Nodetool snapshot, consistency and replication

Hi there,

I have a question about the nodetool snapshot.

Situation:
- 3 node cluster
- RF = 3
- fully consistent (not measured, but let's say it is)

Is it true that when I take a snaphot at only one of the 3 nodes this
contains all the data in the cluster (at least 1 replica)?

With kind regards,
