Hello @Stal,
Thank you for mentioning my post about Pika Backup tool.
So, I have been using Pika for the last 2 months. I am definitively switching from Deja Dup to Pika. The interface and browser tool management for backups in Pika are really good. However, I have not seen any comments from users with more experience yet.
Have you tried the tool?
What do you think about it?
