Plot directly to another machine’s drive via internet


I’ve been researching ways to save the plot from a harvest machine directly to the drive of a farm machine without having any intermediary steps beyond the temp folder.

I read that plotman can do something similar through rsync- by archiving the plot to another location. But I’m asking because my harvester machine only has 2 drives and id like to stripe them together using raid 0 and parallel plot using both drives (won’t have any space to save the finished plot except another machine).

Or as someone else asked- can you just do this by selecting the temp folder in the second drive for half the plots?

What file transfer protocol is recommended for machines connected only via internet? Thanks
