple folders across different drives/partitions on Windows

fwiw, with my backup script, every time it is run, creates an temp link, run rclone, then deletes the link.
i do this as part of creating a VSS snapshot, which is the source for rclone.
this is using variant #3 from my handy, dandy wiki
https://github.com/rclone/rclone/wiki/How-to-enable-VSS-for-rclone

mklink /d b:\snapshot\ %shadow_device_1%\
rclone sync b:\snapshot\data\ dest:data
rmdir b:\snapshot\

another workaround, also from my wiki, but using variant #2

rclone lsd c:\
