SSH key setup for remote borg backups

[JonahGroendal]

I see that Nextcloud AIO officially supports remote backup locations from within the AIO interface, but I don't see any option to generate ssh keys or to get the already-generated public key that borg will use to connect to the external location.

Do i need to exec into the docker container and generate the keys manually? If so, will these keys be a part of the backup?

Also, how do I configure nextcloud to use append-only mode when communicating with the remote borg repo?

Hi, the key will be automatically generated and shown in the aio interface after you click Create backup the first time.

I see, thank you. I wasn't able to find any documentation on that, and having to attempt a backup without first setting up ssh keys is a bit unintuitive. Perhaps a message to illuminate this behavior could be added to the AIO page when changing/setting backup locations.

How can I tell nextcloud to use --append-only?

You cannot

I believe it's using --append-only by default (or any least trying it) actually since I have command="borg serve --append-only" before nextcloud's ssh key in my authorized_keys

Edit: I misunderstood. That actually replaces the command that nextcloud sends, forcing it into append only mode. So that's probably the way to do it
