Restoring Hadoop data on the same Hadoop cluster

To restore Hadoop data on the same Hadoop cluster, consider following:

  • Use the Backup, Archive, and Restore console to initiate Hadoop data restore operations. This interface lets you select the NetBackup server from which the objects are restored and the client whose backup images you want to browse. Based upon these selections, you can browse the backup image history, select individual items and initiate a restore.

  • The restore browser is used to display Hadoop directory objects. A hierarchical display is provided where objects can be selected for restore. The objects (Hadoop directory or files) that make up a Hadoop cluster are displayed by expanding an individual directory.

  • An administrator can browse for and restore Hadoop directories and individual items. Objects that users can restore include Hadoop files and folders.
