@bmike I haven't, except once (maybe twice) purely for troubleshooting purposes (and not for the purpose of freeing up space per se).

@Monomeeth Me neither - only to poke at it to answer here. I’ve never had space get to a point where I had anything fail or have to tip the scales to prune things even once.

Wow - they were about to install something needing 50 GB. I almost agree that sort of installer should fail rather than try to prune backups or hope it finds enough space as its writing..
