I wish someone would send me tutorials
That is exactly what I am seeing when I look at this meme
Alternative approach. Why not upload files directly into a SMB share that is mounted inside of #Nextcloud using browser Web GUI? Just configure client not to sync that share locally. I do this with files I don't need all the time, but might want to pull something like an appliance PDF manual one in a blue moon.
You can still use #NextCloud. But to make it work as you are describing the following is required.
1) Create an SMB share
2) mount SMB share into Nextcloud
3) Each time there is a file change on the SMB share run a bash script to backup to a backup folder that will have every file. inotifywait can monitor any changes
I think you can configure Nextcloud version control and trash bin retention
./config/config.php
'versions_retention_obligation' => '60, 180',
'trashbin_retention_obligation' => '45, 90',
Read about these two, and set a number of days that work for you. This will
enable you to get deleted files from the trash bin and you can recover files of a specific version.

It sounds like you need a backup solution. Nextcloud syncs to make sure folders are the same. What you are describing exists in Syncthing. It has a mode to copy to a client and never delete.

I use Gitea and it works great as a docker container
