and then didn't take the simplest 101 steps to protect his data.

That is Not. Accurate.

The databases are likely too large for cloud backup. He had on premise dual drive backup. Without knowing exactly what happened, apparently both the "donor drive" and the "patient" drive failed. From the thread:
It's rather embarrassing to even be in the position of needing to recover a hard drive. Ultimately, it can be partly blamed on Windows Update. A couple months ago, Windows Update forced me to accept an update with too many bugs in Excel and Access, so I had to restore an operating system image with an older version of Windows. I totally forgot that restoring the Windows image causes all kinds of problems with Backblaze that need to be resolved after the restoration, so nothing was backed up since then.

Since I started using Backblaze, I've only been doing physical drive closing every several months, so my last full drive clone is older than the data on Backblaze.


"It's probably worth ordering more than one donor drive. I suspect that the data recovery technicians accidentally broke the donor drive that I provided them with during the first head replacement attempt, so if it happened once, it can happen again.
It was necessary to hunt for hard drives with exact specifications for drive matching, including being manufactured within 3 days of the original failed drive.

Zeelotes' small band collaborated to crawl the web to find hard drives, data recovery companies, ship them to Australia, and more than reimburse him financially for his expenses.

.... "Well, it turns out that Recovery Squad damaged the platters of my drive beyond any possibility of repair and were probably lying to me every step of the way.

It will be a long (probably multi-month) programming project to get the GTR1 database updating again." ...

didn't lose anything that is absolutely irreplacable. It's just that programming isn't the way I wanted to spend all my days off work for the next few months. (I also didn't really lose any code. The programming I have to do is special-purpose for extracting data from the binary format of the GTR1 backtester files, which I've never needed to do before, and adapting code that will no longer work with certain raw data files gone.)


So, please - stop.
