the answer is yes! https://docs.opencloud.eu/docs/admin/welcome/features#files-on-demand

may try to give it a spin later this year

How is the file sync integration? Even some of the commercial products have shocking implementations.

Does it support shadow copies of files?

Has a nice UI, let’s me mix and match disks, let’s me host docker containers plus a VM with gpu pass through.

All basically out of the box. (Ok - Pass through was a bastard) All for a one off price.

I don’t know if there are other options that let me do all of that, unraid has always been the one mentioned.
