The web GUI for veeam displays the "Top Repositories" section, and shows how much of each repo is consumed. We built a pair of repositories using the Veeam hardened repository which does some great dedupe and compression. So much so, that the consumed space now exceeds the "space" that the repo reports it has available, which leads to this graph being a bit broken looking
Not really sure where to post bugs with the web gui.. or how it would be better to represent. I know on disk, I have 141TB Free, and that is represented in the console, but not the dashboard
