I've got 3 copies of the blockchain ( plus the associated files and wallet data), and I run 2 nodes.

I copied the directory onto an SSD, and gave that to a new installation of Core under Ubuntu. It asked me for the directory address, and when I replied, it went ahead and veried the copied chain, and synchronised it. It even gave me the correct info in the wallet.

I'm impressed with core, it seems to be extremely stable, it even runs under Windows without any problems.
