link-dest and batch-file

I don't know how the OP manages their backups. I write out a
backupname.current symlink pointing to the new backup once it is
completed. That is what I use as the --link-dest parameter and what I
would restore from. If a backup is aborted in the middle, doesn't
happen at all, or fails the symlink isn't changed and the last one that
worked is still tagged current.
I also name the rsync target dir backupname.incomplete and rename it to
backup.$Date when the backup completes so that there won't be any extra
date stamped dirs in the list to affect when it is time to delete old
backups and so I won't ever try to restore an incomplete (at lest not
without knowing that I am doing so).
