SD no longer honouring backup-on-mounting-drive

[Manu Chao]

What do you mean with 'turning off the backups'? Unchecking both checkboxes in the dialogue box showing up when clicking Edit in the 'Scheduled Copies' window?

And it now does so, ie, deleting the scheduled copies removes those two plist files. I only had discovered these two files relatively late in my debugging process (I was first only looking out for files with 'superduper' in their name). It is thus possible that I had set up a new scheduled copy (which didn't work), then deleted all files with 'superduper' in their name without first deleting the scheduled copies from within SuperDuper with therefore these two files remaining.

In short, I cannot say for sure that deleting the scheduled copies from within SD did not delete these two plist files. I only know that a new 'installation' of SD, encountering these two files failed to start upon mounting a destination volume (of a newly scheduled copy). And I know that only deleting the scheduled copies from within SD followed by deleting their folder in Application Support did not solve the problem.

But the next time this occurs, I will first check whether deleting the scheduled copies from within SD actually removes those two files or if them getting stuck might have caused that problem. (I might even be able to test this by booting of a clone from a few days ago.)
