It’s centered around a simple YAML configuration format and includes a desktop GUI and webDAV server for browsing snapshots. Developed by the same team that created Vorta and Borgbase, I’ve been testing it and it’s quite fast and user-friendly.
From the graphs it seems that the initial naming for it was V'Ger, what would had been a good match with Borg and Vorta in the Star Trek based naming scheme.
It was a bit surprising that, coming from the same team, it didn't use the same repository format, for more or less the same use case and feature list (may it be related to its native support of S3?)
