not everyone is a sys admin worth his/her salt
Some of the readers on tech republic are indeed new to managing systems or may be home users with a recent interest in the subject. One can't assume everyone reading the article already knows this stuff though it may be review for those of us who've seen it before. You could have chosen to skim the article and move on or skip it all together rather than taking the extra time to express your feelings of entitlement for something you don't pay for.
The real value in an article like this is the potential discussion afterwards where us readers may provide new and interesting solutions or strategies beyond what the article provided.
Here, I'll start:
The 3,2,1 strategy
- Have 3 seporate backups at minimum
- Have them on 2 different forms of storage media at minimum
- Have 1 of them off-site at minimum
(Thanks to a Security Now listener for that one. I'm just repeating it here.)
