Figured it out - if Time Machine is backing up to the same volume, then it locks down the permissions on the mount point - can't even "ls /Volumes/Delorean" (yes, I named the drive Delorean). This also explains why it would fail sometimes, but not every time. Ever since Snow Leopard, Time Machine has been backing up every hour - and if it happens to be running when SD starts, it clobbers my SuperDuper backups.
I just verified this by running a SD backup - no problems. Then unmounted Delorean, started a Time Machine backup, and tried SD. Bam - failed.
