I’ve always heard that you folks like to keep tons of backups of your stuff. I have also heard that there is this 3-2-1 rule about keeping you backups. My question is: do you follow it personally or is it something that people just tell you to follow?
There are excellent articles that go over all this. Do a something search.
Bottom line, yes, you should at least do 3-2-1 methodology. More than that is gravy.
