Encryption is server-wide, so when it is enabled you cannot choose to keep your

If your Nextcloud server is not connected to any remote storage services, then
it is better to use some other form of encryption such as file-level or whole
disk encryption. Because the keys are kept on your ownCloud server, it is
possible for your ownCloud admin to snoop in your files, and if the server is
compromised the intruder may get access to your files. (Read
