The recovered server has to run through the part of the GCS data stream
that it missed the first time. This is not conceptually different from
recovering using archived WAL logs (or archived trigger-driven
replication data streams). As with using WAL for recovery, you have to
be able to archive the message stream until you don't need it any more.
