If I had a small business of any sort...I would backup manually each week, using a program akin to Macrium reflect. The most important thing would be to understand how to quickly re-establish a working system, in the event of catastrophe.
I don't believe in storing anything of value online, just a personal quirk. It seems absurd to me that I should ever trust someone that I've never met...with data I consider valuable/essential...when I can store it with greater piece of mind myself at a secure offsite location.
They sell multi-TB hard drives for less than $100 these days...it seems absurd to pay anyone to store 50GB or so of data when that 20 times that amount can fit on a 1TB hard drive which can stored in a safety deposit box or some such. Readily accessible when needed.
Another possible storage location (IMO) would be your accountant, assuming that you keep books, pay taxes, etc.
There are alternatives that fit...whatever it is that you may desire.
