It seems a very specific Venn intersection to utilize technology to a high degree, but also to imagine and prepare for its worst case failure.
Maybe the NZ tech-prepper crowd?
The off-site backup storage was required by several of our largest customers due to the critical nature of our software.
The risk from not being able to recover your data because of something wrong with your process (like, you are not backing up all the data you need) dwarfs the risk from backblaze to lose your data
Of course, that risk may be entirely acceptable; it's all about risk mitigation and trade-offs, not perfect security.
The solution is to do both, or all three (or n), where #3 is another backup process. And to test the backups of all processes by trying to read or restore them (onto empty disks) regularly.
I.e., somewhere on a continuum between zero or minimal and the above, depending on how critical your business is.
Because Murphy's Law.
Edited to add:
And how critical your job is (to you).
Of course there is much more to the whole issue, like funds, PHBs, etc.

Even monthlies have a value in the worst case scenario.
