Across the US, courts require data to be hard-deleted in cases of, for example, the expungement of a juvenile’s criminal record. This is a technical problem faced by all courts. Are you suspecting that courts are not taking backups, or that they are not properly wiping expunged records from their backups, or that courts employ developers that build bespoke backup pruning systems?

I used to do IT in the public sector but not for the court system. I'm saying that they're almost surely using some off-the-shelf backup tool and having "deletions will filter though the backups in $x months" as a good enough solution.

Reaching into the backups or doing per-record encryption isn't something that you can just buy at this point.
