Yes, I purge the raw data too. I've resolved to purging once a month and it seemed to be quicker logging in and to enter the purge dates but takes a long time to purge - hours; and this month I got this error trying to purge twice"Indexed columns are not unique". It takes me hours to purge and now I'm not even sure if it's actually purging. I haven't had the time to try it again. Do you know what is causing this message and how to speed it up?
