That version is very out of date; please try the latest release from
http://www.greenend.org.uk/rjk/rsbackup/

What is supposed to happen is that when the pre-backup-hook fails,
rsbackup does not backup that volume. See the check on rc in
https://github.com/ewxrjk/rsbackup/blob/master/src/MakeBackup.cc#L301
for instance. So if the issue persists with the current version, check
what exit status your script produces when the mount operation fails.
