Purging and backup GL_Interface_History Table

Summary:

I would like to check if the GL_INTERFACE_HISTORY Table behavior as below as we are leveraging the table to build a report:

1. Can store the data for how long? Will the data forever keep there until we internal people manually purge it?

2. What is the program to purge it?

3. How to do a table backup in case someone incidentally purge the table?
