I'm afraid making your own backup from a working device is already not possible.
For example, microcontrollers nowadays have internal flash that can be read-protected, so an attempt to read from such a protected chip will return only 0xFF. Even the humble Arduino Uno (ATmega328) can be read-protected. Same for FPGA's with internal flash (e.g. Intel/Altera MAX10 series). And when the flash is external, then the data can be encrypted so a data sniff during boot won't help much either, unless the encryption can be defeated.

We have a 1 million USD 32 channel Keysight parallel-bit-error-rate-tester at work that is out of support for the simple reason that MS stopped providing security packages for XP.
I cringe whenever I see professional, high-end equipment running on any version of Windows, and subject to the blue screen of death. The same goes for the typical other alternatives of Linux, which I don't consider to be any more robust. And adding the word "embedded" to the front of the OS doesn't seem to make it any more stable. Why can't these vendors invest in a truly stable OS for their high-end gear?

Big brands (Keysight, Tektronix, Fluke, LeCroy, R&S, NI, etc) are losing market to new low-cost players, and this will accelerate this process.

Are they? In what market segments?
In all market segments where a non-big-brand device is being purchased.

In all market segments where a non-big-brand device is being purchased.I would guess that the big brands are not selling products in the low cost market where they have no products (and never have) and aren't attempting to compete.
A while ago, very few people considered buying a scope other from a big brand.
A few years ago, the low-cost chinese scopes (as Rigol or Siglent) are the bestsellers for the Entry Scope market (even in American Colleges and Companies).
The low-cost scope profits feed the R&D for mid-range and high-end scopes. It's clear to see a trend, soon the big brands will be surpassed in all devices (PSU, AWG, DSO, SA, DMM, etc) and segments (low <200MHz, mid <1.5GHz, high >1.5GHz).
IMHO, the FIRST manufacturer to release the Hardware Design and the Code in a "GPLv3" license, and support the community to improve it, will "Dominate" (conquer the passion) from the Open-Source Communities and Crowdsourcing Market.
They do seem to be nipping at the heels of the big dogs, but IMO they still aren't really competitive with anything but the lowest tiers of the A-brand offerings.
show me a market segment anywhere where open source 'dominates'
WRONG - your perception is that chinese instruments aren't dominating in the entry-level market? ok, just google "best oscilloscopes", LOL.

I'm not even going to try to respond to the rest of your incoherent ramblings, but the whole point of what I said is that there has been an 'entry level' market for oscilloscopes and other test equipment for a very long time and none of the players in that market have gone on to become an A-brand leader. The A-brands don't really compete in this area and they never have. Where did I say that Chinese instruments weren't dominating the current entry-level market? I'm well aware that they are and I don't think that gives them a clear path to join HPAK/Tek/R&S/LeCroy anytime soon. "Making hundreds of millions"--where do you get your facts?
That's certainly no surprise. The entry level gear is a very good value, it offers a lot of bang for the buck and it is affordable to the hobbyist or pro-sumer who is probably not going to spend thousands or tens of thousands of dollars on high end gear. It is obviously not as good as the expensive stuff and it doesn't try to be, the thing it focuses on is being affordable.
In the past test instruments were divided into separate markets of service instruments and laboratory instruments. The low tier manufacturers provided service instruments and the high tier ones laboratory instruments. Some companies like Tektronix tried to provide both in separate product lines. (1) The various newer companies like Rigol and Siglent may have started providing low end instruments only really suited for service work but now bridge that divide with their high end instruments.

With the current trend, I see everything will be closed and locked-down and encrypted, first to a certain brand and environment, and very soon (as in a few decades away from now) we will see everything (everything as in objects, services, etc.), even your faithful DMM or your faithful handgun, everything will require a personally encrypted key and a valid personally authorization, or else that object/service won't be available to you.
This will happen whether we like it or not, simply because the actual level of technology allows to have that.

Oh well, I didn't mean it that fast, though!
