Public bug reported:

First of I would like to express that I'm quite disappointed by sbackup
not being backwards compatible with 1.4 snapshots. When you are in need
to restore a snapshot you more often than not don't have time for such
stuff as "converting backups", which I generally think is a STUPID idea.

PLEASE MAKE THE RESTORE BACKWARDS COMPATIBLE!!!

Solution to the problem:
change line 1069 of /usr/share/sbackup/sbackup/ar_backend/tar.py from
fd = open(self.snpfile, 'w')
to
fd = _FOP.openfile_for_append(self.snpfile)
