Nextcloud NFS Data Folder. When is the encryption happening?

Hello

I would like to move my data folder to an nfs mount. I am worried about unencrypted data send through network since nfs is unencrypted by default. My question is:
When I upload data when is it encrypted? is it stored and sended through network before hand or does the upload process already encrypt it and is that true for all the clients?

Thanks :slight_smile:
