I tried Backblaze but couldn't get over its insistence on first backing up my entire primary hard drive instead of allowing me to simply choose directly my most important files in my external drives, or from wherever I prefer. Seems arbitrarily forceful to me, though the pricing and security options are good. Also, the interface of deselecting things to not back up via exclusions, instead of simply being able to specifically select what you WANT to back up is absurd, it complicates things unnecessarily if out of dozens of folders, you only want to select a few essentials for cloud storage.

As far as pricing goes, $5 per month for 100GB seems steep. SpiderOak offers 400GB for less than that and so does Nordlocker (though Nord has its own problems). On the other hand, iDrive has been offering a whopping 5 terabytes for a whole year for just $3.98 in a deal I saw just a few days ago.

Overall, zero knowledge backup is the best route, Backblaze plays at that, on the other hand I wouldn't touch any backup offering by Google with a 10 meter cattle prod. Grotesque that they reserve the right to snoop right through your files unless you first encrypt them externally via third party apps.

It's still a loss (for the current year).

But this is a SaaS, working with recurring revenue.

Some metrics to consider are:

- Cost of Customer Acquisition

- Lifetime Value

They could spend 200$ to get an average customer, but they will renew their subscription for an average of 5 years and generate over 2000$ in revenue during that time.

As long as you keep track of these metrics you know you're in a good direction or digging yourself a hole.

Besides other costs R&D, Admin, Marketing and Sales can be scaled up and down as needed, and become a smaller part of the costs as the company grows.
