Can we restore snapshot taken from 3 node cassandra cluster (RF is 2) in 1 node cassandra cluster?

Question

I have 3 node Cassandra cluster in production with replication factor 2, currently, I am taking the snapshots of this production cluster using "nodetool snapshot" and copying all snapshot directory to s3.

Now I need to restore this snapshot backup on s3 to dev 1 node Cassandra cluster.

Answer 1

Yes. You can restore data from snapshot to a node using sstableloader. Refer the link to know about sstableloader usage
