Chapter 7. Backup and Restore

Cassandra is a highly available peer-to-peer distributed database. Data is partitioned and replicated among multiple nodes and different data centers in Cassandra, and therefore, data backup and restore might seem redundant. However, there may be scenarios where a client application, or due to some other reason, data is corrupted and a need to recover arises. Cassandra provides recovery options and tools to take data backup. In this chapter, we'll discuss those tools and techniques. Sometimes, there may be a need to migrate data from a NoSQL database to Cassandra, so we'll discuss that too. In later parts of this chapter, we'll discuss how to replace, move, and remove nodes from a Cassandra cluster.
