Chapter 9. Configuring Backups
As Hadoop clusters mature, the data residing in them grows, and maintaining a copy of the
data turns out to be an important responsibility of a Hadoop administrator. Backing up data
from a distributed environment is a challenge due to its ever increasing volume. Setting up
backup operations is an important step towards restoring data in case of entire cluster fail-
ures. This chapter discusses the various backup and data protection options and will cover
the following topics:
• Understanding backups
• Understanding HDFS backups
• Using the
distributed copy
(
DistCp
)
• Configuring backups using Cloudera Manager
