Create a symbolic link tree that shadows a directory structure
find -L ./ -type l -delete
And then removing empty directories
find ./ -type d -exec rmdir 2>/dev/null {} \;
**Actually after some finding I found lndir which creates symbolic trees but it wasn't in the Arch repos so.. ;)

cp -al src destRather than dangling symlinks, which can also be found using the "symlinks" command, you will end up with files with a hard-link count of 1.find src -type f -links 1 -deleteFinally you can tidy the empty directory command:find . -depth -type d ! -name . -exec rmdir --ignore-fail-on-non-empty {} \;This version will remove deep, but empty trees, and it won't complain about non-empty dirs.echo foo>file;ln -s file symlink;cat file;echo whoops>file;cat symlinkThis creates a file, symlinks it, edits the file, and changed your "backup". Hard links aren't safe either. do the same thing, only, you have to look harder to find out it's a link.echo foo>file;ln file hardlink;cat file;echo whoops>file;cat hardlinkThe only way to back up the data is to actually copy it elsewhere. If you want to back up and save space, then rsync is your friend. It has some parameters that will compare to previous backups, and copy any changed files since the last backup, and hard link the rest. This way, you can delete any backup you want, and all others are unaffected. I can't tell you what they are, but google will help out: http://www.google.com/search?q=rsync+incremental+backup You may also be interested in Flyback, http://flyback-project.org/ , which is a gui wrapper over rsync. Good luck!
