They did not become clear to me. Why can't you put read caps in the backup log? I guess in general you don't want to do that unless, of course, you want someone having access to the backup log itself to give them access to all the files. Do you want that? Something we generally do is, if we *don't* want that, then we use the verify cap instead. For example the 'recent uploads and downloads' page in the WUI shows the verifycaps of each file or directory. Would it make sense to use verify caps in your backup log? (One potential problem is that it is more expensive to compute verify caps than to compute a flat hash of the plaintext of the file.)
