I will mention it again, as I think it has real merit. *Restic* is working very well for me. It is written in Go so there are builds for just about anything you can think of. I have it running on my FreeNAS box pushing snapshots to B2 and then a second set to a RPi running on my network with their very simple `rest-server` which acts as another backup source (2x4TB USB HDDs attached). So now I have two full sets of versioned backups, all accessible from any computer on my network via the `restic` CLI tool.
There is no UI so I realise it won't suit everyone, but it is very simple to use and there is excellent documentation.
