I ran a backup of my 5 network drives, selecting ALL files. Are any automatically excluded? I have unchecke the boxes that indicate excluded files. If none were excluded, and the backup was done correctly, then TI did much better than Retrospect 6.5 in compressing the files. The most recen Retrospect backup used 818MB, TI used only 635920KB, that's a big difference. I'll run another Retrospect backup, in case I have actully changed the files, but I doubt it.
