correct, write a script to run fastcopy and use task scheduler.
when i copy local to non-local, i use VSS and i have a wiki about it
https://forum.rclone.org/t/i-want-to-share-how-to-enable-vss-for-rclone/11644/8
i have a python script that generates commands for fastcopy, rclone, VSS and veeam.
the output, for fastcopy, looks like this
fastcopy.exe /cmd=sync /utf8 /verify /no_ui /filelog=C:\data\rclone\logs\keepass_home\20210320.114919\fc.log "c:\data\keepass\*" /to="a:\keepass\fc\"
