Hi, Sven. No need to post here and send support mail -- you just double the amount of answering I have to do!

Here's what I sent to you via email: Partition the drive into backup and data partitions. You're much better off doing that, since you'll be able to boot from the backup (assuming a Mac-supported drive), and you'll be able to isolate data from backup.

I discuss this in some detail in the User's Guide ("Storing a backup alongside other files on a destination volume"), so take a look there for extended discussion. But -- my suggestion is to partition.

Hope that helps.
