Restoring Hadoop data

For restore only one backup host is used.

The following diagram provides an overview of the restore flow.

Figure: Restore flow

Restore flow

As illustrated in the diagram:

  1. The restore job is triggered from the master server.

  2. The backup host connects with the NameNode. Backup host is also the destination client.

  3. The actual data restore from the storage media starts.

  4. The data blocks are restored on the DataNodes.
