Hmm. I thought I'd done three backups - one unscheduled which didn't delete, and two scheduled which did. Looking back at logs, I think I may only have done the latter two. Both were scheduled Smart Update, both said Time Machine backups would be preserved, and in both cases, when I clicked Schedule..., the Time Machine backups were deleted.
I noticed that the log says "Copying copy files with delete," but maybe that's normal.

Also, these are Time Machine server backups from other client machines, so they're .sparsebundle files. Does SuperDuper also make sure those don't get deleted?
