@scottalanmiller they just are not set to because I was not sure if that file type would work with standard incremental backup software (windows backup) without breaking things (being a dependable recovery point)
Sometimes they are not powered off when at home and work is done and changes are made.
A perfect solution would be something that would back them up daily if they are powered on or off but not sure if anything like that exists as that would normally be 2 different products.
