Backing up a HBase cluster

You can schedule a backup job with a NetBackup policy. Or, you can run a backup job manually. See the NetBackup Administrator's Guide, Volume I for details on manual backups.

The backup process includes the following stages:

  1. Pre-processing: In the pre-processing stage, the first backup host that you have configured with the BigData policy, starts the discovery. At this stage, a snapshot of the complete backup selection is generated. The snapshot details are visible on the Region server web interface.

  2. Data transfer: During the data transfer process, one child job is created for each backup host.

  3. Post-processing: As part of the post-processing, NetBackup cleans up the snapshots on the Region server.

An overview of the backup process is available.

See Backing up HBase data.

Considerations

  • On the Hmaster, set the PasswordAuthentication field to Yes in the /etc/ssh/sshd_config file. After you update the file, restart sshd.

    Ensure that all the cluster servers support supports same hash key algorithm (RSA).

  • Snapshots are not cleaned up if you cancel a job manually. After you cancel the job you must manually delete the snapshots from the HBase shell.

  • If you take a backup of an empty table, you need to clean the snapshot manually from the HBase shell.
