Backup applications to PC via local network

I've installed [Neo Backup](https://f-droid.org/packages/com.machiav3lli.backup) which allows me to do (scheduled) backups of my applications data to device's file system. Now what I want is to use my PC as a storage for that backups, and transfer them via wifi. I have 2 Wi-Fi use cases: - When my phone and PC are connected to the home router, - And when my PC connected to the phone in hotspot mode. So I want backups to work in both cases. There are application named [SyncThing](https://syncthing.net) which I familiar with, but it's not suitable for my case because I don't want backups to be stored and take space on the phone at all. But one great feature of SyncThing is that both devices can find each other no matter which local network they are in. I tried [CIFS Documents Provider](https://f-droid.org/ru/packages/com.wa2c.android.cifsdocumentsprovider) , and it works, but only when I know exact IP or hostname of my PC in local network. It seems like what I really need is the similar application but with ability to find my PC no matter what IP or hostname it has. Anyone can suggest such, or maybe other solution for my needs?
