Additionally, as someone who has been a part of the interview process for IT people, if you only have two people and you're not an expert yourself there's a non-neglible chance that neither of the two people you've got are particularly good at their job. I'd advise any company to just accept the premium cost of using cloud services rather than risk getting ransomewared or what-have-you and finding out nobody ever actually tested the backups.

The cost of getting things wrong with on-prem aren't high on the average - but they sure are spikey if you get unlucky.
