Just to reminder you that these dont last forever. Some of the early chan-threads with material backed up to archive.is are already dead. My suggestion would be that you use HTTrack website copier. It can copy as many sites as you want which are then linked to the original site you start with. It is nasty to configure, so I will give you some tips: maximum depth( for links which stay on the same address) minimum should be 2, external mirroring depth never above 1, as with each hop the amount of data downloaded rises exponentially. With default-settings it downloads at 25kb/s, you can alter that in windows to 250-500kb/s. While it could be interesting to download "parts of the internet" with external depth well above 2, you may get legally in severe trouble because sometimes, altoughh extreme rarely people post direct links to Childporn images. So make sure that you have good OPSEC. Best would be Tails+Tor+VPN
