I respectfully disagree. Doing them on a schedule means you have the data when you need it. What's the harm? I cannot tell you how many times in my career (Global IT Director for a major Pharma) I heard..."we don't have a current backup", or "Oh crap, the last backup was corrupt".
My system has taken many many hours of hard work to get it right. I want to make sure I can recover quickly when the time comes.
FYI - the only reason I might reduce my Allonis specific backups is because of my Virtual Environment and the ability to have Clones and Snapshots.
