My backup is a Drobo NAS (which is RAID like) with 5 SATA drives and double redundancy -- I can lose two drives at once and still have all of the data. If the controller fails, I can move the 5 drives to a new controller. I am backing up all of my data and documents daily. Right now it is a mirror except with no delete. I plan to change to a weekly full plus daily change dumps (probably a three cycle) and then I will have multiple copies on the NAS.
