i haven't done the cost analysis, but for a medium to larger environment i think tape and local onsite backups are cheaper. LTO-4 tape is dirt cheap and the big investment is the robot and backup software
It will be cheaper. Well you have to invest in the hardware. Then there is the time it takes to set it up and configure it properly. Those are all up front costs and you can amortize those over time. Then buy as many tapes as you want. They last a long time and you will want as many as you can handle and afford.
There is one word, though, that is key to what you say. That word is onsite. If you are going to use tapes, and I am not saying that you should not use them, then at least put some kind of strictly enforced off site rotation plan into place.
Talk to someone who has has a building fire, flood, storm damage, or earthquake
