Best practices for backing up a NetBackup for Hadoop cluster

Before backing up a NetBackup for Hadoop cluster, consider the following:

  • To backup an entire NetBackup for Hadoop file system provide "/" as the backup selection and ensure that "/" is snapshot enabled.

  • Before you execute a backup job, ensure for a successful ping response from the backup hosts to hostname (FQDN) of all the nodes.

  • Update the firewall settings so that the backup hosts can communicate with the NetBackup for Hadoop cluster.

  • Ensure that the local time on the HDFS nodes and the backup host are synchronized with the NTP server.

  • Ensure that you have valid certificates for a Hadoop cluster that is enabled with SSL (HTTPS).
