From my perspective, it seems that you're headed in the right direction when it comes to your dilemma with YaBB.
The information that I have in the YaBB forum that I operate is hardly important since it's just an entertainment portal that's specific to one production, i.e., it's simply being used as reference points. The sudden loss of that forum wouldn't shutter the production even though it would be an unwanted, and major inconvenience.
In your case, all of that translated news about Poland, including all countries in Central and Eastern Europe seems to be very important information. I'm glad that you have backups of it all; at least 80% of it.
Regarding the backup you have of YaBB on your PC, I hope it's not just the actual YaBB backup. In other words, I hope it's a backup of your actual files. My preference is to use WinSCP for my backups. Flat files have the advantage of being searchable, which can be very helpful.
By the way, like you, even though I'm on my cell phone a lot, I'm a desktop guy. That's my preference. I think a lot of people are that way even though the stats I've seen over the years show that websites are mostly accessed by smart phones. Of course, as you pointed out, discussions are few these days because the keys are too small for long posts.
Luckily, though, pinching & resizing a smart phone's screen makes reading a YaBB forum pretty easy to do. It's not mobile ready like phpBB or SMF are, but it's not that big of a deal for me.

This is very easily said, you should say that to a city library one day when it is totally burned down.
Ironically, your example of a city library burning down is exactly what happened to the Central Library in downtown Los Angeles in 1986. I remember it well. That fire damaged more than one million books. The library was closed for seven years. Particularly for the employees, it was a devastating loss. A lof them suffered anxiety, and depression because they were no longer serving the public.
There's an African proverb that says,
"When an old man dies, a library burns to the ground." I realize this won't be much of a consolation to you, but a lot of webmasters administered their entire websites through their YaBB forums. When that software failed, or when it became obsolete, and inoperable, their websites were effectively shuttered.
The solution? Create a new index page, explain what happened, and tell your website's visitors to stay tuned.
For me personally, a setback like losing a YaBB forum will inspire me to change operations for the better. I won't like it, and I'll surely complain like you're rightfully doing, but my intention will be to continue to see the glass as half full.
You seem to be the kind of person who figures things out. After all, you've already come up with solutions to your dilemma with YaBB.
Take care.
