It's getting stranger:

At this very moment a backup started saving 9.2 GB!
Although it just did a backup!
I'm pretty sure that I didn't touch that amount of data since this  
early morning I went to bed!

But it's even better - see this log entries:

Mar  1 10:58:09 boskop-2 /System/Library/CoreServices/backupd[8042]:  
Copied 11835 files (14.0 MB) from volume Macintosh HD.

Backup completed successfully.

I didn't do anything which justifies a backup volume of 9.2 GB ... not  
at all.  WTF?

I'm desperately looking for a logfile which tells me what's going on,  
besides that thin information in system.log.

Any hints?  Jay?

   cheers,  Michael.
