Erm, if you delete the Full the Incrementals are based on, you can throw
away the Incrementals just as well in almost all cases. So if you e.g.
do 1 Full every week, rest incrementals and radically delete everything
that is older than 14 days, you can restore 1-2 wekks, depending on the
date of failure. In that case an official retention period of 1 week is
much more honest together with recycle oldes volumes.
