You can purge data from an active database.
That doesn't mean the data is purged from any of the backups that are done of the database.
Matter of fact, since purging data from a backup defeats the purpose of doing a backup, then it's very plausible to believe every entry ever made in NICS is still able to be retrieved - provided the right backups of the data are available.
Which is a catch 22..
The "right" backups would be 100% consistent with best practices.

FWIW - I spent from 1993 until August of last year when I retired as a network engineer and database administrator.
The latter ten years of my career were mostly devoted to database administration./database retrieval.
