My backup setup 2

In the previous posting I defined my 3 kinds of data. In this posting I will tell how I back it up:

1. Okay to loose.
   This data I store on my NAS - see previous postings about a NAS. It protects me resonably from drive crash, but theft, fire, flood, human error etc. is not covered. However, it is still a very cheap way to have copies of a lot of data on two drives which is often updated.
2. Harder to replace.

3. Ireplaceable.
