One comment - running all fulls on the weekend is an extremely bad
practice, if something happens on Friday, then you lose a week's worth
of data, depending on your incremental schedule. A better practice is
to run Fulls each day of the week and split it up in your environment.
When the connection is cut the jobs should fail, but I have not done
too much with DSSU/disk backups myself to comment on that part.
