Best I know of for that is something like lrzip still, but even then it's probably not state of the art. https://github.com/ckolivas/lrzip
It'll also take a hell of a long time to do the compression and decompression. It'd probably be better to do some kind of chunking and deduplication instead of compression itself simply because I don't think you're ever going to have enough ram to store any kind of dictionary that would effectively handle so much data. You'd also not want to have to re-read and reconstruct that dictionary to get at some random image too.
