previous industry: particular production db had a few terabytes of data but didn't have customer data. We could just get a dump of prod db, not super sensitive, no drama. After we migrated it to aws rds we could just spin up new dbs from snapshots.

One colleague spent a few weeks pruning a db snapshot down to something minimal ish so our dumb old suite of regression tests with uncontrolled data dependencies could still pass. One off manual activity.
