Subject Re: Cassandra backup and restore procedures

I'm sorry if this was covered before, but if you lose a node and
cannot bring it (or a replacement) back with the same IP address or
DNS name, is your only option to restart the entire cluster?  E.g. if
I have nodes 1, 2, and 3 with replication factor 3, and then I lose
node 3, is it possible to bring up a new node 3 with a new IP (and a
Seed of either node 1 or node 2) and bootstrap it?

Thanks,

Simon
