HUMANS? Mike, you need to spray for those.

Sounds like you have a good setup.

Me, however, I'm old fashioned. I don't believe in anything other than local 
backups drives (some redudants are stored off site for safety) and DVDs. I 
have a MASSIVE collection of DVDs books spanning back to 1995. I just popped 
one in from 96 and copied the data to an ssd, just to see if I could do it.

No school like old school.

But seriously Mike, spray for those humans. They have diseases.
