I think there was some talk of using Nabu Casa for snapshots at some point. Here’s the FR: Nabu Casa - Configuration Backup
And I made this comment back then:
Paulus was just talking about cloud storage of the config via Nabu Casa being a distinct possibility on Frenck’s livefeed. Sounds like he wants it to happen.
I haven’t heard anything recently, though, and a simple implementation where the snapshot is written locally and then uploaded doesn’t address this specific issue.
