I archive.
The NZ threat is a threat to all of 8ch, not just QResearch - but mostly /pol.
You can start your own board and quietly archive what you want over there. I have my site fully backed up offline and I'm RTG with another+ if needed. Anything is possible - it just takes work+time.
If you want redundancy it has to be off of 8ch, and you have to do it.
