There are some details to work out as outlined above, but a "complete backup solution" typically revolves around the 3-2-1 philosophy.
3 copies of your data 2 copies on different types of media ( such as cd/dvd and HDD) 1 copy of your data offsite (a location other than where you created the data) If you want to know HOW to implement a 3-2-1 backup solution, you will want to start answering the questions presented above.
