As a personal anecdote: I was a BackBlaze customer for over a year around 2011/2012. I backed up one computer with 2 attached hard drives.

Over a period of time one of the drives failed; slowly. It would lock up sometimes; and I would restart it. Months later I realized it was losing files when it did this. And when I tried to restore those files from BackBlaze I discovered that they had been purged; and that this was considered normal behavior.

BackBlaze had lulled me into a false sense of security regarding my data by claiming to back up my files but actually mirroring a hardware failure on my local system.

I had an unhappy email exchange with BackBlaze tech support, and also Brian, and came to realize how flawed the system was.

I switched to CrashPlan at that point.

I will not consider using a product that lacks proper file versioning; and a much longer lifetime for deleted files.
