Agree that Power BI is not a database to hold all historical data.
In this case, you could export data from this table into another table in database daily (maybe need more DB experience or automatic tools) and add a Date column in the new table which records when new data is inserted. Then connect to this new table with Power BI. You can also export data into other data sources like Excel or CSV files with exporting datetime in filenames. Then connect to these files and combine them into one table with Power Query Editor.
