My opinion on backups is pretty simplistic. If a restore of my backup
doesn't bring me back to what I had when I backed up then I don't have
a backup.
If I have to restore something and the relationship between files that
were hard linked in the past is lost that might not be something that
I even notice immediately. Maybe not until the file is changed and
now there are 2 versions of it in different places since the
relationship is gone.
Either way, not backing up the hard link relationships duplicates data
on both the backup and on any potential restore.
But even more importantly, the original question was about excluding
all files with linkcount>1 from backups. That means that any file
important enough to have in more than one place would in fact never be
backed up at all. That is crazy.

The solution is not to refuse to backup any file that is a hard

ignoring them means you aren't backing up everything.
I agree that preserving hard links may be important in some
situation. There are certainly legitimate reasons to preserve hard
links within a backup.
To more than a couple of years I have been weighing up the
advantages and disadvantages relating to including a hard link
preservation support within LBackup. The latest alpha build of
LBackup now includes support for hard link preservation.

This is not crazy. Why a privileged user need to create multilevel hard
links . This issue has been approved by secunia security community.
Hope they will report it as a vulnerability , because this POC has been
exploited successfully and it is affected by all software that use
rsync as a backup and restore tool.
