ISPConfig 3 with backup system.
I think ISPConfig is verygood hosting solution but it has some problems.
1. Slow - Updating the changes is very slow. In the monitor ->show job queue, it takes long time to update.
2. There is no backup system of sites, emails, and settings.
3. Some times myDns stops, so need some control (to start/stop services) from panel.
I hope developers are working on those issue.
