To find out if there have been any updates or new features added to Webuzo, I recommend checking the official Webuzo documentation or contacting the Webuzo support team or community forums for the most up-to-date information on available CLI commands and feature requests. They may have introduced new backup options or improvements in later versions of the control panel.
If you find that Webuzo doesn't currently support the specific backup functionality you need, you can certainly submit a feature request to their development team, as you mentioned. They often take user feedback into consideration when planning updates and new features for their control panel.
