I'll modify my rsync command to preserve hard links.
note that on a large file system with a large number of files, thats VERY expensive, as rsync has to keep a list of every inode number on the whole file system and verify each directory entry isn't pointing to an inode its already linked. if there's a few million files, this data structure gets HUGE in memory.
I would hope that rsync is clever enough to do this only for non-directory files with a link count greater than 1. Yes, for some backup archives that still could be the vast majority of the files.
