How does the wildcard thing work, is it (in unix terms) globbing (I guess) or regex (probably not)? And how do I work with drive names (mount points) that have whitespace in them (the 0.5 manual explains neither of these).
If the partition is called “Backup Disk”, the mount point is “/Volumes/Backup Disk” and I would suspect that I need “/Volumes/Backup Disk*/” for alternate-target-paths and a target-marker to make sure Duplicati does not create the directories when the disk is not mounted. Correct?
Without globbing it could work too but it would not be robust in case a second partition named “Backup Disk” is mounted.
