The way nodetool takes a snapshot of a keyspace is by creating a hard link to the SSTables. This means it is innately a full backup every time. You can enable incremental backups in Cassandra which will do a backup each time Cassandra flushes a memtable to an SStable. I don't believe there is a way to take a snapshot of JUST the last week of data in Cassandra using Nodetool.

Linking just in case you haven't seen the Datastax documentation around Snapshots and Incremental Backups.
