You can backup a Cassandra node by running the snapshot command:

$ nodetool snapshot

When you take a snapshot of a table, the backup is created in the snapshots subdirectory of the table. For example:

/path/
  to/
    data/
      keyspace_name/
        table_name-UUID/
          snapshots/
            snapshot_name/

Note that in Cassandra a snapshot is equivalent to a cold backup since SSTables are immutable (they don't change once written to disk).

For more information, see Backing up and restoring data in Apache Cassandra. Cheers!
