NCP backup -- incremental?

Hello, I recently migrated to NCP.

On my old nextcloud setup, I used restic to backup my data directory, nextcloud folder, and database. However it was not automatic, and I don’t remember how to set it up again.

In NextcloudPi, I notice that there is an automatic backup function. But unfortunately I cannot find much documentation about it except for a few how-to articles.

Before I dive headfirst into this backup tool,

  • Is there any way to read more about how it works under the hood?
  • Is the data backup incremental, or will it backup everything every time?
