It also says only 113 files (of 50285 total) were transferred, i.e. 50172 files should have been hard-linked. 4.5GB of file data was transferred, so the number of 5GB you mention sounds about right. > And using Rsync 2.6.3 on this one. Hmm, I don't think that had the --itemize-changes option yet; you may consider upgrading... You could of course (right after an rsync run) do a "cd newdir; find . -type f -links 1 -print" and then randomly check a couple and compare all their attributes such as mtime, permissions to the previous dir. (I still recommend using the --link-dest thing over using cp -al first.)
