Fellow selfhoster, do you encrypt your drives where you put data to avoid privacy problems in case of theft? If yes, how? How much does that impact performances? I selfhost (amongst other services) NextCloud where I keep my pictures, medical staff, …in short, private stuff and I know that it’s pretty difficult that a thief would steal my server, buuut, you never know! 🤷🏻♂️
TPM is a good way, Mine is setup to have encryption of / via TPM with luks so it can boot no issues, then actual sensitive data like the /home/my user is encrypted using my password and the backup system + fileserver is standard luks with password.
This setup allows for unassisted boot up of main systems (such as SSH) which let’s you sign in to manually unlock more sensative drives.
