You don't?

This cuts both ways. I've seen plenty of litigation go south because one side had evidence and the other side had nothing because they deleted/shredded/lost the proof.
That's great, and for some things the court can ask you "Well *why* haven't you got it?" and then you're fucked. Now you're explaining in front of a parliamentary committee why you destroyed what would turn out to be evidence.
Unless you're required to retain logs for some reason like a litigation hold or legally or contractually mandated retention period and you violate those, while the adversarial party might be annoyed at you for not retaining logs there isn't much they can or will do beyond being annoyed.
Of course if you destroy logs after being notified of litigation or inquiry, you're gonna have a bad day.
And for some of that, the "legally mandated period" is "since the beginning of time itself".
Find anything?
