I have all the books in calibre except for ones from amazon. I am yet to work out how to add those to calibre. Once I do that I will open a dropbox account and upload there. For now I have them backed up on a 8gig usb stick. Tho that is messy as I have copies for my kindle my husbands android and my daughters kobo. I am reluctant to wipe any version incase one messes up when converting.
I will work this out but for the moment game of thrones calls and I want to start the second book
