Brandon Williams commented on CASSANDRA-3706:
---------------------------------------------
bq. We should probably add another ("cluster_system"?) that is reserved for
internal use but is replicated normally.
The wrinkle in this is something we've encountered before... what do we set the
RF to when we don't know how many nodes there will be?

> Snapshot can backup user data, but it's also nice to be able to have
> known-good configurations saved as well in case of accidental snafus or even
> catastrophic loss of a cluster. If we check for changes to cassandra.yaml,
> cassandra-env.sh, and maybe log4j-server.properties on startup, we can back
> them up to a columnfamily that can then be handled by normal snapshot/backup
> procedures.
