Disagree. We run fulls weekend and incr during week. Works for us.

An outage or Disaster could occur anytime, not just at the weekend.

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.
