Dean,
your workaround is no workaround. It doesn't matter if you do the search catalog or browsing interactively through the resource selection. There is always for every incremetal backup much too much useless information. I consider this as BUG not as enhanced functionality.
Even the wasted disk- and tapespace ist a serious problem since I'm talking about several TB of data and some 100 thousands of directories that are listed and backed up useless every single day...
So again, is there any way to get rid of this?
