Need suggestions for setting up backups between a local and remote server (lemmy.ml)

Hi everyone! I am relatively new to self hosting and I am in the process of repurposing an old desktop computer as an offsite/remote server that I will have at a friends house.

My setup:

Local: RPi 4 running openmediavault
Remote: HP EliteDesk SFF running TrueNAS SCALE

My plan was to connect the machines using tailscale and use the borg plugin in openmediavault to create a remote server repo and save deduplicating and encrypted backups from the local server to the remote server. However, it seems that in order to do that I need a borg plugin installed on the remote server for which there doesn't seem to be a truenas app for. I know I could probably install it on the truenas server, but from what I have read, a truenas update could wipe the install and configuration.

Thus, I would appreciate any suggestions on making the above possible, or alternative setups that would help me achieve what I am looking for. My requirements are:

Openmediavault on the local server
Encrypted backups
Machines connected via VPN (tailscale was just so easy so I would prefer to continue using that, but I can be convinced otherwise)

Thanks but I'm limited to openmediavault on my Rpi locally. I wanted to try something a little more powerful like truenas to get more experience different linux-based systems. But given that I currently don't have any major plans for the remote server other than storing backups I may just put a distro that I can install borg on like others have suggested.

No worries, also just to let you know. I have a TrueNAS and a unraid server.

The TrueNAS server has a Unraid samba share mounted. Within TrueNAS you setup a pull task where it copies files from your remote system to keep the directory in sync. Any changes on my unraid samba share are backed up to my TrueNAS share on a predetermined schedule.

You might want to look into the pull task on your TrueNAS which will be a lot easier then trying to push files from your OpenMediavault.
