Windows Server - Backup directly from rclone mount or Google File Stream to local disc & google drive?

So I had my data on my Windows Server available as a network file share & I was backing this up with Duplicacy to both a local disc & Google Drive & this has worked relatively fine. But I decided I wanted to migrate the live data to my google drive for convenience.

So now I want to do an active backup of the live data in my Google Drive to both local disc & Google Drive (seperate gdrive)

I have tried installing the native Google Drive client on my Windows Server and made it do a mirror of my data, then the client can run here & sync and Duplicacy will backup any changes in gdrive to local disc/gdrive. But I don’t really like this & think it’s a bit janky, it seems a little unstable.

I tried playing with Google File Stream mode for a bit and it seems I couldn’t target the drives in there with Duplicacy because they were virtual volumes and Duplicacy lacked permission or something? Even if I change it to ‘mount’ to a particular folder, I run into the same issue.

Then I have tried rclone mount (haven’t played with vfs cache yet) - here I could point Duplicacy to the rclone mount, then I imagine I can ask Duplicacy to backup from here to local disc & gdrive. Is this something people are using reliably? I would greatly appreciate it if someone has some good settings for the rclone mount; the disc it runs on is a fast SSD with over 100GB available space.

If I could get either Google File Stream or rclone mount to work reliably, then I could have 2 local backups (or remove 1 of them) as the live data would not need to be on the server at all, only backups. I also wonder how well restores would work in this configuration. When restoring I would be caching the restore to the mount and obviously have to wait for upload. But that would be the case with having a mirror sync on the server as well anyways.

Any feedback appreciated.
