Which "stuff"? 

If you mean the traceback, no, that didnt tell me anything I didnt expect.

If youve sent some other stuff, it didnt arrive. I have had some other emails 
delayed or lost over the weekend, so please resend.

I suggest untarring a typical backup and examining the content. It will 
contain one file for every new revision of every modified object. You can use 
the dumpdsf tool on those files (or a subset of them, if there are too many) 
to see which classes are causing the backup bloat.

My guess is that you are using ZCatalog, and your ZWiki page changes are 
causing many BTree node objects to be modified. I'm not aware of any way to 
avoid that.
