Here is a small script to remove hard link of a rsync based backup, by days.
I have use it to cleanup my backup and find when different version of file have been created.
find . -type d > dir_list0 # my dir list is of the form ./2010/07/22/home cat dir_list0 | cut -f1-5 -d/ | grep home | sort | uniq > dir_list # delete all hardlink, keep just the one is the oldest dir cat dir_list | while read i; do find "$i" -type f -links +1 -delete done; #delete broken symlink find . -type l -xtype l -delete #delete emtpy dirs find . -type d -empty -delete
