The problem re-occurred (already some time ago but I just now came around to fix it).
In the end, it only started working again after I downloaded a fresh copy of SD and replaced the one in my /Applications folder with it. Before that I went through seven debugging rounds, always repeating all previous measures and adding one or two additional things. I cannot say that replacing SD in Applications was sufficient it but it was a necessary ingredient.

1) Deleted schedules, deleted 'Scheduled Copies' (in ~/Library/Application Support/SuperDuper!, restart computer, re-create schedule, saved SD settings, quit SD, ejected disk, re-connected disk --> nothing happened

2) Deleted schedules, deleted 'SuperDuper!' (in ~/Library/Application Support), restart computer, re-create schedule, saved SD settings, quit SD, ejected disk, re-connected disk --> nothing happened

3) Deleted schedules, deleted
- 'SuperDuper!' (in ~/Library/Application Support) and
- both 'com.shirtpocket.backuponmount' plist files (in ~/Library/LaunchAgents),
restart computer, re-create schedule, saved SD settings, quit SD, ejected disk, re-connected disk --> nothing happened

4) Deleted schedules, deleted
- 'SuperDuper!' (in ~/Library/Application Support) and
- both 'com.shirtpocket.backuponmount' plist files (in ~/Library/LaunchAgents),
- 'blacey.SuperDuper!.savedState' (in ~/Library/ Saved Application State)
- 'SuperDuper!_xxx.plist' (in ~/Library/Application Support/CrashReporter)
restart computer, re-create schedule, saved SD settings, quit SD, ejected disk, re-connected disk --> nothing happened

5) Deleted schedules, deleted
- 'SuperDuper!' (in ~/Library/Application Support) and
- both 'com.shirtpocket.backuponmount' plist files (in ~/Library/LaunchAgents),
- 'blacey.SuperDuper!.savedState' (in ~/Library/ Saved Application State)
(- 'SuperDuper!_xxx.plist' (in ~/Library/Application Support/CrashReporter))
- 'com.blacy.SuperDuper!' (in ~/Library/Caches)
restart computer, re-create schedule, saved SD settings, quit SD, ejected disk, re-connected disk --> nothing happened

6) Deleted schedules, deleted
- 'SuperDuper!' (in ~/Library/Application Support) and
- both 'com.shirtpocket.backuponmount' plist files (in ~/Library/LaunchAgents),
- 'blacey.SuperDuper!.savedState' (in ~/Library/ Saved Application State)
(- 'SuperDuper!_xxx.plist' (in ~/Library/Application Support/CrashReporter))
- 'com.blacey.SuperDuper!' (in ~/Library/Caches)
- 'com.blacey.SuperDuper.xxx.plist' (in ~/Library/Preferences)
- app.com.blacey.Superduper!.playlist (in ~/private/var/db/BootCaches/xxx)
restart computer, re-create schedule, saved SD settings, quit SD, ejected disk, re-connected disk --> nothing happened

7) Deleted schedules, deleted
- 'SuperDuper!' (in ~/Library/Application Support) and
- both 'com.shirtpocket.backuponmount' plist files (in ~/Library/LaunchAgents),
- 'blacey.SuperDuper!.savedState' (in ~/Library/ Saved Application State)
(- 'SuperDuper!_xxx.plist' (in ~/Library/Application Support/CrashReporter))
- 'com.blacey.SuperDuper!' (in ~/Library/Caches)
- 'com.blacey.SuperDuper.xxx.plist' (in ~/Library/Preferences)
- app.com.blacey.Superduper!.playlist (in ~/private/var/db/BootCaches/xxx)
- Replaced SuperDuper!.app in Applications with a newly downloaded copy
restart computer, re-create schedule, saved SD settings, quit SD, ejected disk, re-connected disk --> nothing happened

After step 6) I had to 'unlock' something (probably because I had deleted stuff in /private/var). And when it worked after step 7) I had to authorise a new application inside the SuperDuper! bundle to be run for the first time (because it was downloaded from the internet.

Next time the problem re-occurs, I'll start debugging from the other end (ie, start with replacing SuperDuper!.app and then add the boot caches and so on). If you are interested in the SuperDuper!.app bundled that needed replacing, I can retrieve it from a backup and send it to you.
