I'm not really following this thread, but that's wrong. A lot of people use hardlinks to provide snapshot functionality. I.E. the following can be used to efficiently make snapshots: rsync /src/ /backup/today cp -al /backup/today /backup/$Date See also: http://www.dirvish.org/ http://www.rsnapshot.org/ http://igmus.org/code/ > Also, just adding hard-links doesn't increase the number of inodes. I don't think that was the point.
