Is there a way to daily backup the warehouse and lakehouse contents?

Hi Let's say I have a dataset with incremental refresh configured such that it refreshes the last one month of data, daily. In this scenario, suppose I want to perform a one-off full load, then how do I action this?

Can someone help me understand following about internal shortcuts: 1. Is it allowed to create shortcuts in both lakehouse and warehouse, or is this lakehouse feature only? 2. Can internal shortcut point to lakehouse within a workspace? 3. Can internal shortcut point to lakehouse outside a workspace? 4. Can internal shortcut point to warehouse within a workspace? 5. Can internal shortcut point to warehouse within a workspace?

Some quick questions if anyone has good hands on with git integration. Say workspace is connected to main branch. 1. Suppose I make a change to the report file (pbir) via Power BI desktop and push this file to the main branch, then does the workspace immediately get the change? Or is there something I need to do to pull the changes into the workspace? 2. Do the changes immediately sync into the workspace app (assume one was published prior to the change)? Or do I need to update the app? 3. Usually one cannot delete a report from workspace if that report is part of a workspace app. But suppose I delete the report from git (via Azure devops) then what is the behaviour to expect?

At 02hr 5min in your video, you mention about a workaround to dataflow external parameter, where one can create another query within power query to achieve this, can you give me a brief example of this approach?
