Backing up and restoring the profiler database

Using certain scripts that can be executed by the root users, you can back up of the profiler databases. Later, if you want to delete the existing Cloudera Data Hub cluster and launch a new cluster, you will have an option to restore the old data.

Cloudera Data Catalog includes profiler services that run data profiling operations on data that is located in multiple data lakes. In VM-based environments, the profiler services run on a Cloudera Data Hub cluster. When you delete the Cloudera Data Hub cluster, the profiled data and the user configuration information stored in the local databases are lost.
