I have two servers running Unraid. One was pieced together from stuff I already had just sitting around, bunch of mechanical drives for basic storage and to learn the software. The second is built with 10 SSDs for faster transfers to the server, with HDD for parity. My question is, how can I set it up so that everything from the SSD server gets transferred over to the HDD server, and clears out the SSD (using that server basically as cache for the slower one)? I know I could set up a task in Windows to accomplish this, but I'd rather not have to add in an additional system if not necessary.

You can use for example rsync over ssh, if you google that there will be lots of hits with various examples how to.

I'll look into it, thanks!

Works great via User Scripts for unattended weekly backup in my case.  I do not remove the content from the source server once copied to the destination server but there is an rsync parameter to do that.

That's a hell of a writeup, thanks for the link. I'll take a dive into it this weekend. To you point about removing content from the source server, I'm not doing anything "mission critical", just day-to-day data hoarding. The SSD server is only 1TB, the HDD one is 10TB, so that's where everything will live. Thanks again!

Yeah, it took me several days to wade through it all and get it to work properly.  You will see lots of my posts in that thread.  However, once you get it set up it is "set it and forget it."  This has been running flawlessly for me for over three years.  I'll pm you a copy of the script I use as an example.
