Remote site Uploading Subs to Home Desktop Using the Google Drive App

That's exactly what I am doing currently with my remote scope at Starfront Observatories. There is nothing you need to do in NINA. Just sync the folder that you are saving your subs to with Google Drive and have it sync on your office computer. I didn't notice any negative effects on NINA itself during acquisition with my MeleQ3. I did notice some lag introduced if I am using Google Remote desktop to do things while imaging, but this seemed to subside after the first night. Right now every morning I wake up to a nicely synced folder full of new subs on my office drive at home from Google Drive. 

It also helps with cleanup on the remote PC, because as soon as I move the files out of the google drive folder on my office PC, it also deletes it on the remote PC. Has been working fine for me the last few weeks.

That's a good question. I use Box.com, but that works probably very similar to Google Drive. When I setup my architecture, I chose specifically for a separate syncing application, for the following reasons:
- More control over when files are uploaded, should there be bandwidth limitations interfering with more urgent tasks
- Cloud storage is always birectional, so deletions on either side propagated as well, which can cause surprises. Again, a separate syncing app gives more control
- I needed a syncing app anyway to also grab some files that are on local network drives at the observatory (weather reports, SQM readings, etc).

As syncing app, I use GoodSync. 

The files are still uploaded to my Box cloud service, where my home PC downloads them as soon as they appear. So when I wake up, the files are on my home PC. It's just an extra app in between with more control.

Google drive is an excellent idea for that. I don't use it for astro photography, but I use it for other purposes. I have different computers and need some of the data in a latest version on each of them. This way, I didn't have to care for syncing these files. But that's not the point. Once installed and set up right on the computers you want to use it, it works perfectly well for me for years now. For all of the software on your PC, it's just a local folder and everything works like usual. The GoogleDrive app runs in the background and looks for changes in that local folder as well as the cloud folder. If something changes, it begins its magic.

The only thing that can be a limiting factor is the standard cloud size of 15 GB. Depending on the resolution of your camera, the exposure time (the number of frames you shoot - problematic especially with LRGB where you use shorter ones), this sometimes can be a bit on the small side. The recycle bin folder (that lets you restore your data if you deleted it) will collect a lot of images and eat up some of the space as well. So you have to empty it manually or set the time to keep deleted images to a shorter period (if possible, never tried it). But that all seems to be a no brainer if you upgrade your account. In the worst case, if your cloud space is full, the files will not be delivered to the other computer. In this case, you might want to take care of it manually or delete some files not needed anymore somewhere. But your data stays on the remote PC and nothing will be lost what can't be fixed at some point.

I love these kind of tools. They made my life so much easier.
