If I wanted to run bitcoin on multiple machines on my LAN, and I wanted to copy the block chain so that it doesn't have to re-download, which files do I need to copy? I'm guessing
are necessary, but what about
I've actually copied the blockchain before, and the two above files were all that I needed to get it to work. I'm pretty sure that the others are checkpointing files, and it's not a bad idea to let the new client checkpoint the entire blockchain after a copy anyway.
I'm not certain, however, as that client was a while ago, and predates the checkpointing upon startup thing.
