In this chapter, you understood what backups are and the different types of backups, along with the different storage media used for backups. You also learned about HDFS backups and covered the basics of using the Hadoop utility—DistCp. Next, we covered Cloudera's backup options, replication, and snapshots using Cloudera Manager.

In this book, we started out with the very basics of Hadoop and walked through the entire Cloudera distribution, covering each and every aspect of managing Hadoop clusters that run CDH and Cloudera Manager. Using the knowledge acquired from this book, you should now be ready to take up the responsibilities of a Hadoop administrator and get start managing huge Hadoop clusters.
