     Hardlinks. See also: rsnapshot, which uses it to give you daily/weekly/monthly deduplicated backups at the file level.
     
     Original idea here: http://www.mikerubel.org/computers/rsync_snapshots/
     
     The tool it inspired: https://rsnapshot.org

     ahh wtf you're right i thought it was -b and --backup-dir but it's --link-dir for the hardlinks???
     
     what does it even do? i can't tell at the moment, i need to trace it. does it perhaps quickly do a hardlink/copy to a local dir before the transfer so the files don't change?
     
     i need to dig through the source code now too...

     @feld @subleq
     Uhm. rsync -b doesn't do hardlinks, it just creates a copy of an existing file before overwriting it...
