I'm a new user (of Turnkey and of server environments in general) so I apologize if my questions are very stupid and have very obvious answers. I wasn't able to find relevant information in the documentation, though. The question is this: how can I get different appliances to communicate with each other and share common data folders? If there are instructions or tutorials on how to do this, please just point me to them.
Here's why I want to do that. I have two TKL appliances (and I'm planning to install more) running within the Proxmox VE. One is the Torrent Server Appliance and the other one is the File Server Appliance. The purpose of the Torrent Server Appliance is obvious. With the File Server what I want to do is to manage the backup copies from all the computers connected to my network. What I want, though, is to be able to gather all those files (the downloads from the torrent server and the folders with all the backup files) in a single folder so that I can make periodical backup copies of this folder on to an external drive or NAS.
I imagine that this shared folder would have to be within the Proxmox VE since now this is the only thing I have installed on the server hard disk. I'm planning to add some more hard disks to the server, though, so the shared folders could also be (perhaps preferrably?) in an independent hard disk or partition. How does one go about doing this, though? How about saving or synchronizing this folder with a NAS in my network.
I was thinking that one possibility was to have File Server appliance copy the completed files from the Torrent server appliance and then backup all the files on to the external hard drive or NAS but how can one appliance communicate with the other to do that?
Again, I think this is very simple but I guess I'm not using the right keywords to do the searches and I can't find the relevant information in the available documentation. Thanks in advance for your help.
