[rdiff-backup-users] Destination doesn't support hard links, workaround?

[Chris G]

I am trying to do some backups to a network disk but I get the
following error:-

    Warning: hard linking not supported by filesystem at 
/freecom/backup/var/www/rdiff-backup-data
    Traceback (most recent call last):
      File "/usr/bin/rdiff-backup", line 23, in <module>

override_chars_to_quote = ctq)

line 245, in is_case_sensitive assert not upper_a.lstat()
    AssertionError

The network disk is essentially a 'black box', i.e. I can't change
what it does at all.
